TPI Composites and University of Tennessee Knoxville Advance the Creation of Glass Fiber Yarns from Recycled Wind Turbine Blades
13 Septembre 2023 - 10:05PM
TPI Composites, Inc., (TPI) (Nasdaq: TPIC) announced today that it
has moved to the second phase of development with the University of
Tennessee Knoxville (UT) in creation of glass fiber yarns from
end-of-life wind blades. The completion of the second phase will
create new opportunities for materials reclaimed from
decommissioned blades.
The recycled materials enable higher value intermediate forms of
glass fiber and create a viable market that is both environmentally
and economically sustainable. The current challenge of recycled
glass fiber is that applications for randomly oriented
discontinuous fiber are generally limited to non-structural
components or thermal insulation where the value is significantly
lower than the cost of recovery. Steve Nolet, TPI’s Senior Director
of Innovation and Technology said, “Phase I focused on using simple
hand operated textile methods; after multiple trials with varying
fiber length, twist rate, and mechanical testing we learned the
importance of hybridization with synthetic polymer fiber.”
In Phase II, the UT team will use industrial textile
manufacturing methods and equipment to scale the process and focus
on ideal filament length, ratio of glass to synthetic fiber, and
other process variables that optimize the properties of the
recycled yarn. With additional scaling of prototype yarns,
downstream processing including conversion to woven and non-woven
broad goods or filament wound plates will be accomplished. These
materials will then be processed with commercial resins to
formulate composite plates for mechanical testing. Generating
material properties of different composite configurations will
identify applications appropriate for the recovered materials.
“The project plays a major role at the UT Fibers and Composites
Manufacturing Facility, with the collaboration on composites
recycling being an area of global importance,” says Dr. Uday
Vaidya, UT-ORNL Governor’s Chair Professor and Chief Technology
Officer for IACMI-The Composites Institute. “This project is a
unique opportunity for UT graduate and undergraduate students to
explore the science and engineering aspects of value-added recycled
glass fibers for next generation sustainable solutions.”
