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 composite structure, comprising: a ring of stacked unidirectional fiber layers aligned in a first direction, each fiber layer having unidirectional fibers within a binder and having opposing first and second surfaces, wherein the ring has an outer edge formed by the first surface of an outermost one of the fiber layers and an inner edge formed by the second surface of an innermost one of the fiber layers; anda first reinforced region and a second reinforced region, the first and second reinforced regions each including a reinforcing agent infused with a plastic binder, the first and second reinforced regions being non-contiguous with each other and on opposite sides of the ring, the first and second reinforced regions providing enhanced structural strength for the ring,wherein the first and second reinforced regions are defined by a first scrim layer and a second scrim layer, the first scrim layer positioned between the first reinforced region and the ring, the second scrim layer positioned between the second reinforced region and the ring, each scrim layer formed of stacked unidirectional fiber layers aligned in a second direction different than the first direction. 2. The composite structure of claim 1, wherein the reinforcing agent is comprised of carbon fiber. 3. The composite structure of claim 2, wherein the ring of stacked unidirectional fiber layers is substantially free of the carbon fiber. 4. The composite structure of claim 1, wherein the unidirectional fibers are radio transparent. 5. The composite structure as recited in claim 1, wherein the first and second scrim layers prevent substantial migration of the reinforcing agent from the first and second reinforced regions to the ring. 6. The composite structure of claim 1, wherein the reinforcing agent has a higher modulus of elasticity than the ring of stacked unidirectional fibers. 7. The composite structure of claim 1, wherein the reinforcing agent is conductive. 8. The composite structure of claim 1, wherein the first and second reinforced regions each have a thickness of between about 0.05 mm and 0.5 mm. 9. The composite structure of claim 1, wherein the composite structure forms a supportive frame. 10. The composite structure of claim 1, wherein a portion of the composite structure between the first and second reinforced regions is substantially free of carbon fiber. 11. The composite structure of claim 1, wherein the reinforcing agent has a modulus of about 377 GPa. 12. The composite structure of claim 1, wherein the ring is comprised of glass fiber reinforced plastic (GFRP). 13. The composite structure of claim 1, wherein the first and second reinforced regions are each formed of carbon fiber reinforced plastic (CFRP). 14. A composite structure, comprising: a ring having a first side and an opposing second side, the ring comprised of unidirectional fibers aligned in a first direction;a reinforcement system arranged to provide structural strength to the ring, the reinforcement system including a first portion reinforcing the first side of the ring and a second portion reinforcing the second side of the ring, the first and second portions being non-contiguous with each other and each including a reinforcing agent; andan anti-migration system arranged to prevent migration of the reinforcing agent within the ring, the anti-migration system including a first scrim layer positioned between the first portion and the ring, and a second scrim layer positioned between the second portion and the ring, each scrim layer including unidirectional fibers aligned in a second direction different than the first direction. 15. The composite structure of claim 14, wherein the composite structure is a supportive frame for an accessory unit for an electronic device. 16. The composite structure of claim 15, wherein the first and second reinforced regions are on top and bottom portions of the frame. 17. The composite structure of claim 14, wherein the ring is comprised of glass fiber reinforced plastic (GFRP). 18. The composite structure of claim 14, wherein first and second portions of the reinforcement system is each comprised of carbon fiber reinforced plastic (CFRP).
