Abstract: A pre-form and a method of preparing pre-forms are provided. The pre-forms comprise a resin and at least three layers of oriented fiber tows. The pre-forms comprise fiber tows instead of the traditional prepregs to enhance rearranging of resin and/or fibers during subsequent processing as well as provide greater freedom, a price reduction and/or a reduction of waste.
