Fiberglass is a common form of insulation product that started out as one specific brand of insulation and has since become a generic term that is used to describe a material that has been constructed from small fibers of glass. These fibers are woven together in order to create reinforcement or prevent heat from passing through. This form of reinforcement is typically used within a plastic material and the glass fibers are arranged in a certain way depending on your application and the different requirements you may have of the fiberglass product. Fiberglass itself can be found in a vast number of industries and applications such as boats, bath tubs, automobiles, swimming pools, water tanks, roofing, pipes, casts, and many other uses.
Fiberglass has a number of different properties that allow it to excel in this wide range of applications, it has rating for both compression and tension, it is weather resistant, comes with a variety of surface texture options, and is naturally resistant to a number of different corrosive elements. Fiberglass is manufactured through a process called pultrusion, which is a form of extrusion. However it differs from extrusion in that the process pulls the material as opposed to traditional extrusion methods where the material is pushed through the process. This process pulls the different materials needed to make the fiberglass either thermoplastic or thermosetting plastic in addition to the glass fibers and takes them through a series of processes. These processes include passing through a tension roller, soaking in resin, passing through a heat source, one final pass through the pulling mechanism to completion. As stated before, fiberglass can be used in wide range of applications so the manufacturing process may differ depending on the manufacturer's preferred methods and any specific requirements you may have.
There are a number of different types of fiberglass, common types range from polyester resin which is not reinforced and has a low tensile and compression strength of 55 megapascals (MPa) and 140 MPa respectively. To S-Glass Epoxy composite which has a tensile strength of 2,358 MPa and a compression strength higher than 350 MPa. In order to determine which type of fiberglass is best for your specific application, consult with an experience fiberglass manufacturer today.
