Investigation of mycelium film as the adhesive for poplar veneer bonding: insight into interfacial bonding mechanisms
The emergence of mycelium-bonded biocomposites has been stimulated in the quest for sustainable development. These biocomposites exhibit enhanced mechanical properties through hot pressing, with mycelium playing a crucial role as both the adhesive and rein ...
Abingdon2024Process development of pre-impregnated hybrid thin-ply composites
Thin-ply composites, obtained with recently developed fiber spreading techniques, rapidly gained industrial interest because they offer a large composite design freedom, and lead to a composite tensile strength that is close to that of the individual fiber ...
EPFL2023Multi-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 ...
EPFL2023Energy dissipation in fiber-polymer composites adhesive joints under cyclic loading
Sustainable development has emerged as a paramount consideration in various fields of industry, including construction, to preserve the environment and its finite resources. Lightweight structures, such as fiber-polymer composite structures, address both s ...
EPFL2023Incorporation of Lignin in Bio-Based Resins for Potential Application in Fiber-Polymer Composites
Mário Alexandre De Jesus Garrido, Mateus De Assunção Hofmann
Bio-based resins, obtained from renewable raw materials, are a more sustainable alternative to oil-based resins for fiber-reinforced polymer (FRP) composites. The incorporation of lignin in those resins has the potential to enhance their performance. This ...
MDPI2023The Development of Aptamer-Coupled Microelectrode Fiber Sensors (apta-?FS) for Highly Selective Neurochemical Sensing
The selective and sensitive sensing of neurochemicals is essential to decipher in-brain chemistry underlying brain pathophysiology. The recent development of flexible and multifunctional polymer-based fibers has been shown useful in recording and modulatin ...
AMER CHEMICAL SOC2023Novel multi-crack damage approach for pultruded fiber-polymer web-flange junctions
This paper aims to propose a novel approach to assess the multi-crack behavior of layered fiber-polymer composites. The Compliance and R-curves generated from this novel approach were useful to understand the multiple delamination process, enabling to eval ...
London2023Influence of Fiber Orientation on the Elastic Limit Tensile Stress of UHPFRC
Eugen Brühwiler, Emmanuel Denarié, Jian Zhan
The elastic limit tensile stress of UHPFRC is governed by contributions of the cementitious matrix and the fibrous skeleton. This paper finds that fiber orientation has significant influence on the matrix tensile strength of UHPFRC, while this is not consi ...
2023Supramolecular Modifications of Semicrystalline Polymers
Supramolecular interactions play an important role in defining the structure and the resulting mechanical properties of materials. For instance, interchain hydrogen-bonding in PAs gives them superior strength and stiffness in engineering materials, while t ...
EPFL2023CRACK SHIELDING MECHANISMS OF INTERLAYERED EPOXY MATERIALS UNDER QUASI-STATIC AND FATIGUE LOADING
Anastasios Vassilopoulos, Dharun Vadugappatty Srinivasan
This research explores the capability of PEI and PVDF thermoplastic interlayers to arrest cracks in epoxy materials modified with short-glass fibers and core-shell rubber particles. It also investigates the effect of interlayer position, the number of inte ...
