Because of their high properties, FRPs (Fiber Reinforced Plastics) have been at the center of attention. They consist of the high-strength and high-modulus fibers and the heat-resistant and corrosive-resistant plastics. In some cases, FRP is required to be machined to apply it to the electronic parts etc, especially very high performance drilling. Therefore in this research, hole drilling of FRP with YAG laser is treated as the objective and the workability is inquired into in detail. Irradiating time and flash lamp voltage are changed in wide range and the hole configuration and HAZ are observed. The appropriate conditions of YAG laser are proposed clearly.
