VaRTM工艺是一种低成本的复合材料制造技术，与预浸料层压复合材料不同，树脂在真空压力下注入在模具上形成的干燥织物中，接近产品形状，并在烘箱中固化。这一过程已被用于制造风车等商业产品。本研究探讨了改进现有VaRTM技术的方法，使其能够应用于飞机主结构的制造，并改进VaRTM材料、工艺和成本。验证了VaRTM材料的力学性能与预浸料基本相当，在三菱喷气机尾翼上的应用前景是可行的。开发工作正在进行，目的是实现进一步降低成本，并符合未来将该工艺应用于民用商用飞机生产的法规。
The VaRTM process is a low cost composite fabrication technique, differing from prepreg laminated composites, the resin is infused into dry fabric formed on a mold near product shape under vacuum pressure and cured in an oven. This process has already been utilized in the manufacture of commercial products such as windmills. This study examined ways to improve existing VaRTM techniques so that they can be applied to the fabrication of aircraft primary structures, and to improve VaRTM materials, processes, and cost. It was verified that the mechanical properties of VaRTM materials are almost equivalent to those of prepreg materials, and that the prospects of applying them to the empennage of the Mitsubishi Jet are feasible. Development work is proceeding with the aim to realize further cost reductions and to obtain conformance to regulatory on the application of this process to the production of civil commercial aircraft in the future.
