Impact resistance and energy absorption mechanisms in hybrid composites

Fibre hybridisation in polymer composites: A review

“…Since the impact face is loaded in compression and the other face is loaded in tension, the damage mechanisms can be different. Surprisingly, the conclusions of Jang et al [100] seem to contradict with the conclusions of Sayer et al [98] and Park and Jang [99]. This is most likely caused by differences in the damage mechanisms, which are triggered by differences in the materials and their interfaces.…”

“…Jang et al [100] investigated asymmetric aramid/carbon fibre hybrids with only two layers and did not find a significant improvement depending on which layer was on the impacted side. This was attributed to the similar impact behaviour of both reference composites, which seems surprising for such dissimilar fibre types.…”

The effect of hybridization on the GFRP behavior under high velocity impact

“…The same authors concluded that the work of fracture by impact and the flexural elastic modulus of mixed GFRP/CFRP composites are both simple functions of composition corresponding to a matrix rule based on the properties of plain GFRP and CFRP [8]. Jang et al [9] showed that hybridizing graphite composites with additional tough high strain-to-failure fibers give better damage resistance of composite structures under impact loading. The obtained results also implies that the stacking sequence is a major factor governing the overall energy absorbing capability of the hybrid structure, and the penetration resistance of hybrid composites appeared to be dictated by the toughness (strength plus ductility) of their constituent fibers.…”

Rational design of fiber-reinforced hybrid composites: A global load sharing analysis

“…Hybrid composites, primarily with polymer matrices, have been studied extensively. Several properties have been investigated, including the composite modulus [4], tensile strain to failure [3e8], tensile/flexural strength [4,6,8e10], impact/fracture resistance [6,7,11,12], and fatigue life [13]. A recent and comprehensive review of these studies can be found in Ref.…”
