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

Michelman fibre sizings are available for a variety of application types and are said to dramatically improve fibre-polymer interface adhesion. These help industries including, automotive, transportation, construction, aerospace, energy, and sport improve the quality and performance of composites, according to the manufacturer.

Visitors to Michelman’s booth at JEC Forum this week will find a focus on Hydrosize Carbon, which is designed to allow carbon fibre manufacturers to optimise the interfacial adhesion between polymers and fibres by tailoring the surface chemistry of their reinforcement fibres to the chemistry of the matrix resin. Various grades are available and offer a wide variety of solutions depending on resin compatibility, fibre 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 suitable for fibre 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, the company adds.

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

The Hydrosize Carbon 400 Series include 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 has been developed to exhibit excellent thermal stability, mechanical properties, and low creep. It is especially suited for chopped carbon fibre applications.

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