Michelman presents Effect of Sizing on the Interfacial and Mechanical Properties of Carbon Fiber (CF) Reinforced Polyamide (PA6,6) Composites at CAMX 2019

CAMX2019Michelman, known for its interfacial adhesion expertise and production of industry-leading Hydrosize® fiber sizing and surface treatments, will feature its new line of Hydrosize® Carbon solutions that allow customers to take advantage of carbon fiber’s unique benefits and produce higher quality composite parts. Hydrosize® Carbon, 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.

The Hydrosize® Carbon brand offers a wide 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 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.

The 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 especially suited for chopped carbon fiber applications.

Finally, the Hydrosize® Carbon 700 Series, currently under final stages of development and formulated to improve the performance of carbon fiber reinforced vinyl ester composites, is targeted for SMC applications. Its proprietary chemistry allows for increased adhesion between the carbon fiber and various vinyl ester compounds.

Mr. Steve Bassetti, Group Marketing Director, and Mr. 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 fiber, look for their presentation to demonstrate the effects of fiber surface-treatment and sizing on the interfacial and mechanical properties of carbon fiber/nylon (PA6,6) composites.
