“…8. This finding agrees with impact testing results from a previous VPPMC study [21] and also compares well with studies on glass fibre-epoxy plates, carbon fibre reinforced laminates and graphite fibre reinforced epoxy [43][44][45]. It is also interesting to note the positive y-axis intercept; this implies that even without a larger debonded area (i.e.…”

Viscoelastically prestressed polymeric matrix composites (VPPMCs) are produced by subjecting fibres to creep, then releasing the creep load before moulding. Previous work has demonstrated mechanical property improvements up to ~50% from nylon 6,6 fibre-polyester resin VPPMCs, compared with control (unstressed) counterparts. Since fibre stretching and moulding processes are decoupled, the time interval between releasing the fibre stretching load and moulding (delayed moulding) offers considerable production flexibility. This paper investigates delayed moulding over 0-1272 h, using fibres stored at 20 °C and -25.4 °C. Charpy impact tests demonstrated increased energy absorption from all VPPMC samples compared with control counterparts, this increase reducing with delayed moulding time. A 1272 h delay gave an increase of ~23% for fibre storage at 20 °C, and ~40% at -25.4 °C, the latter demonstrating "decelerated" ageing. For all samples, the magnitude of fibre-matrix debonding (the principal energy absorption mechanism) increased linearly with impact energy data.

“…While advanced finite element models for impact on composites have been developed [14][15][16][17][18][19], they have rarely been applied to fibre-hybrid composites [20,21]. As a consequence, the current state-of-the-art in impact on fibre-hybrid composites is mainly limited to visual observations rather than being governed by a general framework for understanding their behaviour.…”

The impact resistance of fibre-reinforced composites is vital in many applications, and can be improved by exploiting synergies in fibre-hybridisation. These effects are however not sufficiently well understood in the literature. Penetration impact tests were hence performed on carbon/glass hybrids, and the results were linked to the flexural behaviour and translaminar fracture toughness. The results revealed large synergetic effects of up to 40% compared to the linear rule-of-mixtures. The results are also the first to reveal that creating a translaminar fracture surface can strongly contribute to the energy absorbed during penetration impact: 56% for an all-carbon fibre composite and 13% for an all-glass fibre composite. These results prove that strategies for maximising the translaminar fracture toughness can also be exploited to maximise the penetration impact resistance of fibre-hybrids. In carbon fibre composites in particular, ply blocking, using larger yarns and introducing micro-cuts should therefore increase the penetration impact resistance

“…Most of these researchers focus on laminated composites that are unloaded before low velocity impact [1][2][3][4][5]. But with regard to applications industry, it is rather unlikely that the impacted structures are unloaded.…”
