Abstract
The present invention refers to a fiber reinforced polymer composition comprising a polypropylene, carbon fibers and a polar modified polypropylene as coupling agent as well as to an article comprising the fiber reinforced polymer composition.
Claims15
A fiber reinforced polymer composition comprising:
- (a) from 65 to 98.9 wt. %, based on the total weight of the fiber reinforced polymer composition, of a polypropylene (PP);
- (b) from 1 to 10 wt. %, based on the total weight of the fiber reinforced polymer composition, of carbon fibers (CF);
- and
- (c) from 0.1 to 10 wt. %, based on the total weight of the fiber reinforced polymer composition, of a polar modified polypropylene (PMP) as coupling agent,
- wherein the polar modified polypropylene (PMP) comprises groups derived from polar groups in an amount of from 1 to 5 wt. %, based on the total weight of the polar modified polypropylene (PMP);
- and
- wherein the carbon fibers (CF) are in the form of a non-woven fabric.
