**Abstract**
 PMMA is the most widely used denture base material because of its appearance and processability. However, it has unsatisfactory impact and fatigue strength. Reinforcement with carbon fibres was carried out to improve these properties, and surface treatment of the carbon fibre by Nd:YAG pulse laser irradiation was performed in order to improve interfacial bonding of the reinforcing fibre and polymer matrix. Laser light intensity was adjusted at 1—mJ per pulse in order to change the fibre surface roughness and avoid rupture of the fibre. The increased surface roughness improved the interfacial adhesion. This was verified by scanning electron microscopy and a tear-off method. It was also established that use of laser irradiation enhanced the wettability of the fibres by introducing active sites onto the fibre surfaces which react with the resin and lead to stronger interfacial adhesion. 14 refs.
