Scientists at the State University of New York’s College of Environmental Science and Forestry are developing a way to add wood fiber to plastic to make it stronger. The process extracts nanocrystals of cellulose out of woody materials such as trees and willow shrubs and mixes them with the plastic. The result is a strong, lightweight plastic that will degrade in a landfill.
“By adding an ounce of crystals to a pound of plastic, you can increase the strength of the plastic by a factor of 3,000,” says William Winter, chemistry professor and director of the college’s Cellulose Research Institute. “And in the end, in a landfill, it’s just carbon dioxide and water, which can be taken up and made into more biomass.”
Design collaboration now includes the entire value chain. From suppliers to customers, purchasing to outside experts, the collaborative design team includes internal and external groups. The design process now stretches across the globe in multiple software formats.
A new high-pressure injection-molding technology produces near-net shape parts with 2-inch-thick walls from high-performance materials like PEEK, PAI, and carbon-filled polymers. Parts show no voids, sinks, or porosity, have more consistent mechanical properties, and are stronger.
