Abstract

Journal of Reinforced Plastics and Composites, Ahead of Print.
Carbon fiber-resin composite multi-layer shells are widely used due to their light weight and high strength. However, traditional layup design heavily relies on empirical parameters, making it difficult to match the interlaminar mechanical properties with ...
