Abstract:

Fiber-reinforced structures for use in forming support structures and electronic device housing members may include multiple types of fiber. A first portion of the structures formed from a first type of fiber such as glass fiber may be radio transparent. A second portion of the structures formed from a second type of fiber such as carbon fiber may be more rigid than the first type of fiber and may be radio opaque. The second portion of the structures may be used to selectively add strength to the fiber-reinforced structures. The first portion of the structures may be used to maintain radio transparency for compatibility with wireless electronic device operations. The fiber-reinforced structures may be formed by rolling a sheet of prepreg material that includes a first area with the first type of fiber and a second area with the second type of fiber.
