Title: Reinforced profile members and methods of making the same
Inventor: MOLLER HUBERT
IPC: B29C48/06
Filed: 1986-02-25
Abstract: In a method of manufacturing a reinforced profile member (100) a hollow profile member part (100a) of plastics material or of a plastics-fibre mixture and having at least one hollow chamber (300) extending therethrough is first produced, and after hardening of this profile member part a strengthening hardenable plastics filling or plastics-fibre mixture filling is introduced into the or each chamber. In order to increase the resistance to bending of the profile member, simultaneously with the introduction of the filling into the or each chamber, a core (200) is inserted in such a position that the core is put under tension if the profile member is subjected to a bending stress. The core consists of an inextensible material and can have a filamentary, rod-like, strip-like or other shape. Additional cores (500) may be embedded in the material of the profile member part. <IMAGE>
