Method for producing fiber-reinforced composite member with connecting holes, and structural member for aircrafts constituted by such composite members

摘要

A method for producing a fiber-reinforced composite member with connecting holes, comprising boring a cured molding of prepregs of reinforcing fibers impregnated with a matrix resin to form the connecting holes, using a burnishing drill comprising two or more tapered tip blades, two or more circumferential blades extending continuously from the tip blades to a shank, and chip-discharging grooves extending from the tip blades to the shank.
