Abstract: The outlines of the new military airplane structural strength specifications for composite structures and the differences from those of metallic structures are presented in this paper. These characterizations are: the material and process requirements based on the diversity of property characterization and synchronous formation of materials and structures; the determination methodology of design allowables based on considering the influence of initial flaw/damage on static structural strength; static strength design and verification considering specially the hydro-thermal influence; durability design and verification based on the concept, in which static strength design could cover fatigue design, and consideration of impact damage resistance; damage tolerance design and verification based on the main flaw/damage type of impact damage and damage non-propagation concept; and the structural verification test based on Building-Block Approach consisting.

Key words: composites, strength specification, static strength, durability, damage tolerance, structural verification test
