Book Description
This report describes the approach followed to develop a database for mechanical properties of textile composites. The data in this database is assembled from NASA Advanced Composites Technology (ACT) programs and from data in the public domain. This database meets the data documentation requirements of MIL-HDBK-17, Section 8.1.2, which describes in detail the type and amount of information needed to completely document composite material properties. The database focuses on mechanical properties of textile composite. Properties are available for a range of parameters such as direction, fiber architecture, materials, environmental condition, and failure mode. The composite materials in the database contain innovative textile architectures such as the braided, woven, and knitted materials evaluated under the NASA ACT programs. In summary, the database contains results for approximately 3500 coupon level tests, for ten different fiber/resin combinations, and seven different textile architectures. It also includes a limited amount of prepreg tape composites data from ACT programs where side-by-side comparisons were made. Delbrey, Jerry Langley Research Center NAS1-19348; RTOP 505-63-10-10...

Book Description
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. The English translation of this book from its Chinese original manuscript was done with the help of artificial intelligence (machine translation by the service provider DeepL.com). A subsequent human revision of the content was done by the author.
