摘要

Delamination factor is one of the most important factors evaluating the surface integrity of carbon fiber-reinforced polymer laminates. The value of the delamination factor in edge trimming of carbon fiber-reinforced polymer laminates controlled the acceptance or rejection of the machined component. Therefore, using a reasonable and efficient approach to characterize the delamination region is very beneficial. However, the conventional delamination factor is a one-dimensional evaluation method, and hence, it cannot distinguish the delamination extent of carbon fiber-reinforced polymer laminates after edge trimming. The contribution of this work is to present a novel assessment approach to characterize the cutting-induced delamination using a milling cutter and compare it with the conventional delamination factor. The experimental results indicated that the delamination factor based on area assessment method is suitable to evaluate the delamination extent at the top layer after edge trimming.
