Delamination analysis of carbon fibre reinforced laminates: evaluation of a spe...
António T. Marques; Luís M. Durão; António G. Magalhães; João Francisco Silva; João Manuel R. S. TavaresDrilling of carbon fibre/epoxy laminates is usually carried out using standard drills. However, it is necessary to adapt the processes and/or tooling as the risk of delamination, or other damages, is high. These problems can affect mechanical properties of produced parts, therefore, lower reliability. Production of higher quality holes is a challenge to everyone related with composites industry. In this paper, ...
Damage assessment of Drilled Hybrid Composite Laminates
Luís M. Durão; António G. Magalhães; António T. Marques; João Manuel R. S. TavaresHole drilling operations are common in fibre reinforced plastics - FRP’s - to facilitate fastener assembly to other parts in more complex structures. As these materials are non-homogeneous, drilling causes some damages, like delamination, for example. Delamination can be reduced by a careful selection of drilling parameters, drill material and drill bit geometry. In this work two types of laminates are dr...
Delamination Analysis of Carbon Fibre Reinforced Laminates
António T. Marques; Luís M. Durão; António G. Magalhães; João M. TavaresDrilling of carbon/epoxy laminates is normally carried out using standard drills, like twist or Brad drills. However, it is necessary to bear in mind the need to adapt the processes and/or tooling as the risk of delamination, or other damages, is high. These problems can affect the mechanical properties of the produced parts, hence, lower reliability. Production of higher quality holes, with damage minimization...
