Curing is a term in polymer chemistry and process engineering that refers to the toughening or hardening of a polymer material by cross-linking of polymer chains, brought about by electron beams, heat or chemical additives.esin curing [edit]. Despite the wide variety of thermoset resin formulations (epoxy, vinylester, polyester, etc.), their cure behavior is qualitatively identical.
The brake drum mounts on the axle or wheel hub, and some drums incorporate the hub. Most brake drums are made of solid cast iron, but there are also steel and aluminum drums with cast iron liners. The machined friction surface on all drums is cast iron.
Two types of brake assemblies are in use, drum brakes and disc brakes. Drum. brakes generate braking force on the inner surface of brake drum, the force applied is. radially outward to contact the drum. The wheel-wheel studs are attached to the drum, thus when the drum stops the wheel also stops.
