Experimental study of drilling carbon and aramide fibre reinforced composite material

Parts made out of composite materials are joined and connected by elements for joining into complex construction sections and subsections. For this purpose, it is necessary to fabricate numerous holes with different dimensions. Drilling is one of the most important cutting operations which are currently carried out on fiber reinforced composite materials. The following errors are presented during the drilling of composite materials: delamination, fuzzing, edge chipping, spalling, surface roughness, roundness and dimensional errors. With correct choice of cutting regimes and cutting tool geometry it is possible to ensure required quality of the drilled holes. This paper gives research results of drilling carbon and aramide fibre reinforced composite materials.
