摘要: |
A low-cost Vacuum Assisted Resin Transfer Molding (VARTM) process has been developed to manufacture Fiber Reinforced Polymer (FRP) composites. In VARTM, a fiber preform is placed into a one-sided mold and the mold is vacuum sealed. Resin is then drawn into the mold by vacuum to infuse the preform. Resin flow is assisted by microgrooves built into a distribution medium placed beneath the vacuum bag. After full infiltration of the resin has been achieved, the mold is heated to the curing temperature and the part is solidified. The process has certain advantages such as low cost one sided hard tooling, net shape manufacturing of large complex parts, and high fiber volume fraction. Physics based process simulation tools is be used for the optimization of the injection locations and resin infusion during the process. This process can be used to manufacture complex shapes and multifunctional composites. A multifunctional structure is a unique design approach with the composition of structures performing several functions beyond carrying mechanical loads. It involves integration of several functions such as flame resistance and impact resistance. Physical and mechanical tests are performed to evaluate the performance of the manufactured parts. |
