| Abstract: | Based on the characteristics of composite stiffened panels,We develop its process design of VARI integrated forming technology including the mold and the process steps,and then create some viable flow runner project to simulate and analysis by PAM-RTM.According to the results,we chosen the project with reasonable injection mode and flow run-ner to manufacture the stiffened panels by VARI process.the result of the nondestructive testing show that internal defect barely exists in the component,which proved that the process design and the simulation is effective. |
