Random Glass Mat Composites – Materials with Macrostructure
An important class of random glass mat reinforced thermoplastics (GMTs), also called random continuous glass fiber thermoplastic composites, comes in the form of thermoplastic sheets containing non‐woven, random continuous glass fibers. The process for making GMTs induces a preferential alignment of the glass mat fibers along moving direction – called the machine direction – resulting in different material properties along the machine and cross‐machine directions. GMT parts are formed by placing hearted blanks of the GMT material inside matched molds in a predetermined pattern and thermostamped. The nonuniform distribution of glass in GMT, which makes the material thermostampable, causes the material to be both anisotropic and nonhomogeneous. As a result, elastic moduli measured by standard ASTM tests show a significant amount of scatter, and the results appear to depend on the specimen size. Information on tensile test and three‐point flexural test is provided.
