摘要： In a first aspect, there is a method (300) of making a specimen with a predetermined wrinkle defect, the steps including orienting (303) a composite material around a layup tool (302) at a wrap angle to form a closed loop; and generating (309) at least one wrinkle with a predetermined characteristic in a portion of the closed loop to form a specimen. The predetermined characteristic is at least one of the following: wrinkle location, an outward wrinkle, an inward wrinkle, a wrinkle width, a wrinkle height, and a wrinkle length. In another aspect, there is a method (400) of determining allowable defects for a composite component.

摘要： A tiltrotor aircraft (10) includes a fuselage (12), a wing member (18) extending from the fuselage, an engine disposed relative to the wing member and a proprotor (26) mechanically coupled to the engine. The proprotor includes a plurality of proprotor blade assemblies (28) each including a spar (40) and a sheath (52) extending spanwise along the spar forming the leading edge (48) of the proprotor blade assembly. The spar has a root section (42), a main section (44) and a tip section (46). The spar has a generally oval cross section at radial stations along the main section and a first edge having a structural bias relative to a generally oppositely disposed second edge at the radial stations along the main section.

摘要： There is a method of making a tubular specimen (314) with a predetermined wrinkle defect including providing (301) a layup tool (302) with a cavity forming member (302m) having a cavity (302c) which resembles a desired shape of the at least one wrinkle; orienting (303) a composite material around the mandrel at a wrap angle to form a closed loop; positioning (305) a wrinkle tool (306) on the closed loop; and/or generating at least one wrinkle with a predetermined characteristic in a portion of the closed loop to form a tubular specimen (314). The predetermined characteristic is at least one of the following: wrinkle location, an outward wrinkle, an inward wrinkle, a wrinkle width, a wrinkle height, and a wrinkle length. In another aspect, there is a method of offset load testing a tubular composite specimen (334). In a third aspect, there is a method (400) of determining allowable defects for a composite component.
