Abstract: The present invention relates to a process for the production of a structured grain on the surface of a thermoplastic having continuous-fiber reinforcement by a textile sheet, where a mixture of at least one fiber material and of at least one thermoplastic is heated and pressed in a mold to a temperature above the softening point of the thermoplastic, where a structured grain has been applied on the internal side of the mold. The at least one fiber material comprises continuous fibers and takes the form of a regularly arranged textile sheet. The textile sheet and the structured grain on the internal side of the mold are oriented in relation to one another in a manner such that during the pressing procedure the textile sheet and the structured grain on the internal side of the mold are mutually superposed.

Abstract: A muscle trainer comprising curved, elongate spring elements is disclosed. The spring elements are arranged with facing concave sides and include end areas formed at each of the ends of the spring elements. The muscle trainer includes a first joint element being formed at a first end area of each spring element and a second joint element being formed at a second end area of each spring element.

Abstract: The invention relates to processes for the production of a composite component via multicomponent injection molding, where the composite component comprises a main body composed of a thermoplastic and an external layer composed of a foamed thermoplastic. The main body is produced via injection molding and subsequent hardening of the thermoplastic. A mixture of the foamed thermoplastic and a chemical blowing agent is injected onto the main body, subsequently hardened in the same injection mold, and foamed by heating. The composite component is solidified via cooling. The foamed thermoplastic is at least one polyamide whose modulus of elasticity is from 1 MPa to 250 MPa in the entire temperature range from 70° C. to 180° C. The chemical blowing agent is in non-polymerized form.
