MOULD FOR PRODUCING FIBRE STRINGERS FOR AEROSPACE STRUCTURES, AND METHOD FOR PRODUCING FIBRE STRINGERS WITH SAID MOULD

摘要

The invention relates to a mould for producing fibre stringers for aerospace structures, and to a method for producing fibre stringers with said mould, comprising a female tool (1) and a male tool (2), by means of which a fibre laminate (13) is formed, which is cut through the middle region in order to form two L-shaped profiles with which a T-shaped profile is formed, the female tool (1) being formed by two facing side assemblies (3) provided with inflatable membranes (6), while the male tool (2) is formed by a central block (7) and two side blocks (8), between which intermediate blocks (9) are inserted, said intermediate blocks being, in turn, provided with inflatable membranes (10), in order to fold and join the two halves of the fibre laminate (13) by means of a combined set of both tools (1 and 2) and inflating the membranes (6 and 10).
