Michelman, known in the fibres and composites industry as the interface adhesion expert and manufacturer of Hydrosize fibre sizings, will feature its new line of Hydrosize Carbon at CAMX 2019 in Anaheim, CA, in September.

Hydrosize Carbon solutions are designed to allow customers to leverage carbon fibre’s unique benefits and produce higher quality composite parts. This is done by tailoring the surface chemistry of the reinforcement fibres to the chemistry of the matrix resin, thereby optimising the interfacial adhesion between the polymers and the fibres.

This diverse range of grades offers a wide variety of solutions depending on resin compatibility, fibre type, and desired composite performance, according to the manufacturer.

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. 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. The Hydrosize Carbon 400 Series includes high-performance grades that can withstand the extreme processing temperatures that many high-temperature thermoplastics require.

Finally, the Hydrosize Carbon 700 Series, currently under final stages of development and formulated to improve the performance of carbon fibre reinforced vinyl ester composites, is targeted for SMC applications.

Steve Bassetti, Group Marketing Director, and Muhammad Iqbal, Research Chemist, from Michelman’s Industrial Manufacturing Group, are presenting a technical paper entitled Effect of Sizing on the Interfacial and Mechanical Properties of Carbon Fiber (CF) Reinforced Polyamide (PA6,6) Composites.

As there is a lack of literature on experimental and direct determination relating micromechanical properties, such as interfacial shear strength to the macro-mechanical performance of composites containing sized or un-sized carbon fibre, their presentation will demonstrate the effects of fibre surface-treatment and sizing on the interfacial and mechanical properties of carbon fibre/nylon (PA6,6) composites.
