Carbon Fiber materials have many uses and applications.  Musical instruments can be made with carbon fiber materials as the video below demonstrates.  The Cello is made by hand cutting and laying the materials in the mold prior to the application of heat and pressure.  The pressure is applied via vacuum bagging.  The cello is multi-piece construction that is bonded together.  The assembly is then sanded and clear coated with polyurethane.
