Study on Prediction of Compression Performance of Composite Laminates After Impact Based on Convolutional Neural Networks

This paper proposed a method for predicting composite laminates’ compressive residual strength after impact based on convolutional neural networks. Laminates made by M21E/IMA prepreg were used to introduce low-velocity impact damage and construct a non-destructive testing image dataset. The dataset images characterized the impact damage details, including dents, delamination, and matrix cracking. The convolution kernel automatically extracted...
