Abstract
A quasi-isotropic three-dimensional preform and a method of making thereof are disclosed. The preform includes a plurality of woven elements that are braided with each other. The woven elements have one or more integrally woven stiffeners or walls in a direction perpendicular to the plane of the woven element. The preform may be used in forming a fiber reinforced composite.
Claims17
A quasi-isotropic three-dimensional preform comprising:
- at least three individual woven elements braided with each other to form a preform skin,
- wherein each of said individual woven elements is a fabric strip formed by interweaving a plurality of warp and weft yarns or fibers, each woven element including two or more integrally woven stiffeners or walls in a direction perpendicular to the plane of the preform skin,
- wherein the at least three individual woven elements are braided with each other such that two integrally woven stiffeners from each of three individual woven elements form a hexagonal cell perpendicular on the preform skin, and
- wherein said two or more integrally woven stiffeners are formed from the individual woven elements.
