Nowadays, fibre reinforced plastics are used in a wide variety of applications. Apart from the most known reinforcement fibres, like glass or carbon, natural fibres can be seen as an economical alternative. However, some mistrust is yet limiting the use of such materials, being one of the main reasons the inconsistency normally found in their mechanical properties. It should be noticed that these materials are ...
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 ...
The use of fiber reinforced plastics has increased in the last decades due to their unique properties. Advantages of their use are related with low weight, high strength and stiffness. Drilling of composite plates can be carried out in conventional machinery with some adaptations. However, the presence of typical defects like delamination can affect mechanical properties of produced parts. In this paper delamin...
