Research of heated winding process for composite based on “birth and death” method

The process of heated winding process for composite in which winding and curing occur at the same time and influence mutually is complicated. The fields of inside the composite have effect on each other while the layers wound are influenced by curing reaction. In this paper, the two dimensional model is built layer by layer in ANSYS and the model is activated using elements “birth and death” method to simulate the heated winding process. We can know the distribution of temperature and curing during winding by the charts of temperature field and curing field. The centre nodes of first, fifth and tenth layer are observed to obtain curve of temperature and degree of cure, from which the change of temperature and curing in the layer above during winding is obtained.
