Uses for Filament wound epoxy tubing commonly called g10, made of glass fabric that has been bonded to an epoxy resin. It is widely used in the automotive and aerospace industries, as well as medical equipment and composite pressure vessels for use in harsh environments.
They are made by a process called filament winding where continuous glass fibers are bent to form a tube and connected to an epoxy resin. The process produces high strength and lightweight composites that are able to withstand extreme temperatures and resist corrosion making them a good choice for a range of applications.
Options to strengthen
Medium- and low-weight fiberglass reinforcements are most well-known, but there are many materials that can be used in composite strengthening. These include carbon fiber, glass fiber and Kevlar (a manufactured plastic) as well as hard nano-fillers, such as graphene, and soft rubbery materials.
Selecting the right fiber for your application is key to get the most value of your laminate. It can affect the way it bonds with epoxy resin as well as how it performs once it is in service.
You must consider the final conditions of your service and budget before you choose a material for your project. This will allow you to determine the best fabric for your needs, if you need it to be strong or flexible, and the type of epoxy resin you’ll be working with.
Many factors can impact the performance and longevity of a laminate made of fiberglass, for instance, how long it takes to cure. You can also select how much surface tack is required.
General purpose laminating resin is one type of polyester resin that’s well-known for its wide range of general fiberglass applications. It is a good adhesive and is cured by an adhesive tack.
The thickness of the resin may affect its performance as well, with thicker formulas offering greater mechanical strength and durability. There are a variety of viscosity options available, including high-viscosity and low-viscosity resins.
These formulas are thicker than lower viscosity formulations and have a paste-like consistency. Technicians employ these formulas for projects that require extreme durability and strength, such as filament winding and vacuum bagging.
High-viscosity epoxy formulations are thicker than low-viscosity ones and are able to withstand moderately hot temperatures. These formulas are often employed for filament winding and vacuum bagging and tooling.
There are also specialty fiberglass resins, like high viscosity polyurethane systems which delivers high stiffness. This formula is great for use in pultrusion processes in which it can be used as a basis to make springs that are able to carry larger loads.
There are three kinds of epoxy bonds: by proximity by ionic, by proximity and through chemical reaction between the the bonding surface. These bonds can be strengthened by using different reinforcements, or by adding additional additives to the epoxy to boost its performance.
