摘要：

The effect of the surface cooling on the fatigue life of a glass/epoxy laminate during fully reversed bending tests is investigated both experimentally and analytically. The experimental tests involve the use of acoustic emission and infrared thermography to monitor the structural integrity and evolution of damage. An analytical study is also performed to calculate the stress in the outermost layer of the laminate for both cases of cooled and uncooled specimens. The results show that the life of the laminate is highly dependent on the temperature and that surface cooling, if done appropriately, can significantly increase the fatigue life of the laminate.
