Un material preformado tejido tridimensional (35) que comprende: una pluralidad de tejidos en dirección de urdimbre (22, 24), caracterizado por que dichos tejidos en dirección de urdimbre (22, 24) comprenden una parte sin pinzar (26) y una parte pinzada (28). A three dimensional woven preform, a fiber reinforced composite incorporating the preform, and methods of making thereof are disclosed. The woven preform includes two or more warp steered fabrics. The warp steered fabrics include a darted portion and an un-darted portion. The darted portions of the warp steered fabrics are joined to un-darted portions of one another so as to provide continuous fiber in the circumferential and radial directions of all portions of the preform. An un-darted portion in one steered fabric reinforces a darted portion in the other. The warp steered fabrics can be woven on a loom equipped with a differential take-up mechanism. The warp steered fabrics can be single or multilayer fabrics. The final preform can be a portion of an aircraft window frame.
