Hybrid composites have great potential for specific strength and stiffness, effective in aerospace industries, submarines, light-weight automotives. The mechanical adhesiveness of hybrid laminates can be enhanced by use matrix materials different ratios epoxy resin hardener. Gentle hardener the fabrication alter tensile modulus, bonding between fabric. Spectacular progress has been achieved sel...

The fracture of materials is a catastrophic phenomenon of considerable technological and scientific importance. Here, we analysed experiments designed for industrial applications in order to test the concept that, in heterogeneous materials such as fiber composites, rocks, concrete under compression and materials with large distributed residual stresses, rupture is a genuine critical point, i.e...

Militaries may have found the next technology advancement, a replacement in body armor. Graphene is a single atomic layer of graphite, which is composed of a hexagonal lattice of carbon atoms. It exhibits properties of extreme strength and is extremely lightweight. Engineers have begun testing this material’s successfulness in bulletproof vests. We will delve into the strengths and weaknesses o...

there is a worldwide interest in using fibers of different types in concrete mixtures. in this regard, as the use of pet fibers has gradually increased during the last decade, this study aims to investigate the effects of pet fibers on the mechanical properties of hardened concrete and the workability of fresh concrete. to this end, different contents of pet fibers (pc= %0, %0.5, %1 and %1.5) a...
