摘要
通过对酚醛树脂基高硅氧预浸料的近红外光谱进行分析,采用化学计量学方法建立了预浸料树脂含量、挥发份含量和预固化度的定量分析模型,研究了光谱预处理方式及光谱区域的选择对定量分析精度的影响。结果表明,用所建立的模型对未知样品预测,树脂含量、挥发份含量和预固化度平均绝对误差分别为0.46%,0.24%和0.42%,可以满足质量检测要求,对生产过程的质量控制具有指导意义。
This paper studied the near-infrared reflectance spectroscopy of glass-fiber reinforced phenolic resin prepreg. The mathematical models between near-infrared spectral parameters and resin content, pre-curing degree and volatile content are built up and the effect factors of the analysis accuracy were investigated using the chemometrics method. It was found that average absolute errors of the resin content, pre-curing degree and volatile content were under 0.74%, 1.18% and 0.26% respectively. The above results show the feasibility of the near-infrared analytic technology for detecting the quality of composite prepregs.
