YAG laser drilling is a very efficient method to drill fine holes on multi-layer aramid fiber composites. Aramid short Fiber Reinforced Plastics (AsFRP) consists of the high-strength and high-modulus fibers and the heat-resistant and corrosive-resistant plastics. In some cases, AsFRP laminates is required to be machined in order to apply it to the electronic parts, especially Printed Circuit Board (PCB). Therefore in this study, hole drilling of FRP laminates with YAG laser is carried out and its machinability is investigated. Irradiating time and flash lamp voltage are changed in wide range and both a hole configuration and an extent of Heat Affected Zone (HAZ) are examined. The optimal machining conditions of YAG laser for drilling fine holes on multi-layer aramid fiber composites are proposed. Furthermore, temperature distribution in AsFRP laminates and thermal shear stress between the matrix layer and the sheet layer are analyzed by Finite Deferential Method (FDM).
