Manufacturing Process For Reinforced Plastic Parts

Two processes that are open mould and close mould are commonly utilized for manufacture of reinforced parts. Hand layup procedure consists in applying a thin gel coat on the open surface of mould, laying fibreglass mat or cloth on the gel coated mould and brushing the matrix resin upon the fibres. The liquid resin may be sprayed or poured also. The

 accelerators and catalysts are further added to the resin before pouring. The brushed surface is rolled along with rollers for removing entrapped air and spreading resin consistently. The woven fibre or cloth is added like selective sites in the mould to raise thickness of the part as mentioned in design requirement. Boat hulls, panels and tanks are made via this procedure. Hand layup procedure is shown in following figure.
