Filament Wound Epoxy Tubing Is a Type Of Composite Tube

Feb 10

Filament wound epoxy tubing is a cylinder or pipe constructed from fiberglass reinforcements that have been impregnated by cured epoxy resin. It has the highest strength-to-weight ratio out of all types of composite tubing, and is available in sizes from small to large. It is a great choice for medical devices as well as electromagnetic radiation applications since it has a low coefficient thermal expansion.

Reinforcement Materials

There are many different materials that can be used to strengthen the filament wound epoxy tubing depending on the application. The most popular are carbon fibre fabric, and Kevlar. As reinforcements, graphene and various softer rubbery materials are also possible.

Resin System

Master Bond stocks a variety of epoxy resins to be used in the production of fiber-reinforced composite parts. These systems are engineered for excellent dimensional stability as well as high dielectric property as well as corrosion resistance and low CTE.

Low viscosity epoxy resins work best for this purpose, as they permit the infusion of and distribution of reinforcement into the epoxy matrix. They also have a longer lifespan which allows the production of the composite in greater quantities than pre-reg alternatives.

The most up-to-date filament winding software calculates fiber location and wind angle in accordance with to the design specifications. This includes either radial strength (short "hoop") or axial & longitudinal strength (short "helix") The result is a composite structure that exhibits a balance between axial & circumferential tensile strengths, with high hoop strength delivering the radial stiffness.

Nano-sized fillers can enhance the performance of a filament wound material by providing increased toughness, impact, and flexural properties. SWCNTs, for instance have been proven to improve flexural and impact resistance of glass fibre-based GFCCs reinforced with epoxy when employed in the range of 0.05 wt. % to 0.1 wt. percent of the total resin content in the final product.

This effect can be achieved using a combination mechanical stirring, calendaring and curing processes. This method of creating composite products has several advantages over prereg. It is easier to place reinforcement and does not require autoclaving.

This kind of fabricated item is used in a variety applications, including but not only bushings and filters, drive shafts and high voltage insulators, as well as printed wiring boards (PWB). They also have a good resistance to heat, solvents and chemicals, which is vital for composites and industrial tooling.

Our fiberglass filament wound tubes are made in diameters of 4 to 1000 millimeters and can be processed in accordance with the requirements of the user, such as turning, notch, wire or other electrical applications. They are of aesthetically pleasing external and internal surfaces that are free of special coatings or finishes and can be made in any shape or size to meet the needs of the final usage. They come in a variety colors. They can be cut using a fine hacksaw, band saw or dremel.
