“…Carbon and glass fibre composites have been the most studied under impact loading. [1][2][3][4][5][6][7][8][9] Of these, Naik et al 3,4 investigated the impact behaviour of E-glass/ epoxy and T300/5208 carbon/epoxy composites using the finite element analysis method. The results indicated that both carbon and glass woven fabric-laminated composites showed a similar trend with the composites thickness, i.e.…”

Impact properties of flax fibre-reinforced polymer composites were investigated using two different impact test methods, i.e. drop-weight test and Charpy test. The drop-weight impact tests were conducted with varying drop height. For the drop-weight tests, the perforation energy and the energy absorbed by a specimen are used to study the impact response of the flax fibre-reinforced polymer composite. In a series of Charpy tests, the energy absorbed per unit width of the specimen was investigated. Impact force and Hertzian force were analysed and were found to increase with composite thickness. The ductility index decreased as the composite thickness increased. The failure of flax fibre-reinforced polymer composites started as micro-cracks, progressed to larger cracks and perforation occurred at last. However, the damage to flax fibre-reinforced polymer composites differed with the thickness of the specimens.

The studies have been carried out on the damage initiation behavior of polymer matrix woven fabric composite plates subjected to a transverse central low velocity point impact load. Specifically, the effect of incident impact velocity and impactor mass for the same incident impact energy on the impact behavior has been investigated with a square plate of 150 mm × 150 mm × 6 mm. The material systems considered are: E-glass/epoxy and T300/5208 carbon/epoxy woven fabric composites. Inplane failure of the layers in the form of matrix cracking / lamina splitting and delaminations were the primary objectives of the study. The studies have been carried out using an inhouse Finite Element Analysis code. The inplane failure functions and the interlaminar failure functions have been predicted using quadratic failure criteria. It is observed that the use of incident impact energy alone as a parameter to characterize the impact behavior is inadequate. Instead, the effect of both incident impact velocity and impactor mass should be considered separately.KEY WORDS: impact behavior of composites, low velocity impact, damage initiation, incident impact velocity, impactor mass, incident impact energy.

“…In our earlier studies [12], using nite element analysis, a segmented linear relationship was observed between the peak contact force and the composite plate thickness during low velocity impact. Kim and Kang [13] carried out analytical and experimental transverse impact studies on plain weave glass/epoxy composite plates having various thicknesses.…”

Impact and compression after impact characteristics of a typical plain weave fabric E-glass/epoxy composite have been studied for plates with different thicknesses and the same incident impact energy. Impact studies have been carried out on an instrumented drop weight impact test apparatus. Post-impact compressive strength has been obtained using NASA 1142 test xture. Compressive strength of an unnotched specimen has been obtained using Lockheed test xture with modi ed specimen geometry. Power ts for peak contact force and maximum plate displacement have been given as a function of plate thickness. It is observed that the impact damage area has quasilemniscate shape. Further, damage mechanism has been studied during the post-impact compressive testing. The residual compressive strength as a function of a plate thickness has been obtained.
