ABSTRACT:
An inexpensive method of forming close tolerance holes in composites utilizing the B-stage characteristics of those composites. The holes are formed by assembling the composite structure, B-staging the composite material, cutting or drilling undersized holes in the B-staged material, inserting appropriate male forming pins, dies or mandrels in the holes, completing the curing of the composite structure with pins in place and then removing the pins to leave high quality, close tolerance holes in the composite structure.
