Test specimens were of two types, tubes and domed-end cylindrical pressure vessels, with filament wound [±a,90] helical/hoop construction. Fiber/epoxy laminates using AS4 graphite fiber, Kevlar 49 fiber, and intraply hybrids combining these fibers were tested. The tubular specimens were subjected to internal pressure with superimposed axial load to determine in-plane mechanical properties. The vessels were tested under internal pressure to correlate the tube data and then burst tested to establish ultimate material strengths. Room temperature creep and recovery tests were included to demonstrate timedependent behavior.Read More
