... Abstract Knowledge of fatigue behavior at the laminate level is essential for understanding the fatigue life of a laminated composite structure. This article describes fatigue failure of composite laminates in terms of layer cracking, delamination, and fiber break and interface debonding...

Fig. 4 Fiber arrangements. Composite laminates are generally fabricated by rotating lamina axes as shown by the twist example on the left. However, loads that are off-fiber axes cause large inter- and intralaminar matrix stresses. Safer structures can often be designed by using curved More

Fig. 1 Selection of lay-up pattern for fiber-reinforced composite laminates. All fibers in 0°, +45°, 90°, or–45° direction. Note: lightly loaded minimum gage structures tend to encompass a greater range of fiber patterns than indicated, because of the unavailability of thinner plies. More
