Abstract
The microstructural features of fibre-composite materials can be examined using optical or electron microscopy. Micrography can provide values for the principal parameters, the volume fractions of the various components. It also gives information about the relative positions of the fibres. Aramid, carbon and glass reinforced plastics have been examined as monofibre composites and as hybrids. Aramid and nylon cord reinforced rubbers have also been examined. This paper reports the methods of preparation by polishing and etching for the various composites, and the automatic determination of the material microstructure parameters. A simple Apple II microcomputer based system has been assembled to reduce the human subjectivity in the interpretation of micrographs. The computer can accept input from either a graphics tablet or a monochrome television camera through a video interface.
