ABSTRACT
Composites are materials which have characteristics that cannot be obtained from a single material alone but which can be obtained by combining and synthesizing various materials that are different in nature (e.g., polymers, inorganic powders, metals, and oxides of them and their fibers) and configuration. An interfacial contact is thus inevitably between the different materials, and it is well known that the characteristics sought for in the material are strongly influenced by the bonding at the contact surface (interface). To derive full performance from the composites, many unknown problems concerning the nature of the interface between different materials, and the behavior and reaction at the interface, must be clarified and solved.
