TECHNOLOGY REPORT
Future of Lightweighting: WEAV3D, Braskem and Clemson Composites
Center developed a composite lattice-reinforced polypropylene sheet that
reduces cost by 50% and weight by 23% compared to CFPA6 organosheet.
Runner-up: Carsolia Composites introduced a patent-pendEnabling
Technology: CompositeEdge's EcoFiber AFP structures utilize
natural fiber composites blended with plastic for body panels, interior
trims, chassis and suspension parts.
using less energy, the new sheet reduces cost by 50% and
weight by 23% compared to CFPA6 organosheet (nylon 6)
and weighs between 60-70% less than steel. The process also
results in a 62% reduction in trim scrap by weight. Compared
to steel, the polypropylene sheet reportedly displays better
energy absorption and shape recovery.
" Our line of sight to first production is likely model year 2026,
production [commencing] at the end of next year, " Lewis Motion,
founder and CEO of WEAV3D, said at the MBS conference. " The
more we can get people to design with the approach that we
have, the more beneficial it can be used throughout the vehicle -
not just as closures but even things like the battery box. "
ing composite coil spring that's 50% lighter than steel. The
carbon fiber composite material also has 50% less CO2 equivalent
per kilogram vs. steel, resulting in a 75% overall reduction
of CO2 emissions. Carsolia claims it can incorporate variable
thicknesses for tuned spring rates during compression
range and that its production process can support high-volume
vehicle production.
Sustainable Product
Winner: DuPont BETAMATE broad bake adhesive technology
helps reduce energy use and greenhouse gas emissions during
vehicle body manufacturing by allowing adhesives to cure
at about 25°C lower temperatures, thus saving energy via reduced
e-coat oven temperatures and shorter oven cycle
times. The technology also eliminates the need for cold storage
thanks to a special formulation that extends shelf life.
Runner-up: Bridgestone Americas manufactures the Turanza
EV grand touring tire with 50% renewable and recycled materials
- one of the highest percentages
among commercially
available replacement
tires - and features
Bridgestone ENLITEN technology
to optimize performance
and improve life span.
Bridgestone is aiming for all
its tires to be composed of
100% renewable and recycled
materials by 2050.
The Altair Enlighten Awards were presented at the 2024 CAR Management Briefing Seminars in Traverse City, Michigan.
