ABSTRACT

In this study, it is aimed to reveal the effect of deficiencies that may occur during thermoplastic production stages which affects both the low-velocity impact behaviour and mechanical strength of the composite materials. To investigate the low-velocity impact performances of thermoplastic composites with embedded delaminations, specimens were manufactured without delamination materials and by using different embedded delamination materials. Two different delamination diameters were also used so as to investigate the delamination diameters on the impact behaviour of composites. All specimens were subjected to low-velocity impact tests at different energy levels ranging from 10 to 50 J. From the test results, the maximum contact force of the specimens increases with the increment of the delamination diameter.

摘要

在这项研究中，旨在揭示热塑性塑料生产阶段可能出现的缺陷的影响，这些缺陷会影响复合材料的低速冲击行为和机械强度。为了研究具有嵌入分层的热塑性复合材料的低速冲击性能，在没有分层材料的情况下制造了样品，并使用了不同的嵌入分层材料。还使用了两种不同的分层直径，以研究分层直径对复合材料冲击行为的影响。所有试件均进行了10~50 J不同能级的低速冲击试验。从试验结果来看，试件的最大接触力随着分层直径的增加而增加。
