Abstract:
Sealing solutions play a crucial role in any space application. O-rings are rubber seals used as "sealing solution" to prevent unwanted loss of gas or liquid. For our purposes, the materials used for O-rings, must be tested in different specific operating conditions of the outer space. Due to the insufficient low-temperature testing of the materials used for O-rings, January 28, 1986, one tragic O-ring failure happened in the framework of NASA’s space shuttle program. Seven astronauts were killed when the Challenger exploded at just over a minute after the launch. After this catastrophe the research, development and innovation activities were intensified, in order to obtain new and advanced elastomeric materials to manufacture O-rings used in the manned space programs, for the achievement of good seals, to provide high stability at low / high temperatures in different environments, ozone, radiation, amongst others. This project proposal is included in the same direction of research.
The main objective of the proposal is to improve seal characteristics of the material in order to apply it in aerospace and space field, through a new concept of technology and chemical composition. To achieve this objective, we will pursue the development of some advanced materials based on ethylene-propylene -diene terpolymers (EPDM), butyl rubber (IIR) and nano-fillers (silicon carbide - SiC, organically modified montmorillonite - OMMT) with enhanced properties (high stability to radiation, ageing and temperature, low temperature flexibility, long-term compression properties, very good physical, mechanical and chemical properties etc.), designed to obtain O-rings with potential use in space, aeronautics, security and related areas.

Abstract:
The overall objective of the project is to increase the competitiveness of SC Protect Styl Industry SRL by experimenting and developing a fireproof material based on styrene-butadiene-styrene rubber (SBS) reinforced with nano (micro) particles of CaCO3/MgCO3 and halloysite (a thermally stable alumino-silicate) functionalized with organo-inorganic groups, intended for making protective shoe soles for firefighter's footwear, which comply with product and environmental standards (EN 15090 CE and EN ISO 20345 CE) in force. Due to the extremely high flammability of SBS, without the addition of specific fire retardants, this type of rubber cannot be used in applications requiring high temperatures. In the case of fire-resistant footwear, the sole must withstand up to 300°C for at least 60 seconds. Currently, the most efficient and inexpensive additives for fireproofing various types of elastomers are generally chlorinated and brominated compounds in combination with Sb2O3. Given that antimony trioxide is classified as potentially carcinogenic, and chlorinated and brominated compounds are considered toxic, persistent in the environment and bioaccumulative in the body, it is necessary to replace these additives with healthier ones. However, attempts to replace them with intumescent agents, such as hydroxides, mica, etc., fail to deliver flame retardancy/optimal mechanical properties. For these reasons, the project will use CaCO3/MgCO3 additives as fire retardants, which at temperatures of 400°C decompose with the formation of CO2. Furthermore, functionalizing the surface of flame retardants and halloysite with titanium isopropoxide/polydimethylsiloxan e will improve the dispersibility, thermal, mechanical, chemical and UV stability of SBS. From this composite, INCDTP-ICPI will make shoe soles by injection and the beneficiary will make and promote the firefighter boots.

Abstract:
The project aims to exploit the expertise and technical-scientific competences of the provider, in order to elaborate and implement new products and “low cost” continuous flow manufacturing processes, environmental and quick, adapted to existing equipment and installations for the beneficiary. The aim is to create new types of advanced eco-nano-materials based on ethylene-propylene-terpolymer (EPDM), polyethylene (PE), plasticized starch and organically modified montmorillonite (OMMT), without toxic ingredients or with minimal amounts of such ingredients. These may be processed by injection method using the existing equipment available to the beneficiary, thus eliminating the curing operation in which toxic gases are released and which is a high electricity consuming operation. The new materials will fulfil required criteria for manufacturing injected protective soles resistant to aggressive chemicals both due to the composition (EPDM and PE are highly water, acid and concentrated alkali resistant, etc.), and to obtaining technologies (melt compounding, dynamic curing, melt intercalation in order to obtain nanocomposites, suitable compatibilisation methods) leading to materials with advanced properties. There will be a great market demand for the new range of soles for protective footwear because: (1) they can successfully stand out on an organized market, in bids, compared to other similar products, many of which are low quality or counterfeit, because they meet conditions set by standards in the field and EU requirements, (2) “eco” products are favoured on the market because they lead to the development of sustainable economy and ensures environmental protection. The provider's implementation team is made up of: 2 I degree scientific researchers, 1 III degree scientific researcher, 2 technicians and 1 plastics processing technician, with relevant experience and expertise in the area of the project topic.

