摘要
本研究调查了用于印刷电子应用的玻璃纤维环氧复合材料的机械性能，包括嵌入式和未嵌入式聚对苯二甲酸乙二酯（PET）基材。这项研究的主要目的是调查层压板中基材位置的影响。在机械测试过程中通过目测观察断裂情况，并在断裂后使用扫描电子显微镜（SEM）进行观察，以确定损坏机制及其传播的差异。拉伸测试表明，嵌入 PET 基材不会影响层压板的极限强度，而弯曲和 SBS 测试表明，根据基材位置的不同，基材集成会使弯曲强度和 ILSS 分别降低 10%和 50%。
Influence of Substrate Location on Mechanical Behaviour of Glass Fibre Composite Materials with Embedded Printed Electronics
This study investigated the mechanical behaviour of glass fibre epoxy composites with and without an embedded polyethylene terephthalate (PET) substrate used for printed electronic applications, with the mechanical behaviour integrity studied under different loading modes: three-point bending, tensile, and short-beam stress (SBS) tests. The main objective of this study was to investigate the influence of the substrate location within the laminate. Fracture profiles were observed by visual inspection during the mechanical tests and scanning electron microscopy (SEM) after failure to identify differences in the damage mechanisms and their propagation. Tensile tests indicated that embedding the PET substrate did not affect the ultimate strength of the laminate, while the bending and SBS tests indicated that the substrate integration reduced the bending strength and ILSS by 10% and 50%, respectively, depending on the substrate location.
期刊介绍：
Applied Composite Materials is an international journal dedicated to the publication of original full-length papers, review articles and short communications of the highest quality that advance the development and application of engineering composite materials. Its articles identify problems that limit the performance and reliability of the composite material and composite part; and propose solutions that lead to innovation in design and the successful exploitation and commercialization of composite materials across the widest spectrum of engineering uses. The main focus is on the quantitative descriptions of material systems and processing routes.
Coverage includes management of time-dependent changes in microscopic and macroscopic structure and its exploitation from the material''s conception through to its eventual obsolescence.
