This is the strandard kind of fiberglass reinforcement which is used with polyester resin in hand lay up.
The
emulsion binder fiberglass chopped strand mat will be dissolved by resin within the resin and also
the fiberglass is totally wet out with resin when the laminate virtually
becomes clear. The resin demand is 2.25 : 1 , which means 1kg of
fiberglass mat desires 2.25kg of resin to wet it out.
