What is the Fibre Glass Coating ? Fibre Moulding ?
Fibre Coating Generally, in Fibre sheet,cement sheet,Metal sheet, pipe, tank and chemical plant component manufacture it is essential to protect the structural laminate from the environment to be contained. Often this can be achieved with a fibre reinforced barrier coat 2 to 3mm thick manufactured using surface tissue, light weight fibre mats and cloths using a suitable chemically resistant resin. In such cases gelcoats are not used because a pure resin without additives provides a greater level of chemical resistance. Hence, the resin-rich surface tissue provides the initial chemical resistant surface and will contain around 95% resin by weight, which is further supported by a resin-rich, structural laminate barrier layer before the final GRP structure is manufactured. FRP Coatings Protect the fibre Moulding Structures.
In this Section the need and performance of specialized protection systems for composite materials will be discussed with reference to the various market requirements.
Fiber Coating is just what the name sounds like…very tiny fibers of glass. Glass is one of the world’s oldest and most available materials. Fiber Coating was first created by accident in 1932 by a young Owens-Illinois researcher named Dale Kleist. He was working to attempt to weld together architectural glass blocks to form a vacuum-tight seal. A jet of compressed air accidentally struck a stream of molten glass he was working with resulting in fine glass fibers. Mr. Kleist then refined the process to utilize steam instead of air. Steam is cheaper, he reasoned, and would produce a finer fiber. Kleist was correct. The result was a glass fiber material thin enough to be used as a commercial insulation.
how to repair fiberglass OR Fibre Moulding
- Drill a tiny hole at each end of the crack. This will stop the crack from extending any further.
- Examine the crack. If it’s a hairline crack, use an electric or hand held rotary blade to widen the crack just a bit. This will make it possible to fill the crack with epoxy resin.
- Wipe the crack with a dry rag to make sure it’s clean and dry. If it’s not clean and dry the epoxy won’t adhere well.
- Fill the crack with a fair amount of fiberglass epoxy resin, using a plastic applicator. Make sure the crack is completely filled.
- Let the epoxy dry for a day. When the area is dry, smooth the surface with sandpaper.
