To investigate the curing process of composite material, the bidirectional couple model including
thermal transfer and curing dynamics for polymer composite material curing process is established. According to the
existing curing criterion, the cylinder composites structure is analyzed in this paper, and the temperature and degree
of cure distribution at internal and outside face sheet is worked out. With the calculation results, because of the
mould’s thermal conductive ability is low, the temperature at the face sheet next to the mould ascends slower than the
face sheet at the other side. However the temperature distribution is more uniform.
