  • Publication number: 20160031182
    Abstract: According to various embodiments, a carbon fiber structure is presented. The carbon fiber structure may address loads presented to an engine component in various directions. For instance, non-planar surfaces of a composite comprising a structure disclosed herein may achieve enhanced stiffness and/or strength. Thus, delamination of elements comprising a structure disclosed herein may be reduced. A three dimensional weave of carbon fiber elements through-thickness may provide enhanced strength to the composite material.
