| Abstract: | The cure kinetics of the resin VB-90 for vacuum-bag-only composite systems was investigated under dynamic curing conditions by differential scanning calorimetry(DSC) technique.The cure kinetic equation of the resin was established.Experimental validation shows the cure kinetic equation acquired agreed well with the experimental results,and it can be used for optimizing the processing cycle of the composite systems.The quality and properties of the vacuum-bag-only composite VB-90/T700 was studied: the void c... |
