.... Parts with long, thin sections or projections (webs and ribs) are more difficult to forge because they have more surface area per unit volume. The shape of the final forging determines process variables including friction, temperature changes in dies, and pressure required to fill the die cavities. The...

... tool during cure, resulting in gross porosity, especially in the relatively thin webs. Three actions were taken to resolve the porosity problem—(1) the cure was switched to an IPB-type cure to reduce the resin loss and keep hydrostatic pressure on the resin; (2) the solvent-impregnated woven cloth was...
