Three-dimensional woven preforms are curved and have continuous fibers in the direction of curvature and wherein the base of the preforms is curved with the warp fibers continuous across the length of the preform and some of the warp fibers are longer than other warp fibers.

Curved preform and method of making thereof

Embodiments for clamps and shaping clamp systems are disclosed herein and drawn to such applications as, including but not limited to, an apparatus and method for forming three-dimensional woven preforms that can be curved and have continuous fibers in the direction of curvature. Embodiments of the clamps may include an upper clamp, and a lower clamp of complementary shape and mateable with the upper clamp, with the clamp being configured to receive a fabric therebetween.

Disclosed is an apparatus and method for forming three-dimensional woven preforms that can be curved and have continuous fibers in the direction of curvature. Also disclosed are woven preforms formed thereby.
