The results of using optical fibre delivered laser power to remove the surface of a range of representative and large scale concrete samples will be described. (W 83) (1)

Optical fibre = Fibra ótica

TWI has recently invented a new method for improving the control of induction welding thermoplastic composites without additional susceptors. Inserting a thin electrically-insulating layer (gauze) between adjacent layers containing nonaligned carbon fibres prevents electrical pathways from being formed and volumetric heating is disabled. (W 20) (2)

Carbon fibre = Fibra de carbono

The laser beam excitation and manipulation, allows for a very compact laser source, which can also be delivered to the work-piece by a separate delivery fibre giving it much of the flexibility of the Nd:YAG lasers. (W 222) (3)

Delivery fibre = Fibra de entrega
