In the last years fibre reinforced plastic have increase their use in structural application due to their high specific strength. Although in many application composites are cured to final shape, cutting and drilling can still be required. However machining of CFRP composites with conventional cutting methods produce tool wear, damage such as delamination and fibre pull out [1-2]. Laser cutting is a possible alternative that not involve mechanical cutting forces or tool wear, and allow to obtain complex shape too. However, laser cutting is based on the thermal interaction between laser beam and the materials, that produce heat affected zone (HAZ).

Abstract
In the last years fibre reinforced plastic have increase their use in structural application due to their high specific strength. Although in many application composites are cured to final shape, cutting and drilling can still be required. However machining of CFRP composites with conventional cutting methods produce tool wear, damage such as delamination and fibre pull out [1-2]. Laser cutting is a possible alternative that not involve mechanical cutting forces or tool wear, and allow to obtain complex shape too. However, laser cutting is based on the thermal interaction between laser beam and the materials, that produce heat affected zone (HAZ).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
