Solvay SA The fuel intake runner used in the Polimotor 2 all-plastic engine.
3-D printed, reinforced polyetheretherketone was chosen for the fuel intake runner in the Polimotor 2 all-plastic vehicle engine project.
Solvay Specialty Polymers says a special grade of its KetaSpire PEEK with 10 percent carbon fiber loading allows replacement of the original aluminum runner for a 50 percent weight saving. PEEK resists automotive fuels and gives reliable mechanical performance at continuous-use temperatures of up to 464 degrees F.
Arevo Labs of Santa Clara, Calif., 3D prints the runner using its reinforced-filament fusion platform and process control software to optimize mechanical properties of the component.
“With this runner, we see one of the very first carbon fiber-filled PEEK parts to be fabricated with the additive manufacturing process,” says Brian Baleno, global automotive business manager for Solvay Specialty Polymers.
Polimotor 2 is the brainchild of auto innovator Matti Holtzberg, who wants to build an all-plastic, four-cylinder engine that weights between 138 to 148 pounds, about 90 pounds less than a standard production engine. The new engine is destined for competitive racing in 2016. Holzberg also is president of Composite Castings LLC of West Palm Beach, Fla.
