Granulat av fiberförstärkt termoplast

摘要

In a granular material comprising fibre-reinforced thermoplastics, a multiplicity of individual filaments of the reinforcing fibres (for example glass) are arranged in parallel in a matrix of thermoplastic material (for example polypropylene). The fibre 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 greater than 100 Pa.s, the diameter of the granules (measured perpendicular to the fibre direction) is from 1.7 to 5 mm, and the diameter:length ratio of the granules is from 0.4 to 1.66.
