Advanced polymer composites are widely used in high speed transport airframe structures and aircraft engine components due to their high strength, high stiffness, high temperature tolerance and light weight properties. One critical issue for structural designers and material developers is long term behavior of advanced polymer matrix composites (PMC) and their associated damage and failure mechanisms. For example, fatigue damage of a carbon/epoxy composite proposed for high temperature applications needs to be understood to predict its long term behavior. Experiments show that the first stage of fatigue damage of cross-ply laminates is transverse matrix cracking. This study focuses on fatigue matrix cracking in transverse layers and cracking multiplication prediction under fatigue loading. Fatigue damages at both room and elevated temperatures are characterized experimentally. Furthermore, Fatigue Monte Carlo technique is applied to simulate the nondeterministic transverse cracking procedure based on stress analysis model, stress-life curve and damage accumulation model. It is shown that the simulation based on Miner's rule agrees well with experimental results at both room and high temperatures.
