METHODS FOR FORMING FIBER COMPOSITE STRUCTURES

摘要

An accessory unit includes a front flap and a rear cover. The rear cover includes a recessed portion that defines a chamber and a frame that extends about an opening of the chamber. The chamber is configured to receive a consumer electronic device, and the frame is configured to hold the consumer electronic device therein. For example, the frame may define a multi-sided cross-section with an inner edge thereof configured to engage a chamfered edge of the consumer electronic device. The front flap may include segments formed from panels with folding regions therebetween, which allow the front flap to fold. Further, an end region of the front flap hingedly couples the front flap to the rear cover, such that the front flap may be moved between open and closed configurations.

1. A method of forming a composite structure, the method comprising:
forming a ring having a first set of fibers arranged in a first direction, the ring having a first side and opposing second side; forming a first reinforcement structure and a second reinforcement structure, each reinforcement structure including a reinforcing agent and having a surface with a scrim layer coupled thereto, each scrim layer having a second set of fibers; and reinforcing the ring by coupling the first reinforcement structure to the first side of the ring and the second reinforcement structure to the second side of the ring such that the first reinforcement structure is non-contiguous with the second reinforcement structure, wherein is positioned between the first reinforcement structure and the ring and a second scrim layer is positioned between the second reinforcement structure and the ring, wherein the second set of fibers are arranged in second direction different than the first direction of the first set of fibers preventing migration of the reinforcing agent into the ring.
