HEAT TRANSFER IN COMPOSITE MATERIALS

摘要

Nowadays composite materials have extensive industrial applications. The thermalconductivity of composites plays an important role in selecting the optimum materials to meetspecific design requirements in many applications. For example, requirements for moderncomposite structural materials for aerospace applications often include high strength, light weight,easy fabrication, low cost, long durability, and stability against radiation damage and chemicalreactions. Moreover, for certain applications involving the transport ofheat, a tolerable thermal conductivity is necessary [1]. In computer andelectronic applications, the heat produced by modern electroniccomponents is greater and more highly concentrated as a result of higherclock speed, greater power, and reduced size. Providing thermal paths forthe removal of heat by adding fillers with intrinsically high thermalconductivity in the integrated circuit package components is becomingessential [2]. In the oil industry, the thermal conductivity of rocks must beknown to determine heat flow within the earth, and to determine thetemperatures at depths greater than those reached by drilling.
