The manufacturer of continuous filament glass fiber will showcase advanced composites technology at JEC World 2019 in Paris, including OS-6 series and the new NCF-6 and CR-6 series for structural thermoplastic composites and MultiStar 266 rovings for sheet molding compounds (SMC) reinforcements where white or light-colored SMC composites is needed.

Johns Manville introduces advanced composites for structural thermoplastic composites
OS-6 series is an AP Nylon Composites Sheet reinforced with continuous woven fabric and impregnated using JM proprietary technology with complete fiber impregnation to enhance impact resistance, strength, and stiffness in thermoplastic composites.

The new CR-6 series combines formability with excellent impact resistance through a chopped roving (CR) reinforcement. This innovative product enables a range of high formability applications for thermoplastic sheets with quasi isotropic properties.

The new NCF-6 series is reinforced with high-density continuous non-crimp fabric not conventionally possible with organosheets. This product will offer superior strength, stiffness and impact resistance in structural applications.

Matthew Walp, Composites Business Leader at Johns Manville says:

“JM is creating a platform of nylon thermoplastic composite sheets using our innovative in-situ polymerization technology. In addition to our OS-6 series introduced in years past, our new CR-6 and NCF-6-series increase design flexibility by providing product designers a collection of materials to realize light-weighting that will expand the use of composites in automotive and other light-weighting markets. Our thermoplastic composite sheets combine exceptional properties, short cycle times, and recyclability at a cost that will drive increased adoption of composites”

MultiStar 266 is used in low-shrink SMC applications based on polyester resin where high quality surface appearance is required with a homogeneous outlook. This requirement is important in sanitary applications, mass transportation (bus and train), building and electrical applications. SMC composites are durable, recyclable and can save 30% to 50% of CO2 emissions during the life-cycle compared to steel.

MultiStar 266 Roving

Karin Demez, Global Marketing and Portfolio Leader in JM’s Engineered Products, Global Fibers business says:

“The improved performance of MultiStar 266 Roving allows SMC compounders to expand the use of composites in new applications where composites parts do not need to be coated, thus eliminating the energy intensity steps of painting with significant high volatile organic compounds (VOC) emissions. Stationary non-painted SMC applications reduces up to 50% energy use, CO2 emissions, ozone and acid rain water vs. competing materials during its life-cycle“

The products will be on display at JEC World 2019 composite show in Paris. The JM booth is at Hall 6 – G32.
