摘要:

基于纤维铺放成型生产的复合材料层合板所出现的翘曲缺陷,运用合理表征方法,并运用形态学原理搭建无接触视觉测量平台对其进行识别,通过设计不同工艺参数对其进行优化,并探究翘曲度与拉伸性能的关系,并进一步对翘曲缺陷进行优化。结果表明,无接触视觉测量平台可以精准识别翘曲度,热风枪温度由300 ℃升到500 ℃,翘曲缺陷减小;翘曲度与拉伸性能呈负相关。通过加热模具的措施可以进一步优化翘曲。

Abstract:

In this paper, the warping defects appearing in composite laminates produced by fiber placement was addressed. A suitable characterization method was adopted and a non⁃contact visual measurement platform based on morphological principles was established to identify these defects. Through the design of different process parameters, the optimization for solving the detect problem was performed. The relationship between warping degree and tensile performance was explored to further optimize the warping defects. The experimental results indicate that the non⁃contact visual measurement platform could identify the warping degree accurately. The warping defects were reduced with an increase in the heat gun temperature from 300 to 500 ℃. There is a negative correlation between warping degree and tensile performance. The warping can be further optimized by heating the mold.

Key words: thermoplastic composite material, automated fiber placement, warpage, canny edge detection
