Abstract:
Environmentally correct composites, made from natural lignocellulosic fibers (FNL), are among the most researched and applied today. Among the FNLs, we highlight the Rami fibers (Boehmeria nivea), which arise as an alternative to synthetic fiber fabrics in multilayer armor systems, for use in ballistic protection vests, because they are lightweight, low cost and environmentally correct. In the present work, the mechanical behavior of epoxy matrix laminated composites reinforced with ramie fabric was investigated through tensile tests, under different curing conditions. Laminated composites were fabricated in a metal mold under vacuum conditions. The fractured specimens were analyzed in SEM and the results were evaluated aiming at some tensile properties with the incorporation of ramie fabric, aiming at their subsequent application in ballistic armor.
