I’ve heard of several new plastics that make excellent metal replacements. But concrete? That’s a first for me. A hydrogen-rich polymer loaded with boron actually can replace concrete as neutron-shielding material in nuclear power plants or nuclear submarines. The new Quadrant EPP material is currently available in machinable 1-inch x 48-inch x 96-inch plates. Borotron HD050 is a high-density polyethylene (HDPE) enhanced with 5 percent elemental boron to provide extra shielding against neutron radiation. The combination of boron within a matrix of HDPE, a naturally hydrogen-rich material, targets nuclear shielding applications. Hydrogen-rich materials attenuate neutrons extremely well and boron has an affinity for absorbing thermalized neutrons. Potential uses include shielding for radiation therapy rooms, where the product in plate form is integrated into the wall structure. Other application areas include nuclear research centers, nuclear power plants, power generation areas in nuclear submarines, production areas for nuclear detection devices and the equipment itself, and spacecraft exposed to radiation. Borotron HD050 plate is lighter than some other neutron shielding materials such as concrete, and easier to work with in construction than other options including water. The formulation was engineered by Quadrant Engineering Plastic Products (Quadrant EPP).
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
As we saw on the show floor this week at the Pacific Design & Manufacturing and co-located events in Anaheim, Calif., 3D printing is contributing to distributed manufacturing and being reinvented by engineers for their own needs. Meanwhile, new fasteners are appearing for wearable consumer and medical devices and Baxter Robot has another software upgrade.
