Tape —A composite product form in which a large number of parallel filaments (such as tows) are held together with an organic matrix material (such as epoxy) commonly referred to as prepreg (preimpregnated with resin). The length of the tape in the direction of the fibers is much greater...

... to1000 ksi (2000 to 7000 MPa) and moduli of 30 to 145 msi (4 to 21 GPa). With this wide range of properties, carbon fiber is frequently classified as either (1) high strength, (2) intermediate modulus, or (3) high modulus. Both carbon and graphite fibers are produced as untwisted bundles called tows...

... provisions, such as casters with wheels and tow bars, are provided for movement. The fabrication approach for Invar-type tools is very similar to that for steel tools except that more cast shapes are used that are then welded to final contour. If the contour is simple, it may be possible to roll a metal...
