Patent ID: 8318068

Claim:
A method for joining together constructional parts, which parts are made of a composite material and which parts extend transversely to one another, the method comprising steps of: within a mould, placing i) a first constructional part adjacent and extending transversely to a second constructional part, and ii) a third constructional part adjacent and extending transversely to the second constructional part, wherein the mould with the first, second, and third constructional parts placed therein define a cavity, the cavity has a contour of a final product to be formed, and each of the constructional parts is a composite material comprising fibers and thermoplastic material; subjecting the mould and the first, second, and third constructional parts therein to heat and pressure sufficient to cause i) the thermoplastic material of the first, second, and third constructional parts to melt completely and become fluid with the thermoplastic material flowing out, under pressure, into the cavity including a first connection region between the first and second constructional parts and a second connecting region between the second and third constructional parts, and ii) fusing of the first, second, and third constructional parts in their entirety; and cooling the fused first, second, and third constructional parts to obtain the final product having an outside contour matching the contour of the cavity of the mould.
