A method of determining allowable defects for a composite component comprising: identifying at least one wrinkle characteristic of a composite component wrinkle defect; making a first plurality of specimens each having a predetermined wrinkle defect representative of the composite component wrinkle defect, the step of making a first plurality of specimens comprises making each of the first plurality of specimens by a method comprising: orienting a composite material around a layup tool at a wrap angle to form a closed loop, including a top arcuate portion, a bottom arcuate portion, and a hollow portion between the top arcuate portion and the bottom arcuate portion; generating at least one wrinkle with a predetermined characteristic in a portion of the closed loop by stretching it between the top and bottom arcuate portions with a stretcher, wherein 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; and curing the closed loop to form the specimen having the predetermined wrinkle defect; measuring each of the predetermined wrinkle defects in the first plurality of specimens for at least one performance metric to generate performance data; and generating an allowable wrinkle defect profile based on the performance data from the first plurality of specimens. identifying at least one wrinkle characteristic of a composite component wrinkle defect; making a first plurality of specimens each having a predetermined wrinkle defect representative of the composite component wrinkle defect, the step of making a first plurality of specimens comprises making each of the first plurality of specimens by a method comprising: orienting a composite material around a layup tool at a wrap angle to form a closed loop, including a top arcuate portion, a bottom arcuate portion, and a hollow portion between the top arcuate portion and the bottom arcuate portion; generating at least one wrinkle with a predetermined characteristic in a portion of the closed loop by stretching it between the top and bottom arcuate portions with a stretcher, wherein 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; and curing the closed loop to form the specimen having the predetermined wrinkle defect; orienting a composite material around a layup tool at a wrap angle to form a closed loop, including a top arcuate portion, a bottom arcuate portion, and a hollow portion between the top arcuate portion and the bottom arcuate portion; generating at least one wrinkle with a predetermined characteristic in a portion of the closed loop by stretching it between the top and bottom arcuate portions with a stretcher, wherein 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; and curing the closed loop to form the specimen having the predetermined wrinkle defect; measuring each of the predetermined wrinkle defects in the first plurality of specimens for at least one performance metric to generate performance data; and generating an allowable wrinkle defect profile based on the performance data from the first plurality of specimens. <EOS>
