Using a variety of metallic fibers and
particles, these compounds have densities
similar to traditional metals, while offering
design and processing flexibility because of the
polymer matrix, which can be extruded, molded,
calendered, or thermoformed into the final
desired shape.
KEY CHARACTERISTICS
The primary features and benefits of Gravi-Tech
formulations are:
• Customized density, offering a wide range
of specific gravities from 1.2 to 11 gm/cm3
• Broad modulus range, from very flexible
to very rigid grades
• Corrosion resistance, withstanding oxidation
for long-term use and benefit
• Chemical resistance, withstanding fuels, oils
and other harsh chemicals
• Metallization and electroplating, delivering
the look and feel of metal
Additional features include:
• Design flexibility and processing ease
• Good impact strength
• Elevated heat deflection temperature

The automated pultrusion process fabricates continuous glass or carbon fiber-reinforced, constant cross-section profiles with consistent, uniform properties.
For the brace, Avient's engineering team developed and analyzed three options: a unidirectional, hybrid carbon and glass fiber profile; a unidirectional carbon fiber profile; and finally, a profile made with both a unidirectional carbon fiber and a transverse engineered fabric, which had the advantage of minimizing any potential cracks from propagating.
The third profile was also 41% lighter than aluminum, with a 50% increase in flexural stiffness, and maintained torsional rigidity slightly better than that of aluminum.
