ABSTRACT:
In granules of fiber-reinforced thermoplastic material, a multiplicity of individual filaments of the reinforcing fiber (e.g. glass) are arranged in parallel in a matrix of the thermoplastic material (e.g. polypropylene). The fiber length corresponds to the granule length and is in the range from 3 mm to 8 mm. The melt viscosity of the thermoplastic material is above 100 Pa.s, the diameter of the granules (measured perpendicular to the fiber direction) is 1.7 to 5 mm and the ratio diameter:length of the granules is 0.4 to 1.66.
