摘要/Abstract

摘要： VAT(Variable Angle Tow Placement)是当前国际先进的计算机控制纤维预制体成型工艺。本文对VAT工艺中的三种多发性制品缺陷及缺陷程度进行试验设计,并采用VARI工艺制备10种CFRP板制件。运用超声相控阵C扫描、SEM进行宏观检测和细观表征。对CFRP制件进行纵向拉伸与压缩试验,研究了变角度牵引铺缝对CFRP板材力学性能的影响,对进一步完善VAT工艺,以及质量体系建立和效益提升十分有益。

Abstract: VAT (Variable Angle Tow Placement) is an international advanced computer-controlled fiber preform forming process of fiber reinforced plastics. In this paper, three kinds of multiple product defects and defect degree of VAT process were designed, and 10 kinds of CFRP plates were made by VARI process. Ultrasonic phased array C-scan and SEM were used for macroscopic examination and microscopic characterization. The longitudinal tensile and compression tests of CFRP were carried out to study the effect of unidirectional laying defects on the mechanical properties of CFRP sheet. It is very beneficial for VAT process to be further improved, quality system to be established and benefit to be improved.

Key words: CFRP, VAT, defects, mechanical properties
