Removing trapped air in a laminate with a roller is a time-spending and expensive process…
Today, RTM, vacuum infusion, and other compression process have especially enabled composites professionals to save the long time spent in rolling laminates, but hand lay-up or spray-up in open moulds still remain the most widely used methods in the world.
And the chasing of air-bubbles with rollers is still omnipresent.
Euromere drives developments forward with FSP-NR No Roll process for the spray-up construction of composites parts.
FSP-NR process consists in spraying simultaneously polyester resin and fiberglass to build a laminate in which air micro bubbles will disappear by themselves.
Euromere has worked on the process and developed a FSP-NR material, which enables to build a sprayed lightweight laminate, with no need to roll on flat parts, and only light roll in complicate shape areas.
As backup of vacuum formed acrylic or behind gelcoat, the FSP-NR system permits to spray quickly thickness of several mm without having to use a roller, or only in sharp angles where the laminate cannot easily fit.
Product is sprayed with a standard equipment, with a few simple and low-price modifications (nozzle, filters, mixer).
