Abstract

Composite materials in this regard represent nothing but a giant step in the ever-constant endeavor of optimization in materials.  The research aims to study the mechanical properties (shock strength and Flexural strength) of composite materials (epoxy resins with phenolic formaldehyde resin) supported by graphite or silica particles or both, and reinforced with Kevlar fibers.

Abstract

The properties of flammability and the effect of zinc oxide with antimony trioxide were examined on the thermal corrosion testing of epoxy resin and formaldehyde. Zinc borate was added to the resin and then reinforced with silica fiber and woven glass fibers (90 ° -0º) with thickness (4 mm). Then expose the system to Acetylene Oxide flame (3500 ° C) directly with different exposures of flame (10 mm, 20 mm), to study flame retardant resistance and protection of the substrate. Animein trioxide was then added to zinc porcine in different quantities (10%, 20% and 30%) to form hybrid flame retardants for hybrid exposure to the same flame temperature and exposure distances. The method of measuring the surface temperature of the flame was used to determine the temperature transferred to the composite material. The results showed that the best exposed distance and a large proportion of protective layer of zinc boron with antimony trioxide was at 30%.
