Abstract

A method of laser machining of a fiber-reinforced composite material of the present invention is characterized in that the fiber-reinforced composite material or composite ply material (ply material consisting of plates of metal or inorganic material and fiber-reinforced material) is cut using an ultra short pulse solid-state laser having a pulse-width ranging from 10 pico to 100 nano second and a pulse energy of 1mJ-500J, repeatedly irradiated to the material with the number of frequency ranging from 10Hz to 100kHz. According to the present invention, it is possible to work, e.g., cut, pierce, groove, or carve a fiber-reinforced composite material including CFRP, by removing materials by means of a laser with a high precision and good quality. It is also possible to form a fitting joint of proper shape so that a male-female joint may be available in a butt welding that has been hardly feasible. It is further possible to produce structural members such as a light weight panel or an H-column because the male-female joint can be used for a plate of any desired dimension (width, length and thickness).
