The influence of vaper-grown carbon fibers (VGCFs) as a filler on the isothermal cure reaction of tetraglycidyl-4
4'-diaminodiphenylmethane (TGDDM)/4
4’-diaminodiphenylsulphone (DDS) epoxy was studied using differential scanning calorimetry (DSC).When VGCFs were incorporated into the TGDDM/DDS system
the activation energy of the composites decreased The cure reactions of VGCF composites showed an autocatalytic behavior as well as the pure TGDDM
DDS epoxy.DSC experimental results showed that VGCF had very small effect on cure kinetics of the TGDDM/DDS system A modified autocatalytie model was used to describe the cure reaction.Good agreement between data of the nlodified autocatalytic model and the experimental ones was found over the whole curing temperature range for both neat TGDDM/DDS epoxy and its VGCF composites.
