The characteristics of carbon fibre reinforced plastics had widespread their use. In order to join different components, drilling is often necessary. It is known that a drilling process that reduces the drill thrust force can decrease the risk of delamination. In this work, three combinations of the drilling process are compared: tool diameter and geometry and feed rate. The parameters considered for analysis i...
O crescente conhecimento das suas propriedades e o avanço nas técnicas do seu processamento têm permitido uma utilização cada vez mais variada dos materiais compósitos de matriz polimérica. Embora as aplicações mais frequentes estejam relacionadas com o uso de fibras de vidro ou de carbono como material de reforço, a utilização de fibras de reforço naturais tem vindo a merecer maior atenção. A utilização deste ...
For the past decades fibre reinforced plastics are increasing their importance as one of the most interesting group of material because of their low weight, high strength and stiffness. Good hole drilling processes are essential. To obtain good quality holes it is important to identify the type of material, ply stacking sequence and fibre orientation. In this paper drilling of quasi-isotropic hybrid carbon+glas...
