Epoxies for Filament Winding

Master Bond offers a broad range of epoxy resin systems for the fabrication of filament wound composite parts. Oven/autoclave curing epoxy coated/impregnated reinforced fibers including glass, carbon, aramid, boron are uniformly, precisely wrapped around a cylindrical, spherical, conical rotating mandrel automatically to produce composite structures. Thin walled, light weight, high strength composite tubes, pressure vessels, tanks, cylinders, pipes exhibit superior dimensional stability, dielectric properties and corrosion resistance. They are employed for filter housings, bushings, drive shafts, high voltage insulators, rolls, wastewater treatment components and pipelines.

Formulating epoxies with special properties

Available in a variety of viscosities, Master Bond toughened, resilient, 100% solid two component epoxy systems for filament winding have convenient mix ratios, good wetting characteristics and cure rapidly at moderate temperatures. . In order to achieve consistent, repeatable results proper processing techniques should be strictly followed. Winding angle/tension, following proper cure schedules are essential to assure optimum performance. Special systems are engineered to reduce dripping, waste, lower labor costs. Custom products offer outstanding tensile, impact, compressive, flexural strength and protect against weather, fire, wear. Select grades have high glass transition temperatures, low thermal coefficients of expansion and withstand thermal shock. Specialty cryogenically serviceable, low outgassing grade epoxies are also available for aerospace applications.

Filament Winding Hollow Tube Structures

Epoxy resin impregnated rovings or monofilaments such as carbon, e-glass, s-glass, aramid are wound around a mandrel to fabricate standard/custom composite hollow tube structures. Master Bond oven curing epoxy resin systems offer consistency, repeatability, cost effectiveness for usage in hoop, helical, polar winding patterns. They accommodate high fiber to resins ratio and allow precise fiber orientation at different rotational mandrel speeds. Filament wound epoxy matrix tubing in a variety of diameters/wall thicknesses protect against surface impacts, corrosion, fatigue, temperature extremes, moisture, internal pressure loads. They also feature high strength to weight ratios, dimensional stability, wear/chemical resistance, superior dielectric properties, ready machinability.

Typical Applications for Epoxy Matrix Tubing

• Bearings and collars
• Pressure tubing
• Bushings
• Impeder tubes
• Structural tubing

Wet winding process plays an important role in the manufacturing of tubing providing improved durability, flexural, tensile, compressive circumferential strength enabling usage in the electrical, aerospace, marine, defense, mining, oil/chemical processing, transportation industries. Unique Master Bond formulations are available for low CTE, high modulus cryogenic and aggressive tubing usage.
