    Abstract

    Methods, techniques, and models available for the measurement or estimation of thermal conductivity, electrical conductivity, thermal diffusivity, thermal expansion, and heat capacity, are reviewed with respect to their applicability to metal matrix composite materials and systems.

    Various factors influencing the choice of method used to obtain reliable properties information are discussed. These include: (a) application and use of the material or system; (b) continuous and discontinuous reinforcement of the matrix; (c) layered and other combination of materials; (d) size and form; (e) anisotropy; and (f) temperature and accuracy requirements.

    Considering the unique problems represented by these materials and systems, recommendations are made regarding the most appropriate means currently available to obtain reliable thermal properties information. Areas are identified where further information and work are required in order to improve existing models and measurement techniques.
