The close-up pictures to the right shows a cut with our ultrasonic cutter on the top and a cut with a laser cutter below. This materail is a very thick spectra cloth reinforced by carbon fibres. The laser cuted edge is thick and melted and the free ends of the carbon fibre create fringes outside the cut.

Our ultrasonic cutter has created an edge much smoother, but yet sealed by the very local heating effect of the ultrasound. Demanding cuts diagonally against the fibres are also easily done with Q-Bonds cutting device.
