Effect of Graphite Nano Particles on Thermal and Mechanical Properties of Short Carbon Fiber Reinforced Phenolic Nanocomposites

Phenolic composites reinforced with short carbon fibers are one of the most usable materials in ultra-high-temperature applications such as thermal protective in aerospace industries. In order to manufacturing an optimum nanocomposite for ultra-high-temperature application in this work polymeric matrix modified with graphite nano particles, and the effect of graphite nano particles on the thermal and mechanical properties of novolac/short carbon fiber composites are investigated. Results showed that the addition of graphite nano particles improved the thermal properties of nanocomposites, however flexural modulus of nanocomposite not showed significant change
