(Received January 28, 2002 ; revised manuscript received June 17, 2002). Surface treatment was carried out by an Excimer Pulse laser beam in order to increase the adhesive strength of vulcanized rubber. With increasing number of laser beam irradiations, the adhesive strength was greatly increased; the adhesive strength was 1,500 N/m after irradiation 100 times. The energy density increase was in direct proportion to the adhesive strength increase; the maximum value of the adhesive strength was 1,500 N/m at the energy density of 176 mJ/cm2. It was concluded that the increase of surface area was relevant to that of both energy density and adhesive strength Classification code : LO.050.. 335.
