COMPOSITE FAILURE2Composite FailureComposites are crucial to the construction of an plane’s structure. They are a lightweight material typically made from carbon fibers and epoxy resins that is meant to be durable and strong. All aircraft undergo constant changes in pressure during routine flights and those changesin pressure can cause extreme stress to exterior and interior surfaces. In a particular incident involving a Naval tactical aircraft the composite lower wing skin revealed a defect after being inspected through an ultrasonic inspection. By the means of Non-Destructive Testing, metallurgy other composite professionals, the defect was able to identified. The defect occurred when the material disbanded between a splice plate and primer bond which eventually led to a delamination fatigue crack. Because of the
