3D打印柔性可拉伸离散功能梯度衬底的界面结构设计
Interface structure design of 3D printing flexible stretchable discrete functional gradient substrate
摘要
Abstract
To address the challenges of interfacial separation and poor tensile properties in discrete functional gradient sub-strates,this study proposed a novel substrate structure based on interface design.Using PDMS-based materials as an ex-ample,functional gradient flexible substrates were fabricated via extrusion-based 3D printing.Six distinct interface struc-tures were evaluated for their tensile properties,with the island structure demonstrating the most effective suppression of interfacial delamination.Orthogonal experiments were conducted to optimize the island structure parameters,using ten-sile ratio as the key performance metric.The optimal configuration was determined as follows:4 islands per unit length,an island-to-bridge length ratio of 1,a width ratio of 1.75,and an edge margin ratio of 0.07.The results indicated that the island structure significantly enhanced interfacial cohesion,improving the tensile ratio by 1.82 times compared to con-ventional designs.关键词
