Abstract
A fiber-reinforced molded plastic part, a process for its manufacture and a use. The fiber-reinforced molded plastic part consists of a plastic matrix with natural fibers particularly arranged in a uniformly distributed manner in the plastic matrix. The plastic matrix has at least two mutually mixed polymers, of which one is a biopolymer and the other is a polymer which is at least largely resistant to biological stress.
Claims11
A fiber-reinforced molded plastic part, the part comprising a plastic matrix with embedded natural fibers, the plastic matrix comprising:
- at least one biopolymer selected from the group consisting of thermoplastic starch and granular starch;
- and
- at least one thermoplastic polymer selected from the group consisting of poly(imino(1-oxyundecamethylene));
- poly(hexamethylene sebacamide);
- poly((e-caprolactam) co(hexamethylene azelaic amide));
- polyamide of azelainic acid;
- polyurethane with a polyol constituent of reproducible raw materials;
- cellulose propionate, and cellulose ether ester,
- wherein the at least one biopolymer forms a disperse phase in the plastic matrix and the at least one thermoplastic polymer forms a continuous phase thereby enclosing the at least one biopolymer.
A fiber-reinforced molded plastic part, the part comprising a plastic matrix with embedded natural fibers, the plastic matrix consisting of:
- at least one biopolymer selected from the group consisting of thermoplastic starch and granular starch;
- and
- at least one thermoplastic polymer selected from the group consisting of poly(imino(1-oxyundecamethylene));
- poly(hexamethylene sebacamide);
- poly((e-caprolactam) co(hexamethylene azelaic amide));
- polyamide of azelainic acid;
- polyurethane with a polyol constituent of reproducible raw materials;
- cellulose propionate, and cellulose ether ester,
- wherein the at least one biopolymer forms a disperse phase in the plastic matrix and the at least one thermoplastic polymer forms a continuous phase thereby enclosing the at least one biopolymer.
A fiber-reinforced molded plastic part, the part comprising a plastic matrix with embedded natural green flax fibers, the plastic matrix comprising:
- at least one biopolymer selected from the group consisting of thermoplastic starch and granular starch;
- and
- at least one thermoplastic polymer selected from the group consisting of polyamide, polyurethane, cellulose propionate, and cellulose ether ester,
- wherein the at least one biopolymer forms a disperse phase in the plastic matrix and the at least one polymer forms a continuous phase thereby enclosing the at least one biopolymer.
