摘要

摘要: 本文用改进的揭层技术研究含表面缺口层压板的损伤形貌特征.试验了两种即矩形和圆弧形剖面的表面缺口试样.结果表明,改进的揭层技术可以清楚地显示出层压板各层的损伤形貌,因此也给出了含表面缺口层压板损伤形貌特征的一些有意义的结果.

Abstract: In this work an im proved deply technique has been adopted to study the characteristics on damage morphclogy of laminates with a surface notch.Two kinds of surface notch:rectangular and circular are profiles have been tested.The results indicated that the improved deply technique can reveal clearly the damage morphology of the laminates,and on some interesting recognitions of the characteristics of damage morphology have been therefore found.
