Lubrizol has developed a thermoplastic polyurethane (TPU) urethane that targets replacement of silicone in peristaltic pumps. Peristaltic pumps are positive displacement pumps used to pump a variety of fluids. A technical officer of Lubrizol interviewed at MD&M West in Anaheim, CA yesterday said that the new TPU is melt processable, unlike silicone, which is a thermoset. The new material would be one of the softest TPUs with Rockwell Hardness of 62A. The product was on display at the Lubrizol booth. Full details are expected to be disclosed at the Annual Technical Conference (ANTEC) of the Society of Plastics Engineers in Boston this May.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
Lawrence Livermore National Laboratory and MIT have 3D-printed a new class of metamaterials that are both exceptionally light and have exceptional strength and stiffness. The new metamaterials maintain a nearly constant stiffness per unit of mass density, over three orders of magnitude.
Smart composites that let the material's structural health be monitored automatically and continuously are getting closer to reality. R&D partners in an EU-sponsored project have demonstrated what they say is the first complete, miniaturized, fiber-optic sensor system entirely embedded inside a fiber-reinforced composite.
