Abstract

ABSTRACT High-speed impact behaviour of composite sandwich panels reinforced by nano-SiO2 has been studied in the present article. The sandwich panels were manufactured by glass/fibre epoxy composite face sheets and an M-shaped core using the vacuum-assisted resin transfer moulding (VARTM) method. To enhance the mechanical strength of the matrix, especially impact resistance, the nanoparticles were added to the resin epoxy matrix as filler. A scanning electron microscope (SEM) was utilised to observe the microscopic structure of the composites. The experimental results indicated that adding 1–3 wt-% of nano-SiO2 into the matrix remarkably increased the impact resistance of the composite. In order to validate the results, the experimental data were compared to the finite element models, and good agreement was observed.

基于实验和有限元方法的格芯GFRP增强夹层结构高速冲击分析

本文研究了纳米sio2增强复合材料夹芯板的高速冲击性能。夹层板由玻璃/纤维环氧复合材料面板和m型芯板制成，采用真空辅助树脂转移模塑(VARTM)方法。为了提高基体的机械强度，特别是抗冲击性能，将纳米颗粒作为填料添加到树脂环氧树脂基体中。利用扫描电子显微镜(SEM)观察了复合材料的微观结构。实验结果表明，在基体中加入1 ~ 3 wt-%的纳米sio2，可显著提高复合材料的抗冲击性能。为了验证实验结果，将实验数据与有限元模型进行了比较，结果吻合较好。

期刊介绍： Plastics, Rubber and Composites: Macromolecular Engineering provides an international forum for the publication of original, peer-reviewed research on the macromolecular engineering of polymeric and related materials and polymer matrix composites. Modern polymer processing is increasingly focused on macromolecular engineering: the manipulation of structure at the molecular scale to control properties and fitness for purpose of the final component. Intimately linked to this are the objectives of predicting properties in the context of an optimised design and of establishing robust processing routes and process control systems allowing the desired properties to be achieved reliably.
