  • Manufacture of flowable composite particulate material
    Patent number: 4244903
    Abstract: The moldings are manufactured from synthetic thermoplastics, from non-thermoplastic fibrous flakes, which are available in an uncoated or incompletely coated state, and from optionally admixed fillers. The fibrous flakes and the thermoplastic material are mixed under the action of pressure and heat to produce a precompacted composite material, in which the fibrous flake material constitutes about 65% or more by volume of the composite material, and the latter is then extruded and is subsequently finally shaped and finally compacted at the same time.
