3D Woven Casing Preform With Deployable Stiffeners for Vibration Loads

The patent integrates reinforcement regions directly into the fibrous web structure used to manufacture the casing. The reinforcement zones are woven into the same fibrous web that forms the casing body, eliminating the need for separate reinforcement components and their associated attachment steps. This merging of functions resolves the contradiction by improving mechanical strength through integrated reinforcement while reducing device complexity by removing additional connection mechanisms.

The reinforcement regions are prepared and positioned within the fibrous web during the manufacturing process itself, before the casing is completed. The fibrous web with integrated reinforcement zones is wound around the mandrel and then impregnated with matrix material in a single continuous process. This preliminary integration of reinforcement structures eliminates subsequent attachment operations, resolving the contradiction between strength improvement and complexity reduction.

The patent combines the reinforcement regions with the main casing structure by integrating them into the same fibrous web. This single integrated web is wound around the mandrel and impregnated with matrix material in one continuous manufacturing process, eliminating the need for separate attachment operations. This merging approach improves mechanical strength while maintaining ease of manufacture by simplifying the production process.

The patent uses a fibrous web composed of composite material structure with reinforcement zones integrated into the weave pattern. The fibrous web itself is a composite structure that provides both the casing body and reinforcement regions. This composite material approach allows simultaneous improvement of mechanical strength and ease of manufacture by enabling both functions to be achieved through a single material system and manufacturing process.
