Method of producing fabric reinforcing matrix for composites

A method of producing a reinforcing matrix for a composite, comprising the steps of:

• locating on a base a plurality of regulating members arranged in rows that extend in a first predetermined direction;
• weaving yarns between said regulating members to form a lamination having a plurality of yarn layers on said base, said yarn layers having yarns arranged in at least two different directions of said lamination;
• simultaneously removing said lamination and said regulating members from said base;
• collectively forming a plurality of loops corresponding to said plurality of regulating members by collectively replacing said regulating members a row at a time with a corresponding row of vertical yarns, each of said vertical yarns forming one of said loops;
• and
• inserting a locking thread into said plurality of loops of said vertical yarns.

• simultaneously removing said lamination and said regulating members from said base;
• forming a plurality of drive-out spaces in said lamination corresponding to the number of said regulating members by removing said regulating members from the lamination;
• securing a plurality of vertical yarns by means of yarn inserting members corresponding in number to the number of said regulating members arranged in a width direction of said lamination, and simultaneously inserting said yarn inserting members into said lamination through said drive-out spaces in such a way that yarn holding portions of said yarn inserting members come out of the lamination to form a plurality of loops of said vertical yarns;
• and
• inserting a locking thread into said loops held by said yarn holding portions along said yarn inserting member, and extracting said yarn inserting members from said lamination.

• weaving yarns between said regulating members to form a lamination having a plurality of yarn layers on said base, said yarn layers having said yarns arranged in at least two different directions of said laminations;
• simultaneously removing said lamination and said regulating members from said base;
• removing said regulating members from said lamination, and inserting vertical yarns into spaces formed by the removal of said regulating members, such that each of said vertical yarns form a loop;
• and
• inserting a locking thread in a single pass through a plurality of said loops of said vertical yarns.
