Description

This book is aimed at those who are considering building or maintaining a composite aircraft, as well as those who want to work with and design using composite materials. It is aimed at both beginners and at those who have an engineering background but are new to the world of composites. This book is not specific to any particular aircraft, but explores the techniques used in most composite aircraft construction, taking the reader all the way from mixing resin through to structural and design considerations. Various layup techniques, core construction and materials, bonding, tools, mold making, curing concerns, and material properties are all explained. Repairing damaged structures is covered, as is designing proper load transfers. Basic stress analysis and comparisons to metal structures is explored. Fiber orientation, fiber volume content, and structure weight is discussed.
