Abstract

Fibre Reinforced Polymer (FRP) is becoming a valid alternative to many traditional heavy metal industries because of its high specific stiffness over the more classical construction metals. Recent trend of more complex geometry of composites is causing increasing difficulty in composite manufacturing. A method to optimize the manufacturing process is thus imposed to ensure and improve the quality of manufactured parts. Because of the irregular 3D shapes of the composites, traditional flat sensor system is becoming unfavorable and nonpractical for monitoring purpose. In this work, the current development status of a deformable microsystem for in situ cure degree monitoring of a glass fibre reinforced plastic is presented. To accommodate the non-flat shape of the composites, the proposal is to interconnect non-deformable functional island, which contains the capacitive sensor for cure degree monitoring, with meander-shaped deformable interconnections. The developed sensor system is able to withstand the manufacturing process where change of pressure and internal strain, thus force exerted on the sensor system, is involved.
基于变形微系统的玻璃钢原位固化度监测
纤维增强聚合物(FRP)因其比刚度高于传统建筑金属而成为许多传统重金属工业的有效替代品。近年来,复合材料几何结构日趋复杂,这给复合材料的制造带来了越来越大的困难。因此,提出了一种优化制造过程的方法,以确保和提高制造零件的质量。由于复合材料的三维形状不规则,传统的平面传感器系统越来越不适合用于监测目的。本文介绍了用于玻璃纤维增强塑料原位固化度监测的可变形微系统的发展现状。为了适应复合材料的非平面形状,建议将包含用于固化度监测的电容式传感器的不可变形功能岛与弯曲形状的可变形互连互连。所开发的传感器系统能够承受制造过程中压力和内部应变的变化,从而涉及施加在传感器系统上的力。
