Composite preforms

Abstract

A preform for a composite may include a plurality of fibrous layers consolidated together and forming the preform extending along a longitudinal axis. The plurality of fibrous layers includes at least one first fibrous layer and at least one second fibrous layer. The at least one first fibrous layer includes a plurality of first segments, and the least one second fibrous layer includes a plurality of second segments. At least one first segment of the plurality of first segments includes a plurality of reinforcing fibers extending at an angle −α relative to a radial direction extending from the longitudinal axis. At least one second segment of the plurality of second segments includes a plurality of reinforcing fibers extending at an angle +α relative to the radial direction. α is greater than 0° and less than 90°.
