A process has been developed where multiple yarns of commingled glass and polypropylene are heated and placed to a desired geometry. The placed unidirectional (UD) tow is then encapsulated by over-moulding with glass mat thermoplastics (GMTs). The effects ...
The mode I inter-laminar fracture toughness of advanced knitted textile composites was investigated. Two complex weft-knitted glass fabrics were selected for the study: a triple rib knit and a Milano knit were impregnated with a tough epoxy resin and teste ...
PROBLEM TO BE SOLVED: To provide a resin microchip having a microchannel having a transparent flow passage of low absorption in an ultraviolet area sealed with a fine upper substrate of excellent surface smoothness and high dimensional precision. ;SOLUTION ...
Pre-stress bonded composite patch is a promising technique to reinforce steel member damaged by fatigue. ifhe effectiveness of this technique was verified by fatigue tests on notched steel plates. Results showed that the application of carbon fibre reinfor ...
PROBLEM TO BE SOLVED: To provide a microchip made of a resin with a microchannel with a channel sealed by an upper substrate which is transparent and absorbs little in ultraviolet region, is minute and has satisfactory surface smoothness, and is high in di ...
The development of a reactive pultrusion process is presented by considering the advantages of an in situ polymerisation of thermoplastic lauryllactam monomers. The specifics of the reaction injection unit, of the fibre-drying oven and of different pultrus ...
The development of internal stress during cure of epoxy and hyperbranched polymer- modified epoxy resins was characterized, taking into account the evolving viscoelastic properties, the volumetric shrinkage due to the chemical reaction, and the thermal exp ...
A method is presented for studying fibre damage in continuous fibre reinforced composites. It is based on contrasting the transmission of light through intact translucent fibres with the light through fractured or dead-ended fibres. The method is applied i ...
The stress transfer from broken to unbroken fibers in fiber-reinforced polymer-matrix (PMC) and aluminum-matrix (AMC) composites is studied using a detailed 3D finite element model (FEM) and using the standard shear-lag model (SLM). The stress transfer pre ...
The present work focuses on the interfacial mechanical behaviour of a model composite consisting of a solid droplet on a fibre, generally referred to as the microbond test. The interfacial adhesion is derived from the modelling of stress transfer in the mi ...
