Abstract
The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project relates to the historic challenges associated with composite manufacturing, including long cycle times, poor recyclability, labor-intensive manufacturing, and energy-intensive curing processes. Thermoplastic composites have the potential to reduce cycle time, reduce labor requirements, and improve recyclability; however, traditional thermoplastic processes are energy intensive. This Phase 1 SBIR is seeking new, more efficient process heating methods that can be integrated into a continuous composite manufacturing process to improve production speed and reduce operating costs, enabling the growth of composite materials in weight sensitive industries that require high-volume, low-cost structural components, including automotive, unmanned aircraft, wind turbines, and cargo transportation. This Small Business Innovation Research (SBIR) Phase I project will determine the technical feasibility of ultrasonic heating and induction heating as an alternative to infrared heating in a continuous composite forming process. Process heating constitutes a significant portion of the direct energy consumed by in manufacturing. This is particularly true in the production of fiber-reinforced thermoplastic composites, where the polymer matrix must be melted as part of the consolidation process. As part of this Phase 1 project, heater modules for induction heating, ultrasonic heating, and infrared heating will be developed and integrated into a bench-scale, continuous composite forming prototype. Composite material will be produced using each heating method and energy consumption will be monitored during the forming process. The composite material produced during testing will be weighed and embodied energy will be calculated by dividing the total energy consumed by the mass of the material. The objective of this work is to identify a heating method that can reduce embodied energy by at least 40%, relative to the infrared heating system. This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
