Evaluation method for delamination degree and interfacial strength of composite-material

摘要

The present invention relates to a method for evaluating the degree of delamination and interfacial strength of a composite material, which comprises the following steps of: applying external forces to a composite material sample; arranging the composite material sample between a light source and a photographing device; obtaining an image by allowing the photographing device to shoot light which has passed through the composite material sample; and evaluating the degree of delamination of the composite material by analyzing the obtained image. Therefore, interfacial strength of the composite material can be detected by using a simple method.
