Abstract PA6/sepiolite nanocomposites have been manufactured at different wt% sepiolite loading and a fixed minimum load of a IR absorber additive (CAA). Nanocomposites were characterised and welded with PLA specimens through transmission laser welding technology (TLWT). Resulting welded specimens were also characterised. Experimental data obtained from the characterisations were introduced and processed in a Computer-Aided Engineering (CAE) software to obtain a suitable fracture model based on cohesive zone model (CZM) and capable of predicting the behaviour of the nanocomposite/PLA welds against shear forces. A correlation analysis was performed to assess the goodness of fit between the experimental and simulation data.

PA6/海泡石纳米复合材料与PLA激光透射焊接的实验与数值研究

摘要 PA6/海泡石纳米复合材料已在不同重量百分比的海泡石负载量和红外吸收剂添加剂 (CAA) 的固定最小负载下制造。通过透射激光焊接技术（TLWT）对纳米复合材料进行表征并与 PLA 样品焊接。还表征了所得焊接试样。从表征获得的实验数据被引入并在计算机辅助工程 (CAE) 软件中处理，以获得基于内聚区模型 (CZM) 的合适断裂模型，并能够预测纳米复合材料/PLA 焊缝抵抗剪切力的行为。进行相关分析以评估实验和模拟数据之间的拟合优度。
