Abstract
The present invention relates to lightweight components of hybrid design, also termed hybrid component or hollow-chamber lightweight component, composed of a parent body which is composed of galvanized iron and which is reinforced by means of thermoplastics and is suitable for the transmission of high mechanical loads.
Claims12
A lightweight component comprised of a parent body of galvanized iron and having reinforcing structures, where the reinforcing structures are securely connected to the parent body and are formed of moulded-on thermoplastic polymer compositions, wherein the thermoplastic polymer compositions comprise polyamide moulding compositions which comprise from 99.99 to 10 parts by weight of at least one aliphatic, semicrystalline, thermoplastic polyamide, and the galvanized iron is pretreated by a process selected from the group consisting of acid treatment, soda treatment, amine treatment, anodic treatment, base treatment and laser treatment.
A process for the production of a lightweight component of hybrid design composed of a parent body which has reinforcing structures and which is composed of galvanized iron, where the reinforcing structures are securely connected to the parent body and are formed of moulded-on thermoplastic, wherein the thermoplastic comprises polymer moulding compositions of polyamide, and these comprise from 99.99 to 10 parts by weight of at least one aliphatic, semicrystalline, thermoplastic polyamide, and secure interlock connections are formed between parent body and the thermoplastic reinforcing structures by shaping processes in a shaping mould, by way of the galvanized iron surface of the parent body, the surface of which has been pretreated by a process selected from the group consisting of acid treatment, soda treatment, amine treatment, anodic treatment, base treatment and laser treatment.
Motor vehicles, rail vehicles, aircraft, ships, sleds or motor scooters, comprising a lightweight component of hybrid design formed of a parent body of galvanized iron with moulded-on thermoplastic, wherein the thermoplastic is polyamide.
