Composite Materials for Aircraft Structures, 2/E (English) by Alan Baker,Stuart Dutton,Donald Kelly.

Description

Composite Materials for Aircraft Structures, 2/E

An introduction to virtually all aspects of the technology of composite materials as used in aeronautical design and structure. This text discusses important differences in the technology of composites from that of metals: intrinsic substantive differences and their implications for manufacturing processes, structural design procedures, and in-service performance of the materials, particularly regarding the cause and nature of damage that may be sustained.
