METHOD FOR LIMITING INTERLAMINAR FATIGUE IN COMPOSITE LAMINATE AND A COMPONENT INCORPORATING THE SAME

Abstract:

In some embodiments, a method of manufacturing composite laminate, including providing a first fibrous material having a plurality of fibers, providing a second fibrous material having a plurality of fibers, disposing the fibers of the first fibrous material in a first polymeric matrix, disposing the fibers of the second fibrous material in a second polymeric matrix, laying up a plurality of the first fibrous material on a rigid structure, laying up the second fibrous material on the rigid structure, wherein the first fibrous material is in contact with the second fibrous material, curing the first polymeric matrix, creating a plurality of baseline layers from the plurality of first fibrous material and the first polymeric matrix, and curing the second polymeric matrix, creating a compliant layer from the second fibrous material and the second polymeric matrix. The compliant layer is stronger than each individual baseline layers.
