The use of natural fibres, such as flax, sisal or kenaf to reinforce plastic body panels for automotive applications is being introduced for car interior trim parts such as door panels, hat shelves, roofing, etc. The benefits derived from using natural fibres instead of glass fibres are mainly ecological and economical. As a renewable product, natural fibres have a greater environmental interest than oil based plastics. Natural fibres can be recycled and reused in a better way than glass fibres. On the other hand, panels made of natural fibres have good mechanical properties but being lighter than glass fibre reinforced panels, which mean lower fuel consumption and so cost savings. The aim of this work is to explore the capabilities of lasers to effectively cut these new type of natural fibres reinforced panels. A comparison between the abrasive water jet cutting and the use of a CO2 and Nd:YAG lasers has been carried out. The quality of the cuts obtained by using a sealed CO2 laser is much better than that obtained by using an abrasive water jet machine. The economical and environmental aspects involved in the cutting process are also favourable to the sealed CO2 laser.
