Michelman introduces line-up of fiber sizings that improve performance of carbon-fiber composites

Michelman will introduce visitors to the JEC Forum Chicago Conference & Business Meetings to its portfolio of fiber-sizing solutions that help industry exploit the benefits of composites: Design freedom, consolidation of parts and integration of functionality while meeting lightweighting initiatives.

Fiber sizings are an important enabler for carbon-fiber composites.

Michelman fiber sizings are available for a variety of application types, and improve fiber-polymer interface adhesion. These assist industries, including automotive, transportation, construction, aerospace, energy and sport, in improving the quality and performance of composites.

Visitors to Michelman’s booth #113 will find a focus on Hydrosize Carbon, which allows carbon-fiber manufacturers to optimize the interfacial adhesion between polymers and fibers by tailoring the surface chemistry of their reinforcement fibers to the chemistry of the matrix resin. Various grades are available and offer a variety of solutions depending on resin compatibility, fiber type and desired composite performance.

Designed for polyamides, including high-temperature applications, the Hydrosize Carbon 200 Series is APE-, solvent- and VOC-free and is perfect for fiber-reinforced nylon composites where greater thermal stability is required. Coolant pumps are a typical automotive application. Other benefits of these small-particle-size dispersions include excellent film-forming properties and high strand integrity.

Formulated for polycarbonates (PC) and other PC blends such as PC-ABS, the Hydrosize Carbon 300 Series produces good chemical resistance along with interfacial adhesion to polymer systems. Appropriate applications include laptop cases or other electronic components.

Their Hydrosize Carbon 400 Series includes high-performance grades that can withstand the extreme processing temperatures that many high-temperature thermoplastics require. Appropriate materials include PEEK, PPS, PEI and others used to produce various composite engine components. This series exhibits excellent thermal stability, mechanical properties and low creep. It is suited for chopped carbon-fiber applications.

The Hydrosize Carbon 700 Series is formulated to improve the performance of carbon-fiber-reinforced vinyl ester composites and is perfect for under-the-hood applications. Its proprietary chemistry allows for increased adhesion between the carbon fiber and various vinyl ester compounds.

The JEC Forum is taking place June 19 and 20, 2019, at the Aon Grand Ballroom at Navy Pier in Chicago.
