FOUNDING SOURCE: Experimental Demonstrative Projects - PN-III-CERC-CO-PED-2-2019
PROJECT CODE: PN-III-P2-2.1-PED-2019-4138
CONTRACT NUMBER: 321PED
PROJECT DURATION: August 2020 – July 2022
PROJECT BUDGET: RON 600,000 +20,000 Co-financing R&D Consultanta si Servicii, Bucuresti
PROJECT CONSORTIUM:
CO - National Institute of Research and Development for Technical Physics, NIRDTP Iasi
P1 –„ Gheorghe Asachi” Technical University of Iasi – TUIASI
P2 – „Petru Poni" Institute of Macromolecular Chemistry (PPIMC), Iasi
P3 - R & D Consultanta si Servicii, Bucuresti
SUMMARY
The project aims to develop a novel smart composite system, constituted of shape memory alloy (SMA)/ amorphous magnetic materials embedded into elastomeric matrices (SMA-AM/ E) with self-controlled configuration and extended functionality, dedicated to the operation, detection and monitoring of fluid volume, temperature and transition parameters, such as recipients with controlled volume, hydraulic pumps, multifunctional pipes for complex fluid transportation or even stents. Thermoelastic SMAs, such as Ni-Ti-Cu(Nb, Ta) that are nonmagnetic and martensitic at room temperature (RT), will be designed and produced by the Company „R & D Consultanță și Servicii” (P3), under the form of cylindrical ingots. The “ Gheorghe Asachi” Technical University of Iasi (P1) will homogenize the ingots that will be cut, hot rolled, heat treated and thermomechanically trained into active elements, which will be attached firstly into 2D flexible modules comprising 3 to 6 elements and finally into 3D systems. The National Institute of Research and Development for Technical Physics Iasi (CO) will produce, process and characterize the amorphous magnetic microwires, melt spun from Co-based ultra-soft magnetic alloys. CO will study the integration of amorphous microwires into the host composite consisting of a SMA skeleton incorporated into flexible elastomers. “Petru Poni” Institute of Macromolecular Chemistry (P2) will synthesize and characterize the elastomeric matrix based on polysiloxanes, which needs to be flexible and temperature-resistant. CO, assisted by P1 and P2 will test the functionality of several variants of experimental smart systems with different number of 2D modules and different initial configurations of the modules comprising 3-6 active elements
OBJECTIVES
The main objective of the project is to develop a laboratory model of a complex system built up from smart composite materials, with extended functionality dedicated to the operation, detection and monitoring of fluid volume, temperature and transition parameters, such as recipients with controlled volume, hydraulic pumps, multifunctional pipes for complex fluid transportation or even stents. Reaching this objective shall be possible by capitalizing the knowledge and results obtained so far by the partners involved in project’s implementation, individually and in collaboration.
EXPECTED RESULTS
Smart composite system with self-controlled 3D configuration, flexible structure, and feed-back monitoring functions, developed from shape memory alloys as active elements / magnetic sensors based on amorphous magnetic materials as sensing elements, embedded in elastomeric matrices.
