摘要：

Previous research has shown that sprayable tackifiers containing preformed rubber particles can be successfully integrated in the manufacturing process of vacuum assisted resin transfer molding (VARTM) composites. This research showed that large increases in interlaminar fracture toughness of the fiber reinforced composites was possible with no significant reductions in interlaminar shear strength or thermal properties. In the present study, different amounts of tackifier were sprayed onto woven carbon fabric and the effects of the tackifier concentration were investigated in terms of changes in processing, mechanical performance, and thickness. Interlaminar fracture toughness increased with increasing tackifier concentration, however, the interlaminar shear strength of the materials decreased and the laminate thickness increased with increasing tackifier loading.
