METHOD FOR MANUFACTURING A T-SHAPED COMPOSITE PART BY RESIN-TRANSFER MOULDING

摘要

The invention relates to a method for manufacturing a T-shaped composite part by resin-transfer moulding, which includes the steps involving: creating a preform having a substantially planar stack (A) of plies and having two L-shaped stacks (B, C) of plies; placing said preform such that said L-shaped stacks L (B, C) meet between two cores (M1, M2) of a resin-transfer moulding tool (M); inserting and removing fibres through said planar stack (A) in a direction perpendicular or quasi-perpendicular to said stack (A) and such as to form loops (b) inside the portions (81, 82) of said L-shaped stacks (B, C) that are substantially perpendicular to said planar stack; closing the moulding tool (M); injecting the resin into the moulding tool (M); and heating the moulding tool (M) in order to cure the resin.
