Analysis od delamination in drilling of composite materials

Popis výsledku v původním jazyce

The aim of this work is to clarify the interaction mechanisms between the drilling tool and material. Among the defects caused by drilling, delamination appears as to be of the most critical and may occurs at both the entrance and exit plane. This paperpresents a prediction Hocheng-Dharan model of thrust force for drilling without delamination. HSS twist drills with different geometry were used for drilling of carbon/epoxy composites. Experiments were performed to validate physical model of delamination and investigate the effect of tool geometry and drilling paramenters on delamination. The results showed that proposed delamination model is adequate and that damage around drilling hole can be reduced significantly by proper selection of drilling conditions.
