1. A method of using glass fibers having a tensile strength according to DIN ISO 527-5 of 86.0 to 92.0 GPa, a tensile elastic modulus according to DIN ISO 527-5 of 2600 to 3200 MPa and a softening point according to DIN ISO 7884-1 of 900° C. to 950° C., the method comprising using the glass fibers to increase an impact strength and/or breaking elongation of molded articles made of molding materials comprising thermoplastic polyamides and elastomers;
wherein the method comprises mixing components A) to C) and optionally D):
a) 30.0% to 89.0% by weight of at least one thermoplastic polyamide as component A),
b) 1.0% to 30.0% by weight of at least one elastomer as component B), selected from the group consisting of
b1) copolymers of ethylene with at least one comonomer selected from the group consisting of C3-12-olefins, C1-12-alkyl (meth)acrylates, (meth)acrylic acid and maleic anhydride as component B1),
b2) polyethylene or polypropylene elastomer as component B2),
wherein components B1) and B2) may also be additionally grafted with maleic anhydride,
c) 10.0% to 69.0% by weight of glass fibers having a tensile strength according to DIN ISO 527-5 of 86.0 to 92.0 GPa, a tensile elastic modulus according to DIN ISO 527-5 of 2600 to 3200 MPa and a softening point according to DIN ISO 7884-1 of 900° C. to 950° C. as component C), and
d) 0% to 30.0% by weight of further additives and processing aids as component D),
wherein the percentages by weight of the components A) to D) sum to 100% by weight,
and further comprises extruding, injection molding or blow molding thermoplastic molding material to produce fibers, films, or molded articles made of the thermoplastic molding material.