Abstract:
The project aims to scientifically design and develop footwear for older people in Romania, based on specific pathologies of this age group, affecting the size and shape of feet using innovative manufacturing technologies. The special purpose of this type of footwear aims at preventing foot deformation and compensating dysfunctions/disabilities caused by aging processes, with the purpose of facilitating gait. This type of footwear must fulfill the role for which it was designed and built, which is to protect the foot from disruptive external factors, through the optimal correlation between foot sizes and shoe, by increasing foot support both in orthostatic position and during gait to ensure the biped position of the body, to diminish the effort of osteoarticular and musculo-ligamentous system while exercising their functions and, last but not least, design factors considering anatomical elements, the materials used, the upper and lower assembly design, as well as adopted technologies and the compatibility between these elements.
The project is divided into three main stages: research, analyzing the current situation of pathologies (morpho-functional changes) characteristic for feet of elderly population and the situation of the footwear market regarding the requirements of the elderly; the development phase, analyzing anthropometric and biomechanical parameters of feet of elderly population, types of deformities and diseases, their frequency, severity and consequences. Based on these data, prototypes will be made combining 3D last modeling techniques with 3D foot scanning and shoe design in CAD/CAM system to ensure the proper shape and size inside the footwear. In the third phase dimensional and functional comfort will be tested by wearing sample footwear and making the necessary corrections as a result of the observations made, and then footwear for the elderly will be developed by the SME.
The results of this research will lead to the development of functional and comfortable footwear products, properly adapted to the particularities and frequent variations of the foot, so as to restore normal functioning of feet for the elderly, and relieve problems caused by age-specific pathologies. Designing footwear for the elderly involves establishing the foot anthropometric parameters and decision making in the context of understanding normal and pathological gait biomechanics using a variety of tools and techniques such as measuring pressures in barefoot walking, postural analysis, measuring the ground reaction force using the force plate. The role of footwear for the elderly is to respect the morphology of the foot and modify the reaction vector of the supporting surface, so as to ensure an efficient gait in daily activities, maintaining mobility, autonomy, participation in social life, resulting in increased quality of life.
The consortium of this project consists of national research and development institute, three universities and a SME. The experience gained by research teams in the area of footwear development, anthropometry studies, biomechanics studies, medical studies and market studies, and understanding the need to develop advanced technologies for footwear manufacturing, justify the collaboration of these teams.
Supporting the SME in the consortium by introducing this technology is a strategic direction for development with significant potential in ensuring health and increasing quality of life for the population, as well as in developing this sector.

Abstract:
Domeniul alimentar este de interes pentru economie si reprezinta o problema de stat in procesarea alimentelor in mediu de igiena si securitate. Reperele elastomerice pentru industria alimentara sunt o parte importanta a echipamentelor de procesare a alimentelor, in special a carnii. Echipamentele de procesare sunt numeroase si cu elemente constructive variate (carucioare, celula de afumare, carlige, navete si tavi, cuier organe si preparate, dispozitiv de spalat si intors, dispozitiv de taiat, cimbare, malaxor, masa curatat, jgheab, presa sunca si preparate etc.). Aceste echipamente sunt utilizate in medii de lucru cu temperaturi ridicate (150–2000C), specific sterilizarii si procesarii si sunt dotate cu repere elastomerice, care datorita mediului se deterioreaza, se cumpara din strainatate si sunt realizate din materiale costisitoare. Reperele elastomerice utilizate in domeniul alimentar este foarte divers, precum: garnituri de etansare, chedere, furtunuri, dopuri, roti etc.
Necesitatea temei a aparut datorita cererii de piata a reperelor utilizate la echipamentele de procesare de catre firmele nationale ce utilizeaza repere exportate din alte tari, greu accesibile ca timp si pret. In Romania nu sunt firme care sa realizeze aceste produse.
Obiectivul proiectului este de a realiza o arhitectura polimerica pe baza de polipropilena, poliamida, compatibilizator de tip polipropilena maleinizata si aditivi. Utilizarea compozitului realizat va realiza un produs rezistent la temperature ridicate, stabil si usor de procesat in produse finite prin tehnologia de injectie in matrita. La procesare nu se obtin deseuri pentru ca materialul poate fi reutilizat fara sa isi piarda proprietatile initiale. Prin realizarea experimentarilor propuse se urmareste elaborarea recepturilor pentru arhitectura polimerica si procesarea acesteia in produse finite utilizate la echipamentele de procesare a carnii care sa respecte normele calitative si de toxicologie impuse de directive UE.

Abstract:
Protectia muncii este o problema de stat si cuprinde ansamblul normelor si regulilor de tehnica a securitatii si igiena a muncii, care au ca scop asigurarea celor mai bune conditii de munca, prevenirea accidentelor si îmbolnavirilor profesionale pentru persoanele care muncesc în conditii deosebite. In acest context s-a dezvoltat subiectul acestui proiect de realizare a unui material pentru talpi de incaltaminte de securitate si protectie pentru medii de lucru cu risc termic, precum locurile de munca cu podele calde, cu posibile contacte cu materiale calde sau cu materiale in stare de incandescenta la temperatura mediului de frecventa mare in sectoarele metalurgice, constructii de masini, petrolier, pompieri etc.
Necesitatea abordarii temei a aparut datorita cererii de piata a incaltamintei de protectie rezistenta la risc termic comoda si rezistenta minim 12 luni. Incaltamintea existenta pe piata, cel putin cea din Romania este incomoda si deficitara, cu durata de folosire mult sub cea prevazuta in normativul de distribuire a echipamentului de protectie, respectiv 5-6 luni fata de 12 luni. Este evidenta necesitatea realizarii unor talpi pentru bocanci cu expunere de durata la temperaturi excesive care sa aiba o durata de utilizare de peste 10 luni, pastrand in aceasta perioada un confort acceptabil si proprietatile initiale. In prezent, se utilizeaza incaltaminte cu talpa de lemn, piele sau cauciuc natural prelucrat si vulcanizat in presa.
Astfel, obiectivul proiectului este de a realiza un material pentru talpa vulcanizata care sa corespunda conditiilor de lucru in medii cu risc termic.
Prin realizarea experimentarilor propuse in proiect se urmareste elaborarea si experimentarea recepturilor pentru talpi, respectiv talpa vulcanizata in matrita, materiale pentru talpa intermediara, si realizarea de catre beneficiar a unui model de incaltaminte care sa respecte conditiile de purtare in medii de lucru cu risc termic.
