This book is intended to advance the technical understanding and practical knowledge of advanced composites, emphasizing the design and manufacture of airframe structures. All aspects of composite design are discussed in a thorough and rigorous fashion which includes guidelines, observations, design factors, pros and cons of design cases, and troubleshooting techniques. Another purpose of this book is to give composite designers and engineers a practical design tool, containing broad data and information gained from past experience and lessons learned in design and fabrication of composite components that can be used to design low cost and weight efficient composite structures with high structural integrity. Composite airframe structural design encompasses almost all the engineering disciplines, and engineers need hands-on information and data that are technically sound and emphasize rational design and technical analysis. This book was written with that need in mind.
