Numerical investigation of two-dimensional Mode-II delamination in composite laminates
Thomas Keller, Anastasios Vassilopoulos, Congzhe Wang
Existing standards for delamination tests on composite materials typically employ one-dimensional (1D) beam specimens. However, such specimens may not represent real delamination scenarios in composite structures, where cracks tend to propagate in two dime ...
London2024Contributions to rebar-to-concrete interaction and its structural implications for design and monitoring applications
Bond between reinforcing bars and concrete has been the focus of extensive research over the last century. This is well-justified as the functioning of reinforced concrete intimately depends on the interaction between rebar and concrete, as for example cra ...
EPFL2024Frequency response of fiber reinforced DEAs
Yves Perriard, Yoan René Cyrille Civet, Thomas Guillaume Martinez, Stefania Maria Aliki Konstantinidi, Markus Koenigsdorff
Dielectric Elastomer Actuators (DEAs) have emerged as versatile and promising devices for a multitude of applications, including soft robotics, haptic interfaces, and artificial muscles. DEAs are an interesting soft actuator technology due to their high en ...
Society of Photo-Optical Instrumentation Engineers (SPIE)2024Mode I and Mode II fracture behavior in pultruded glass fiber-polymer - Experimental and numerical investigation
Many recent works have shown that the capacity of pultruded glass fiber-polymer structural members is governed by interlaminar failure. However, there is still a lack of information regarding the fracture properties associated and the best techniques to be ...
London2023Effect of wettability and textile architecture on fluid displacement and pore formation during infiltration of carbon fibrous preforms
Véronique Michaud, Baris Çaglar, Helena Luisa Teixido Pedarros
We seek to address how air entrapment mechanisms during infiltration are influenced by the wetting characteristics of the fluid and the pore network formed by the reinforcement. To this end, we evaluated the behavior of two model fluids with different surf ...
London2023Thermophysical and thermomechanical properties of basalt-phenolic FRP rebars under high temperature
Thomas Keller, Hongwei Zhu, Ting Li, Jiahui Shen
An experimental investigation was conducted on the thermophysical and thermomechanical properties of phenolic-basalt fiber-reinforced polymer (P-BFRP) rebars subjected to high temperature. As a comparison, vinylBFRP (V-BFRP) and epoxy-BFRP (E-BFRP) rebars ...
ELSEVIER SCI LTD2022Multi-recycling of polypropylene fibre reinforced concrete: Influence of recycled aggregate properties on new concrete
Herein, an investigation of multi-generational recyclability of polypropylene fibre reinforced concrete (PPFRC) was performed. The parent concretes were produced with 0 and 6 kg/m(3) of polypropylene fibres. After recycling, the obtained coarse recycled co ...
ELSEVIER SCI LTD2022Novel tooling for direct melt impregnation of textile with variotherm injection moulding: Methodology and proof of concept
Véronique Michaud, Vincent Werlen, Christian Rytka
Thermoplastic compression resin transfer moulding coupled with injection moulding is an appealing process for the production of thermoplastic composites. However, its implementation at an industrial scale remains challenging as variotherm injection mouldin ...
SAGE PUBLICATIONS LTD2022Kinematic and mechanical response of dry woven fabrics in through-thickness compression: Virtual fiber modeling with mesh overlay technique and experimental validation
Véronique Michaud, Baris Çaglar, Lode Geeraard Daelemans
The through-thickness compressive behavior of fabric reinforcements is crucial in liquid composite molding manufacturing processes. Predictive simulations of the compressive response are thus necessary to enable a virtual processing workflow. These are com ...
2021Monitoring of Torque Induced Strain in Composite Shafts with Embedded and Surface-Mounted Optical Fiber Bragg Gratings
John Botsis, Georgios Violakis, Georgios Pappas
In this study, silica glass, optical fiber Bragg gratings (FBGs) are used for torque-induced strain monitoring in carbon fiber reinforced polymer (CFRP) hollow shafts toward the development of a methodology for structural load monitoring. Optical fibers w ...
