FRP Manhole Cover:

It is a composite material of Thermoset resin mainly polyester resin, with a matrix of glass fibers reinforced in it & quartz as an aggregate. Reinforcing glass fibers of varied types & categories are arranged in a fashion to suit specific load capacities & polymer resin is applied to it which acts as the binder to the composite material. Aggregates of Quartz mixed with resin are then added & the mixture of the above creates a composite material that is very high in compressive, tensile & flexural strength.
