Notes:
For a present study, the surfaces of graphite/epoxy prepregs were modified using plasmatreatment to improve the delamination resistance behavior of graphite/epoxy laminated composites.The optimal treatment time was determined by measuring the change of contact angle with treatmenttime. Unidirectional DCB (double cantilever beam) specimens were used in the mode I delaminationfracture tests. The delamination resistance curve of regular (untreated) specimen was compared withthat of plasma-treated specimen in order to determine the effect of prepreg treatment on the resistancebehavior. It was found that contact angle was changed from ~64° to ~47° depending on the treatmenttime. The contact angle was a minimum for a 30 min treatment time. It was also found thatdelamination resistance behavior of graphite/epoxy composites was improved about 20%
