ABSTRACT:
A unidirectional three dimensional fiber structure is provided which does not require weaving, displays a high level of interlayer strength and does not suffer from cracking, and which can also be easily produced with any arbitrary cross-section. A unidirectional three dimensional fiber structure is produced by inserting a plurality of long fibers which have been aligned unidirectionally into an inlet at one end of a cylindrical die with a plurality of needle holes in the peripheral walls thereof, and then performing needlepunch through the needle holes while drawing the plurality of long fibers out from an outlet at the opposite end of the cylindrical die.
