Abstract
A composite structure includes a number of fiber layers. Each fiber layer of the number of fiber layers includes a fiber bundle and a filament layer at least partially covering the fiber bundle. The filament layer includes discontinuous filaments. The discontinuous filaments include at least one of different length filaments, including first length filaments and second length filaments. The first length filaments include a first length and the second length filaments include a second length. The first length is different than the second length. The discontinuous filaments include at least one of different type filaments, including first type filaments and second type filaments. The first type filaments include a first material composition. The second type filaments include a second material composition. The first material composition is different than the second material composition. The composite structure includes a resin binding the number of fiber layers together.
