To provide a laminated composite structure with interlaminar corrugations to improve impact damage resistance, and a system and a method of forming the same.SOLUTION: 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.SELECTED DRAWING: Figure 6A

    【課題】衝撃損傷耐性を改善するための層間波形を有する積層複合構造体、ならびにそれを形成するシステムおよび方法を提供する。【解決手段】改善された衝撃損傷耐性および改善された強度を有する積層複合構造体が提供される。積層複合構造体は、複合材料の複数の積層された層を有する。複数の積層された層は、複数の積層された層内に形成された1つまたは複数の層間波形を有する。各層間波形は、実質的に正弦波形状の輪郭を有し、形成された積層複合構造体のサイズに応じた深さおよび長さを有する。1つまたは複数の層間波形を有する積層複合構造体は、積層複合構造体の露出した縁部が衝撃力を受けた場合に、露出した縁部において改善された強度および改善された衝撃損傷耐性を有する。【選択図】図6A
