“…Indeed, among the experimental studies, some focus on the influence of material properties on the evolution of the residual strength: fibre [8,11], resin [11][12][13], interface [14], stacking [15], transverse reinforcement like stitching [16,17] or Z-pinning [18], fabric instead of unidirectional tape [12,19], curing temperature [19]. There are also some experimental studies concerning the influence of test conditions such as: temperature during impact [20], hygrothermal conditions [12,[21][22][23], fatigue loading [24], or use of protective layer [25].…”

“…The decrease in mechanical properties after impact was identified years ago [1], and studies have tried to answer two main questions: how damage appears under impact conditions, and once damage has appeared, how it spreads when static or cyclic loading are acting on the structural component. The answers have led to a better understanding of the damage micromechanisms in impact loading conditions, related to the basic properties of resin, fibres, fibre matrix interfacing effects and the architecture of the laminate [2,3].…”

This work examines the response of carbon fibre reinforced epoxy matrix (CFRP) laminates at low impact velocity and in low temperature conditions. Square specimens of carbon fibre/epoxy laminates with different stacking sequences (unidirectional, cross ply, quasi isotropic and woven laminates) were tested using a Drop Weight Tower device. The test temperature ranged from 20 down to 150 8C. After the impact tests, the damage extension was measured by C Scan ultrasonic inspection and the damage mechanisms were studied by optical and scanning electron microscopy. Results showed the influence of temperature, of ply reinforcement architecture and of stacking sequence on the mechanical behaviour of the CFRP laminates subjected to low velocity impulsive loads.

“…Micro-cracking occurs at energies below ‫ܧ‬ ் and micro-cracking and delamination occur at energies above ‫ܧ‬ ் . Previous work in the area has shown that there is a local maximum in the load-time impact history that corresponds to the minimum applied load at which delamination occurs within the sample [3][4].…”

A study of impact damage morphology in unidirectional carbon/epoxy laminates was performed. A "load drop" method was investigated for prediction of the delamination threshold energy (E DT ) for impact. The impacted samples were subjected to uniaxial, in-plane compression to observe the growth of damage, failure modes, and residual strength. Samples were scanned before and after CAI using air-coupled throughtransmission ultrasound and amplitude C-scans were collected for visual inspection of damage. ABSTRACT.
