Abstract

Fibre-reinforced polymer is a composite material made of a polymer matrix reinforced with Fibres. Factor which are mostly affecting resin bonding are Gel time and peak exothermic temperature which are different for different compounds. Since in Fibre reinforced glass plastic moulding all the raw material such as Fibre glass mat, resin, gel coat, catalyst, accelerator and pigment which are required for the production are constant. Since resin is the binder in Fibre reinforced glass plastic, resin can be considered as the key of the Fibre reinforced glass plastic moulding process. The factors on which resin depends are curing time, gel time, peak exothermic temperature and pot life. The main factors are curing time, gel time and peak exothermic temperature. Curing time, gel time, and peak exothermic temperature are different for different compound. Hence the only parameters that can be changed is catalyst and accelerator. Using different catalyst and accelerator may help in proper binding resin and hence it may result in a smaller number of unwanted defects which will ultimately lead to decrease the cost. Hence certain experiments have to be perform for getting the idea of effect of different catalyst, accelerator on resin.

Keywords

Accelerator, Catalyst, Gel time, Peak exothermic temperature, Resin.
