دراسة التأثير الحراري على الخواص الميكانيكية لمتراكب هجيني

Abstract

Elastic Modulus (E), Flexural Strength (F.S.), Shear Forces ( ), Impact Strength (I.S.), Surface Indentation, Thermal Conductivity (k) of Composite materials that Consist of Epoxy reinforced with (30%) ratio of Glass fiber and Kevlar fiber and Carbon fiber have been studied A comparison is made between the properties of Composite at different temperature (23, 40, 60, ±2)oC. Volume fraction for all specimens was (30%) and the reinforcement materials were continuous fibers oriented in Woven Roven It was found that elastic modulus for Epoxy increases when the material is reinforced with different type of fiber, where as it decreases when temperature increases. Flexural strength increases with Reinforcement and temperature rise; such as shear Forces ( ) increases with reinforcement and temperature rise. Impact strength and thermal conductivity increases with reinforcement and temperature rise. Surface Indentation for composite material decreases when temperature increases.
