Abstract
A thermoplastic resinous composite material has the good flowability of a meltage of the composite material during a molding process and can provide not only the excellent tensile strength, the excellent flexural strength, the excellent flexural elasticity and the excellent H.D.T of a product molded using the composite material but also provide the better impact resistance which can not be achieved by a composite material of the art. The thermoplastic resinous composite material is made from a mixture mainly consisting of mica, a wood cellulose filler and a thermoplastic resin. The mix proportion of mica, the wood cellulose filler and the thermoplastic resin is 10-50 weight by parts 10-43 weight by parts: 70-82 weight by parts.
Claims16
A thermoplastic resinous composite material made from a mixture mainly consisting of mica, a wood cellulose filler, and a granulous thermoplastic resin, characterized in that:
- 10-50 weight by parts of mica,
