TL;DR: In this article, repeated drop weight impact tests were carried out on advanced composites (glass, carbon, kevlar in epoxy matrix - LY 556, HT 972) using an instrumented impact test machine (DYNATUP 8250).

TL;DR: In this article, experimental studies were carried out on two different glass-epoxy composites (one room temperature curing epoxy-amine system and the other, an elevated temperature cured epoxyamine system) subjected to two different curing techniques (thermal and microwave), in order to investigate the effects on their thermomechanical properties.

TL;DR: The results of the studies carried out on composites with three distinctly different particulate fillers, representing ductile (Cu and Al), brittle (SiC), and soft (Gr) type of materials regarding the mechanical properties, showed that the tensile and flexural strength of the particulate composites degraded with filler loading, whereas the modulus increased with the filler loading for the range of filler contents considered.

TL;DR: In this article, an investigation into the mechanical behavior of microwave-cured glass-epoxy composites is carried out and the results are compared with those of thermally cured composites.

TL;DR: In this article, the optimum core to skin weight ratios for maximum stiffness and strength of the sandwich panels were experimentally found to be 2.04 and 0.96 as against the theoretical values of 2.0 and 1.0.
