Stiffer is Better: The Case for Carbon Fiber Filled Thermoplastics
Philip Schell, Executive Vice President, Carbon Fiber, Zoltek
Carbon fiber as a reinforcement provides significant advantages over traditional glass fiber reinforcement including higher strength and modulus of the resulting compound. A review of carbon fiber markets, technology and products for reinforcing thermoplastics from high temperature resins to polypropylene will be presented and discussed. The various forms of carbon fiber from continuous tow to milled fiber provide different levels of performance in a thermoplastic.

A Novel High Performance Chopped Strand Glass Fiber for Reinforcing Polypropylene – ThermoFlow® 641
Derek Bristol, Research Associate, Johns Manville
Johns Manville (JM), a market-leading manufacturer of continuous filament glass fiber and a Berkshire Hathaway company, recently announced the introduction of a new chopped strand: ThermoFlow® 641 for reinforcement of polypropylenes. ThermoFlow® 641 delivers exceptional composite mechanical properties in polypropylene and is designed to perform in detergent resistant applications, such as washing tubs in appliances. The combination of novel sizing chemistry, and process improvements, has resulted in a chopped strand glass fiber that improves the interface between the glass and resin. Benefits include better composite mechanical properties both as-molded and after hot/wet aging, reduced yellowness in the composite, excellent flow and bundle durability during feeding, and improved performance at low levels of coupling agent.

BioComposites: Design, Testing, and Engineering
Trey Riddle, CEO, Sunstrand LLC
Due to interest in sustainable materials, natural fibers are increasingly being utilized in composite materials. In many commercial applications, very short natural fibers are being used primarily as fillers to achieve a ‘greener’ product. While these types of applications reduce plastic content in consumer goods, and generally require lower energy during production, they are not realizing the true potential of natural fibers as an engineered reinforcement material. Recent advances in natural feedstock processing have yielded fiber forms which can be used to replace glass fibers in many reinforced plastic applications. Moreover, natural fiber composites have been found to offer benefits such as reduced weight and costs. Generally speaking, the high specific modulus of natural fibers often enables reduced weight parts which can be designed to match glass fiber composite stiffness. An introduction to these materials, as well as their benefits and challenges, will be offered and substantiated. Test data on natural fibers and natural fiber reinforced composites will be presented illustrating the competitive nature of natural fiber composites. Details will be given on the compatibly and processing variations when utilizing natural fibers in common manufacturing processes such as infusion, layup, and various molding compounds. Examples will be presented which illustrate property matching and design considerations between glass and natural fiber composites.

An Introduction to Mafic and Basalt Fiber
Jeff Thompson, Head of Sales and Marketing , Mafic
Basalt fiber has long been of interest to the composites community for its potential for high strength, stiffness and low cost but it has been plagued by inconsistency. Mafic will introduce the fulfilment of that potential with its entrance into the market and its focus on quality, consistency and reliable production here in the US. In addition, Mafic will lay out the benefits of basalt fiber products, and how they can unlock weight and cost savings in composites.
