以玻璃纤维为增强材料，环氧树脂为基体，采用一种对真空辅助树脂传递模塑(VARTM)工艺的改进型成型工艺——真空室辅助VARTM(VIPR)工艺制备了环氧树脂／玻纤复合材料。VIPR工艺是在VARTM工艺的基础上附加了一个真空室，以增大纤维预成型体的渗透率。结果发现，存在附加真空室的情况下，树脂在纤维间的渗透率更高，最终得到的复合材料的力学性能更加优异。并且发现，附加真空室压强为50 kPa时，渗透率达到最大值，附加真空室的压强为30 kPa时综合力学能最佳。

Epoxy/GF composites was prepared with glass fiber as reinforcing material,epoxy resin as matrix by using a vacuum assisted liquid molding (VARTM) improved molding process—vacuum induced preform relaxation(VIPR) technology. VIPR technology is based on VARTM technology added to a vacuum chamber to increase the permeability of fiber preform.The results show that the additional vacuum chamber causes the compressive forces compacting the fabric to decrease allowing the resin to flow faster in the effected region under the chamber,the mechanical properties of composites are more excellent.What is more, when the vacuum pressure is 50 kPa,permeability is the largest and when the vacuum pressure is 30 kPa,comprehensive mechanical properties are the most excellent.
