What is fiberglass used for and its characteristics?

Fiberglass, as its name implies, is a material consisting of numerous extremely fine glass fibers.

Fiberglass is commonly used as an insulating material. It is also used as a reinforcing agent for many polymeric products, to form a very strong and lightweight composite material called fiber reinforced plastic. glass (GRP). Fiberglass has properties comparable to other fibers such as polymer and carbon fibers. 

Material

The fiber can be made by a direct melt process or by a remelt process. Both start with raw materials in a solid state. The materials are mixed and melted in a furnace.

Technical Specifications:

Applications:

  • Industrial uses: used for products where high chemical resistance is needed, for cooling towers, roofing material, water tanks, bathtubs, pipes, ships.

COMMERCIAL FORMS OF FIBERGLASS

In the fiberglass-reinforced plastics industry, depending on the part to be obtained and the forming method used, there is a wide range of glass fiber shapes on the market that can be used.

roving

Roving is a strand of continuous strands of fiberglass filaments with a certain mechanical twist, made with Type E glass. It is used for pultrusion and filamentary winding. Twistless roving is generally used for the spray laminating process.

Chopped yarn (long staple)

Chopped strand is made up of continuous strands of Type E glass cut to specific lengths, which are designed for use in polyester and epoxy resin casting compounds.

milled fiber

Ground fiber is composed of glass filaments coated with a special size to make them compatible with specific resins and ground to provide a specific bulk density.

Fabrics

These fabrics are woven rovings, high performance fabrics, used to produce high strength fabrics for structurally sound applications such as shipping containers, ballistic armor, aircraft wings and doors.
