    摘要: A panel having a finish face, a substrate and a lamina of moulded polyurethane between the two is formed in a single closable die having two portions, the first stage of the operation being to spray a release agent onto a face forming surface of one die portion, then spray an aliphatic polyurethane colored film onto the release agent, spray an elastomer polyurethane over that film and allow the elastomer to at least partially set, lay a sheet of reinforcing fibre which can for example be a continuous filament glass over the at least partially set elastomer, dispense the liquid ingredients of a rigid foam polyurethane over the glass, close to the mould, and remove the product after setting.

    摘要: A rotor yoke manufactured by a process comprising preparing a molded rotor yoke in a closed cavity tool and possibly machining at least one portion of the molded rotor yoke to form the rotor yoke. In the preferred embodiment, the preparing of the molded rotor yoke is accomplished by applying layers of uncured low-flow composite material and a layer of uncured high-flow adhesive; substantially enclosing the uncured molded rotor yoke in the closed cavity tool; and applying pressure so as to compress the uncured molded rotor yoke; and curing the uncured molded rotor yoke. During the curing process, the high-flow adhesive bleeds out of the molded rotor yoke, thereby preventing marcels from forming through movement of the low-flow composite material.
