Cooper Tire and BRDI consortium partners report significant progress on grant to develop guayule polymer for tires

Green Car Congress

Cooper Tire & Rubber Company, working as the lead agency in the grant, announced that its scientists have reached a key milestone toward the goal of producing, by mid-2017, a concept tire in which all of the natural and synthetic rubber is replaced by guayule-based polymers. The grant period ends in the second quarter of 2017.

PEM fuel cell X-ray CT study details effects of temperature and moisture on performance

Green Car Congress

Polymer electrolyte membrane (PEM) fuel cells require precise temperature and moisture controls to be at their best. Specifically, the researchers used synchrotron-based micro X‐ray computed tomography (CT) to visualize and to quantify the water distribution within gas diffusion layers subject to a thermal gradient. —Shum et al.

Harvard researchers develop tough, self-healing rubber

Green Car Congress

Self-healing materials aren’t new—researchers at SEAS have developed self-healing hydrogels, which rely on water to incorporate reversible bonds that can promote healing. Rubber is made of polymers often connected by permanent, covalent bonds. These two types of bonds are intrinsically immiscible, like oil and water, said Cai.

UBC engineers use fiber from recycled tires to develop more resilient concrete

Green Car Congress

University of British Columbia (UBC) engineers have used polymeric scrap tire fibers (STF) to develop a more resilient type of concrete that could be used for concrete structures such as buildings, roads, dams and bridges, while reducing landfill waste. A paper on the work is published in the journal Materials and Structures. Onuaguluchi, O.
