Stress Development in the Process for a Hybrid Fiber Wrapping Cylinder
In a curing process, there is an intensive residual stress in a cylinder with a reinforced part wrapped by hybrid composite due to the kinds of fibers and mismatch material properties. The development of residual stress in the cylinder is investigated by a finite element model combing with the classical laminate theory and heat conduction. The level of residual stress at the ends of reinforced part is higher than else location, a cure cycle with a lower cure temperature would reduce the residual stress. An improved cure cycle is proposed by comparing the simulational results of the cylinder cured with different cure cycle.
