本文通过与常规铺层液滴的比较，实验研究了刮伤铺层液滴对非对称锥形多向碳/环氧层压板低速冲击响应的影响。在能量为12J的锥形区域的平坦一侧施加冲击载荷，然后利用X射线计算机断层扫描(CT)研究铺层擦伤对冲击过程中内部损伤演化的影响。研究发现，与非割伤的传统铺层相比，割伤的铺层滴落降低了端部铺层的应力集中，并有效地防止了纤维断裂。此外，与传统铺层液滴相比，具有刮痕铺层液滴的层合板表现出更少的分层和更低的内部基质开裂程度，因此尽管具有几乎相同的外部损伤，但被认为具有更强的抗损伤能力。
This paper presents an experimental investigation into the effect of scarfed ply drops on the low velocity impact response of asymmetrically tapered, multi-directional, carbon/epoxy laminates, in comparison with that of conventional ply drops. Impact load was applied to the flat side of the tapered region at an energy level of 12 J. The effect of ply scarfing on the internal damage evolution during impact was then investigated using X-ray Computed Tomography (CT) scanning. It was found that the scarfed ply drops reduced stress concentrations at the terminated plies and effectively prevented fibre breakage compared to non-scarfed conventional ply drops. Furthermore, the laminates with scarfed ply drops exhibited less delamination and a lower degree of internal matrix cracking than those with conventional ply drops, and thus were deemed more damage resistant despite having near identical external damage.
