Sized as an A3 paper size at 300 x 420mm (12" x 16.5") this 1mm (0.040") pure carbon fibre sheet is still thin enough to be bonded to a surface to produce that 'carbon fiber look' this moderately stiff material is better suited to lighter loaded structural applications - Fantastic as a free standing dash board panel or auxilliary gauge/clock panel on a track/sports/kit car or indeed in highly loaded applications in modelling or robotics. It is important to note that it is only just in any way flexible and cannot be cut with sheers - you'll need a hacksaw or as we use - a jigsaw with a 'ceramic use' blade. If you can bend it into a radius you can actually measure, you are a LOT stronger than us!! This material is airtight and water proof.
