A three-dimensional multi-scale computational homogenisation framework is developed for the prediction of nonlinear micro/meso-mechanical response of the fibre-reinforced polymer (FRP) composites. Two dominant damage mechanisms, i.e. matrix elasto-plastic response and fibre-matrix decohesion are considered and modelled using a non-associative pressure dependent paraboloidal yield criterion and ...

Over the last years, the demand for high strength and low weight materials, such as fabric-reinforced plastics, has grown in the aeronautical industry. By decreasing the production cost with short production cycle times and increasing reproducibility by automation, fabric-reinforced plastics are becoming increasingly better economical competitors to other construction materials such as for exam...

Continuous fibre reinforced composites are now firmly established engineering materials for the manufacture of components in the automotive and aerospace industries. In this respect, composite fabrics provide flexibility in the design manufacture. The ability to define the ply shapes and material orientation has allowed engineers to optimize the composite properties of the parts. The formulatio...

In brittle materials such as concrete and ceramics, fibre reinforcement has been widely accepted as an effective way of improving their strength and toughness. In addition, a notable pseudo strain-hardening phenomenon can contribute to a significantly enhanced ductility of the composite when an adequately designed fibre system is used. This condition was first proposed by Aveston et al. [1], an...

Chirped fibre Bragg grating (CFBG) sensors have been embedded within the adhesive bondline of single-lap bonded composite joints, fabricated using a transparent glass fibre reinforced plastic (GFRP) adherend bonded to a carbon fibre reinforced plastic (CFRP) adherend. During fatigue cycling, disbonds initiated adjacent to the cut ends of one, or both, of the adherends and the disbonds propagate...

In the present study, core-reinforced braided composite rods (BCRs) were developed and characterized for strain sensing capability. A mixture of carbon and glass fibre was used in the core, which was surrounded by a braided cover of polyester fibres. Three compositions of core with different carbon fibre/glass fibre weight ratios (23/77, 47/53, and 100/0) were studied to find out the optimum co...

The effect of Kevlar fibre surface modification and hybridization on metal laminates (FMLs) was investigated in this paper. Fibre are interlaced layers thin metals fibre-reinforced plastics that constitute a hybrid composite material. flexural strength composites from the three-point bending test at various ratios sequence FML composites. Glass fibre, aluminum were taken for laminating reinforc...

Short randomly oriented banana and sisal hybrid fibre reinforced polyester composites, banana/polyester composites and sisal/polyester composites were fabricated at different fibre loading say, 0.20 to 0.50 Vf. Composites were prepared by varying the relative volume fraction of the two fibres at each fibre loading. When the fibre loading was increased; tensile, flexural and impact properties in...

Holmes and Shuler [1] recently found that significant internal heating occurs during the cyclic loading of fibre-reinforced ceramics. In their investigation, conducted with cross-ply carbon fibre/SiC matrix composites (hereafter referred to as Cf/SiC), it was observed that the extent of internal heating was strongly influenced by the peak fatigue stress and loading frequency. For example, durin...

OBJECTIVE The aim of this study was to determine bonding properties of two types of fibre-reinforced composite (FRC) posts cemented into root canals of molars. Serrated titanium posts served as reference. METHODS Prefabricated carbon/graphite FRC posts with cross-linked polymer matrix and individually formed glass FRC posts with interpenetrating polymer network (IPN) polymer matrix were compa...
