TL;DR: In this article, the impact energy absorption and damage area due to low-velocity impact on the GFRP composites without wires and stainless steel wire reinforced GFT composites were calculated, and efficiency of absorption was compared with respect to impact velocity and pitch distance.
Abstract: Plain GFRP laminates and stainless steel (SS) wire reinforced GFRP laminates were prepared by hand layup method. The composite specimen reinforced with SS wires placed at various pitch distances was fabricated, and drop-weight impact tests were conducted with velocities of 2.80, 3.13 and 3.43 m/s. The impact damage area was evaluated by using lighting technique, and fracture behaviors were analyzed using scanning electron microscopic images. Impact energy absorption and damage area due to low-velocity impact on the GFRP composites without wires and SS wire reinforced GFRP composites were calculated, and efficiency of absorption was compared with respect to impact velocity and pitch distance.

TL;DR: In this article, the machinability of non laminated composites is investigated by using a special geometry-coated carbide drill (Ratio drill), which was used to examine the influence of process parameters (feed and spindle speed) on quality characteristics (thrust force and torque).
Abstract: Since literature on the machinability of non laminated composites is scarce, an investigation was extended away to study the machinability of thick non laminated Glass Fiber Reinforced Plastic (GFRP) composites and to compare the above with machinability of thick laminated composites. The composites with high fiber weight fraction were drilled with a special geometry coated carbide drill (Ratio drill). Taguchi’s orthogonal array and analysis of variance (ANOVA) were used to examine the influence of process parameters (feed and spindle speed) on quality characteristics (thrust force and torque). The optimum degree of process parameters towards aperture quality was obtained.
