LAMINATED COMPOSITE STRUCTURES WITH INTERLAMINAR CORRUGATIONS TO IMPROVE IMPACT DAMAGE RESISTANCE, AND SYSTEM AND METHOD OF FORMING THE SAME

摘要

There is provided a laminated composite structure having improved impact damage resistance and improved strength. The laminated composite structure has a plurality of stacked layers of a composite material. The plurality of stacked layers has one or more interlaminar corrugations formed within the plurality of stacked layers. Each interlaminar corrugation has a substantially sinusoidal shaped profile and has a depth and a length dependent on a size of the laminated composite structure formed. The laminated composite structure with the one or more interlaminar corrugations has improved strength and improved impact damage resistance at an exposed edge of the laminated composite structure, when the exposed edge is subjected to an impact force.
