摘要： A particular composite test specimen includes a first tab, a second tab, and a gage section between the first tab and the second tab. The first tab, the second tab, and the gage section are machined from a composite test blank. The composite test blank includes a plurality of plies arranged with first ply layers having fibers oriented in a first direction and second ply layers having fibers oriented in a second direction, where the first direction is different than the second direction.

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.

摘要： A coating bond test method includes, attaching with an adhesive a pull-off bar to a coating on a planar surface of a substrate for which a normal bond strength between the coating and the substrate is sought, reducing a first area defined by an interface between the substrate and the coating to a value less than a second area defined by an interface between the adhesive and the coating, urging the pull-off bar away from the substrate in a direction normal to the planar surface until failure occurs, and recording a load at which failure occurred.

摘要： A method for use in determining hydrogen embrittlement in a plated sample is provided. The method includes positioning the plated sample between a first holding member and a second holding member, moving the second holding member towards the first holding member to bend the plated sample, and applying a static load to the plated sample for a predetermined duration of time. The static load is applied by bending the plated sample to a distance between the first and second holding members that is a predetermined percentage of a baseline ultimate failure distance of the plated sample.
