This book attempts to develop an integrative method that combines the processing and mechanical simulations for z-pinned carbon fiber-reinforced polymer (CFRP) composites. The topics in this book cover experimental characterization, processing modeling, mechanical simulation, and the integrated analysis method for z-pinned CFRP composites. Explanations are made in detail about how to combine the processing induced residual stress and z-pin/composite interfacial debonding with tensile strength, failure mode, and bridging tractions modeling and simulations for z-pinned CFRP composites. This book is considered as a complementary work of existing books about composites mechanics and processing.This book is used as a guideline for graduate students and research engineers who wish to learn the basic modeling techniques in processing and characterizing z-pinned CFRP composites. For reading the book, readers will need the technical background of mechanics and finite element method.
