Hand Lay –Up of Composite Component
In this process the mould to be used for hand lay-up
is coated with releasing agent followed by layering of the reinforcement
fabric. The resin is then poured onto each layer and spread evenly coating the
fabric using laminating equipment such as a roller or sponge. The prepreg is
laid in position eliminating all air pockets and repeated until the hand formed
desired shape is obtained. It is then cured under heat, vacuum or pressure.
(prepreg -A reinforced-plastics term for the reinforcing material that contains
or is combined with the full complement of resin before the molding operation.
Spray –Up Process – Mechanical Spray System
In this process a mechanical spray system consisting
of an air-pressurized mixture pot, of resin and a metered catalyst supply, and
a chopper gun, connected to both the reinforcement supply, in the form of glass
strands, or other reinforcement material, and the resin mixture, in the pot and
catalyst supply.
