This book reports thermo-mechanical coupling constitutive equations and impact damage distributions of 3-D braided composite materials under impulsive loadings, in multidisciplinary fields among mechanical engineering, textile engineering and impact dynamics. The 3-D braided composite is one of the unique textile composites with integrated braided preform structure. Currently the 3-D braided composite has been rapidly applied to aerospace, automotive and medical engineering because the materials could realize the integration of material structure to manufacture complex structural parts and reduce the number of assembly connections. This book presents a thermo-mechanical coupled multiscale geometrical model of the 3-D braiding composite beams and tubes for analyzing damage mechanisms under various impact velocities. Impact deformation and damage morphologies have been described both in experimental observations with high speed cameras, micro-CT and finite element analyses. All the impact damages are shown in figures for unveiling the relationships between microstructure and failure modes. This provides a vivid way for how to design braided structures with high impact damage tolerance. The book is intended for graduate students who are interested in composite materials and mechanics, researchers investigating on impact dynamics of composite structure design, and engineers working on impact-proof structure design.
