Abstract: Due to its characteristics of mechanical anisotropy, poor thermal conductivity ability, drilling defects such as delaminations, tear and other defects are produced during the drilling process of fiber reinforced composites. This paper reviews the effects such as drilling thrust, drilling parameters and tool geometry on drilling defects of fiber reinforced composites. Furthermore, the current status of drilling technology is analyzed. Finally, reasonable technology parameters, tool geometry and new drilling technology which are important to improve the quality of drilling technology is proposed.

Key words: fiber reinforced composites, drilling defects, drilling technology
