Method of reinforcement of an open hollow member, in particular made of metal for a vehicle

摘要

The method involves placing a number of reinforcing profiles (2) in the hollow profile structure (1), and fixing the profiles to the opposite inner wall area (6). The geometry tolerant reinforcing profiles have thermoplastic layer (8), which is used as a casing or outer sleeve. Each profile has an over-dimension in the range of 0.4 to 2.0 millimeters between formed fixing positions at the opposite ends. Each reinforcing profile of the open hollow profile structure of the component, locally preheated at the predetermined inner wall area, is pushed in, with a predefined contact pressure. The reinforcing profile is made of reinforced or unfilled polybutylene teraphthalate (PBT), filled polyamide or 30 percent glass-fiber filled polyamide (PA-30GF). An independent claim is also included for an open hollow profile structure of a component, particularly a metal component.
