Preform Stitching

Increasing demands for more complex shaped preforms and, in some cases, additional Z-axis fiber reinforcement has stimulated the advancement of preform stitching processes at Fiber Innovations. Combinations of braided fabrics or braided and woven fabrics are stitched to net shape prior to insertion into the resin transfer mold.

In addition to producing preforms of complex shapes, stitching also provides a means of joining multiple components in the fabrication of an assembly while providing additional structural reinforcement.

The stitching process at Fiber Innovations has been successfully employed for the fabrication of a variety of complex shaped preforms such is “I”, “J” and “T” section stiffeners.
