Strategies for energy-efficient frontal polymerisation processing and microstructural evaluation of fibre reinforced composites

Liquid composite moulding methods are widely applied for manufacturing of fibre reinforced polymer (FRP) composites and consist of two main stages: impregnation of fibrous reinforcements by a liquid monomer resin and curing of this resin. This thesis work ...

Process development of pre-impregnated hybrid thin-ply composites

Alexios Argyropoulos

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 ...

Novel 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 ...

Multiscale microshaping of functionally graded polymer-derived SiCN ceramics

Lorenz Hagelüken

Polymer-derived ceramics (PDCs) exhibit excellent properties and are compatible with many shaping techniques due to the liquid character of the preceramic polymers (PCPs). Furthermore, their properties are adjustable by modifying the precursor composition ...

Temperature effect on fatigue behavior of basalt fiber-reinforced polymer composites

Thomas Keller, Anastasios Vassilopoulos, Xing Zhao, Xin Wang

In this study, the temperature effect on the static and tension–tension fatigue behavior of basalt fiber‐reinforced epoxy polymer (BFRP) composites is investigated. The S–N curves, energy dissipation, stiffness degradation, and displacement increment with ...

Glass transition evaluation of commercially available epoxy adhesives for strengthening of steel structures with bonded CFRP plates

Ardalan Hosseini, Julien Michels

In the current study, the glass transition and tensile behavior of three different cold-curing two-component epoxies, commercially available as structural adhesives for carbon fiber reinforced polymer (CFRP) strengthening of concrete and steel structures, ...

Feasibility of accelerated curing for strengthening of steel members by prestressed bonded CFRP plates

Ardalan Hosseini, Elyas Ghafoori

Bond behavior and anchorage resistance of prestressed CFRP plates to steel substrate have been investigated in the current study. To do so, a set of single lap-shear and prestress release tests was performed on CFRP-to-steel bonded joints, and the feasibil ...

Prestressed FRP-strengthening and wireless monitoring of a metallic bridge in Australia

Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori

This paper presents the first application of pre-stressed carbon fibre-reinforced polymer (CFRP) material for strengthening of a metallic bridge in Australia. The study also describes the application of a wireless sensor network (WSN) system for long-term ...

Hardening acceleration/hardening retardation composition for building materials

Paul Bowen, Abhishek Kumar

Provided herein is a composition for use as a hardening regulator, e.g. hardening accelerator or hardening retarder, for building materials, as well as methods for producing thereof. The composition is characterized by a biphasic nature in which solid calc ...

Short-term bond behavior and debonding capacity of prestressed CFRP composites to steel substrate

Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori

In this study, the short-term bonding behaviors of prestressed CFRP plates to steel substrates and their debonding capacities have been investigated. For this purpose, single lap-shear and prestress release tests were performed on adhesively bonded CFRP-to ...
