摘要：

The paper presents a new mechanical modeling of thermal mismatch residual stresses in composites. Some equations which can be easy used in order to calculate the three-dimensional state of residual stresses in fibers and matrix, in a unidirectional composite lamina, are carried out or adopted on the basis of a composite cylinder model, developed in Theory of Elasticity. Using these equations, residual stresses developed due to differential thermal shrinkage as it cools down from the high processing temperature to the ambient temperature can be predicted.
