..., which cuts glass roving into 25.4 mm (1 in.) lengths. After the glass falls to the resin bed, another carrier film with another layer of paste is added on top, sandwiching the glass between the two layers. When the paste is first mixed and put in the SMC machine, it has the consistency of pancake...

... is the spray-up process. Glass rovings are chopped and sprayed on a rotating screen. A small amount of resin is introduced into the stream of chopped glass, and when the glass accumulates on the screen to the proper weight, the resin is heat-cured, causing the preform to retain its shape. The vacuum applied...
