“…This was attributed to the occurrence of multiple small delaminations in the well dispersed hybrids compared to extensive fibre breaks or delaminations on the compression side in the less dispersed hybrids. The same authors confirmed these results on aramid/basalt fibre hybrids [110].…”

Fibre-reinforced composites are rapidly gaining market share in structural applications, but further growth is limited by their lack of toughness. Fibre hybridisation is a promising strategy to toughen composite materials. By combining two or more fibre types, these hybrid composites offer a better balance in mechanical properties than non-hybrid composites. Predicting their mechanical properties is challenging due to the synergistic effects between both fibres. This review aims to explain basic mechanisms of these hybrid effects and describes the state-of-the-art models to predict them. An overview of the tensile, flexural, impact and fatigue properties of hybrid composites is presented to aid in optimal design of hybrid composites. Finally, some current trends in fibre hybridisation, such as pseudoductility, are described.

“…Among the limited publications in this field of study [14][15][16], Pegoretti et al [14] have studied the low-velocity impact behavior of E-glass/PVA hybrid laminated woven composites in two structures. However, very little work has been done to evaluate the effect of hybridization on the impact behavior of polymer-matrix composites, especially for woven fabric composites.…”

In this study, the impact and flexural properties of woven basalt fiber/phenolic (BFP), woven carbon fiber/ phenolic (CFP) and woven basalt/woven carbon hybrid phenolic (BCFP) composites are investigated. The hybridization effect of woven basalt and woven carbon fibers on the impact energy absorption and flexural properties is investigated for various weight ratios of basalt/ carbon hybrid fibers such as 1:0, 0.83:0.17, 0.68:0.32, 0.61:0.39, 0.34:0.66 and 0:1. It is found that the impact properties of the composites are strongly improved when the basalt fiber increased. Impact energy absorption of CFP composite showed a regular trend of increase with increasing weight ratio of basalt fiber in hybrid fiber composite. The lowest impact energy absorption values are found for the composites with weight ratio 0:1 (CFP), with average of 70 kJ/m 2 . Corresponding values for energy absorptions are obtained for 0.83:0.17, 0.68:0.32, 0.61:0.39, 0.34:0.66 basalt/carbon weight ratio in hybrid composites. The impact energy absorption of hybrid composites (BCFP) shows the highest value with an average of 219 kJ/m 2 , when the weight ratio of 0.83:0.17 is used. Finally, the impact energy absorption of BFP composites with the weight ratio of 1:0 shows the highest value of 268 kJ/m 2 . The experimental evidence shows that the hybrid composites based on combinations of stiff carbon fibers and tough basalt fibers have good flexural properties and therefore, they can be used as promising materials in a number of engineering sectors such as the protective structures.

“…Although the behaviour of fabric-reinforced composites subjected to low-velocity impact is widely studied, e.g. in [6][7][8][9][10], among others, the loading is mostly of the drop-weight type. The large-deflection dynamic bending behaviour of sports products can be accurately assessed with impact tests on un-notched samples using pendulum-type hammers, which is rarely investigated.…”

Citation: ULLAH, H., HARLAND, A.R. and SILBERSCHMIDT, V.V., 2015.Dynamic bending behaviour of woven composites for sports products: experiments and damage analysis. Materials and Design, 88, Additional Information:• This paper was accepted for publication in the journal Materi- CFRP laminates of various orientations were tested at loads increasing up to failure to determine their energyabsorbing capability. On-axis laminates demonstrated better strength and stiffness whereas off-axis laminates exhibited good energy-absorbing capability. However, for applications demanding strength, stiffness and energy absorption as in sports products, a combination of both types of plies, as in a quasi-isotropic layup, is an optimum choice. Micro-computed tomography (micro-CT) analysis of the tested specimens showed that matrix cracking, delamination and tow debonding were the dominant damage modes at the specimen's impact location, whereas fabric fracture occurred at the bending location. Further, a catastrophic brittle fracture was observed in the on-axis laminates whereas the off-axis laminates exhibited pseudo-ductile behaviour thanks to matrix cracking and fibre trellising before their failure at higher energies.
