Manufactured here at our works by laminating and compressing two layers of 200g woven carbon fiber (fibre) fabric under a vacuum and curing the product at 120 Deg C, which produces a 0.4mm (0.016") thickness (16 thousandths of an inch)
Although considerably stiffer than the single layer 0.2mm sheet - so a lot better for constructing box shapes and air ducts for example, this is still a very light material with an amazing surface finish. It can be bonded to a surface using adhesives to produce carbon veneers and is slightly more 'workable' as it has a bit more rigidity. Still light enough for very light applications (model aircraft for example) - indeed excellent for bulkheads and stiffeners as well as more self supporting wing or fuselage skin applications. This is the stuff we supply to make door cards for full sized race car applications and internal panelling. It is important to note that it is still a flexible material and is easy to cut with a pair of sharp shears. When we say flexible, we mean you can bend it around single curvature surfaces by hand and get a radius down to less than 50mm (2 inches) very easily - but not much less - but as with all carbon fibre sheet, it will not 'plastically deform' - ie when bent, it will not stay there unless you hold it with adhesive to a former. This material is airtight and water proof.
