Modified Ply Drops for Composite Laminate Materials

摘要

A composite laminate material 310, 510, 710, 910 is disclosed. The composite laminate material 310, 510, 710, 910 includes a plurality of adjacently disposed plies 314, 514, 714, 914. At least one of the plies 314, 514, 714, 914 is configured as a terminated ply 320, 520, 720, 920. Additionally, a ply drop 312, 512, 712, 912 is defined by the terminated ply 320, 520, 720, 920, wherein the ply drop 312, 512, 712, 912is modified to reduce stress concentrations within the composite laminate material 310, 510, 710, 910.
