... trade names, the most common being Mylar by DuPont.) The boPET sheets can then be used to support the preimpregnated ply as it is moved to the lay-up. Some manufacturers improve the quality and productivity by building their own impregnation machines. One simple example is shown in Fig. 5.2 , in which...

... . The number of circuits must, by necessity, be a whole number, so if the value is rounded up, there will be some overlap of the band edges, and if the value is rounded down, there will be gaps between each of the bands. Winding with overlaps will give some increased unevenness of the outer surface...

..., and their overall good combination of physical and mechanical properties. Spray-up is a low- to medium-volume, open-mold method similar to hand lay-up in its suitability for simple medium to large part sizes. However, greater shape complexity is possible with spray-up than with hand lay-up. Continuous-strand...

... and welded in a plate. When making our part, we machined through the weld and into the separation of the casting and the plate. The interesting conclusion to the story is that we ended up using the part. Because we needed the part so badly, we welded it again to produce a band-aid fix of our own...

... in this task. ASTM recommends the sample surface roughness, R a , should be greater than 0.4 μm to reduce the chances of the paper sliding over the sample. Up to 1.6 μm may be necessary to avoid sliding. Other standards suggest that a R a of 3.2 μm may be a safer value for this purpose ( Ref 9...
