INTRODUCTION
· It
is the method of production of fiber-reinforcement plastics.
· It
is the open mould process.
· It
is the simple and oldest method.
· There
is virtually no limit to the size of the part that can be made.
· The
mould can be made of wood, sheet metal, plaster and FRP composite.
· Working
· In
order to produce a composite by using glass fibres and polyester resin, a gel
coat is first applied to the open mould.
· Fibre
glass reinforcement which is normally in the form of a cloth or mat is manually
placed in the mould.
· After
pouring the plastic resin which are mixed with the catalysts and accelerators.
· Rollers
are used to remove entrapped air.
· To
increase the thickness of the composite being produced, more layers of fiber glass mat and resin are added.
