초록

A stiffened composite is provided exhibiting multi-directional reinforcement with continuous long fibers. The composite has a substrate and serpentine stiffeners adhered thereto. The stiffeners merge toward, join with and diverge from adjacent stiffeners to provide a stiffener matrix on the substrate. The serpentine stiffener permit the matrix to exhibit multi-directional reinforcement with the continuous long fibers within the serpentine ribs. The composite structures are useful as aircraft bypass ducts, and as other composite products.

청구항

[ We claim:] [1.] A composite structure comprising:(a) a tubular substrate, and(b) a plurality of stiffeners adhered to said substrate, wherein each of said stiffeners is a serpentine stiffener which longitudinally merges toward, joins with and then diverges from an adjacent stiffener, wherein each of said serpentine stiffeners comprises a plurality of reinforcing fibers extending longitudinally within said serpentine stiffener. [9.] An aircraft engine comprising:(a) a bypass duct comprising:(i) a tubular substrate,(ii) a plurality of fiber reinforced se...
