Multi-scale characterization and modeling of notched strength and translaminar fracture in hybrid thin-ply composites based on different carbon fiber grades
Owing to their high specific stiffness and strength, Carbon Fiber Reinforced Composites (CFRP) are ideal candidates for the development of lightweight high-performance structures. Within this family, thin-ply composites allow for wider design freedom and p ...
EPFL2023A life cycle analysis of novel lightweight composite processes: Reducing the environmental footprint of automotive structures
Véronique Michaud, Baris Çaglar, Vincent Werlen, Christian Rytka, Colin Gomez
In this study, three novel thermoplastic impregnation processes were analyzed towards automotive applications. The first process is thermoplastic compression resin transfer molding in which a glass fiber mat is impregnated in through thickness by a thermop ...
ELSEVIER SCI LTD2022Recycled Glass Fiber Composites from Wind Turbine Waste for 3D Printing Feedstock: Effects of Fiber Content and Interface on Mechanical Performance
Rodolphe Henri, Kazem Fayazbakhsh
This research validates the viability of a recycling and reusing process for end-of-life glass fiber reinforced wind turbine blades. Short glass fibers from scrap turbine blades are reclaimed and mixed with polylactic acid (PLA) through a double extrusion ...
2019Assessment of capillary phenomena in liquid composite molding
Véronique Michaud, Baris Çaglar, Feyza Karasu Kiliç, Cem Tekin
The interplay between capillary and viscous forces plays a significant role for optimal part quality in fiber-reinforced composites manufactured by Liquid Composite Molding (LCM); these are however difficult to analyze during flow. Two approaches are propo ...
2019Strategies for faster impregnation in melt thermoplastic resin transfer molding process
Continuous fiber thermoplastic composites are potential substitutes of steel in structural automotive components, since they combine fiber strength and rigidity with ductility, potential recyclability and low density of the thermoplastic (TP) matrix. Resin ...
EPFL2018Hybrid Processing of Thermoplastic Based Multimaterials
There is a growing interest in exploring novel material combinations and processing technology to manufacture complex 3D shaped polymer and composite structures. In the field of prosthetics and orthotics, this need is significant with additional challenges ...
EPFL2017Screening method for the onset of bonding of molten polyamide resin layers to continuous fiber reinforced laminate sheets
Thermoplastic polymer composites (TPC) with multiple fabric layers of continuous fiber reinforcement are laminate sheets designed to be thermally stamped and overmolded leading to low cycle times and thus high volume composite parts. Injection over-molding ...
2016Post-wrinkling behavior of webs in GFRP cell-core sandwich structures
Thomas Keller, Anastasios Vassilopoulos, Behzad Dehghan Manshadi
Similarly to the post-buckling behavior of steel girder webs, the post-wrinkling behavior of glass fiber reinforced polymer (GFRP) cell-core sandwich webs can increase their ultimate shear strength. Post wrinkling is, however, different from post-buckling ...
Elsevier2016Mean-Field Description of Plastic Flow in Amorphous Solids
Failure and flow of amorphous materials are central to various phenomena including earthquakes and landslides. There is accumulating evidence that the yielding transition between a flowing and an arrested phase is a critical phenomenon, but the associated ...
