Design and Formulate different HTRP materials reinforced CF

We develop and evaluate the mechanical properties of composites based on high temperature resistant polymers (HTRP) materials and carbon fibers (CF). The optimization of processing parameters and the 3D printability are studied. A. Diouf-Lewis

Design and 3D printing of bioinspired composite materials

Inspired by the toughness of the scales of the Polypterus Senegalus, we aim to produce multilayered multimaterial composites through 3D Printing. The aim is to design new inks for Direct Write with different mechanical properties. The superposition of inks with different properties allow for structure with superior resistance to concentrated loads. Y. Abderrafai

Fused deposition modelling of piezoelectric sensor with polyvinylidene fluoride(PVDF) and its nanocomposites

Piezoelectric sensors are widely used in many applications, but they are subject to the simple shape and complicated physical poling treatment.

Experimental characterisation and modelling of interfacial behaviour of additively manufactured composite structures

The non simultaneous solidification of the composite material filaments extruded during the Fused Deposition Modeling process introduces a local discontinuity where cracks can be initiated. Aim of this project is to empirically investigate the premature failure at the layers interface and to characterize and model the interfacial strength of the filaments. A. Lingua

This project aims at scaling the production of novel lightning strike protection systems for aircrafts. It will look for promising solutions currently being developed for lightning strike protection with an emphasis on the scalability of those methods. The target is to integrate a protective conductive layer or coating within the manufacturing process of the industrial partner and to scale the process to complete assemblies. D. Brassard


Additive manufacturing of green conductive thermoplastic polymer composites

Since the industry needs are aimed with more green technologies, the design of new functional materials should focus on eco-friendly components. Therefore, the goal of this project is to develop the electrically conductive polymer/carbon nanofiller systems for 3D printing using less hazardous, less toxic, renewable or biodegradable materials. P.

The project involves the additive manufacturing of metallic structures by binder jetting. This technique is using the very fast printing of a polymeric binder to hold small metallic powder together (from a flat powder bed) layer-by-layer.

Temperature effects during additive manufacturing of reinforced thermoplastic-based composites by Fused Deposition Modeling (FDM) and their mechanical properties.

FDM is one of the most popular AM techniques, but the restricted materials feedstock used and the process itself induce parts with limited mechanical properties. The first objective of this project is to study experimentally the effect of a heated environmental printing temperature on mechanical properties of samples made with an in-house composite filament, out of PA12 (and short carbon fibers). The second objective is to print and determine mechanical properties of samples made with High Performance Polymers (HPP) feedstock like PC, PPSU, PEI and PEEK. C.Hérard
