Simulation and Mould Design of Composite Transmission Shaft for RTM Processing

To improve the property of tail transmission shaft for helicopter,the RTM technological manufacturing scheme was proposed for the transmission shaft and a mould was developed.According to the design requirement of the transmission shaft,the shaft was designed,and the RTM filling process was simulated in the RTM simulation soft.As a result,the optimal filling pressure,the reasonable injection and outlet location were ensured.Then,the mould of the transmission shaft was designed on the basis of the simulating result,and the structure and the design process of the mould were researched.Finally,the mould manufacture and filling experiment were operated.The experiment results coincide with the simulation results.The property testing experiment on the transmission shaft shows that the property of the shaft can meet the design require.
