An ultra lightweight concept car from Toyota is making its North American debut this morning at the 2008 Chicago Auto Show. The body frame is made from carbon-fiber reinforced plastic (CFRP), the same material used in the Boeing Dreamliner fuselage and wings. Toyota says the CFRP material “is lighter and stronger than traditional metals, creating a shock-absorbing like structure with cross-sections that help absorb energy during an impact.” Its curb weight of 926 pounds is one-third the weight of the Prius hybrid. Metal is also replaced in the roof of the concept car. The 1/X is made from a bioplastic derived from kenaf and ramie plants. “The result is a roof that improves heat insulation, emits less carbon dioxide, increases the amount of light entering the cabin, and reduces noise,” says the Toyota announcement. Ramie is a fibrous plant native to eastern Asia. This is the first time I’ve heard of it being used in plastics. Kenaf has been under study as reinforcement in plastics for more than a dozen years. Toyota has been a leader in developing biplastics in recent years, but the 1/X announcements leaves many questions unanswered. What is the plastic used in the “bioplastic”? kenaf and ramie are reinforcing and filler media. Is it PLA, a PLA hybrid, or something else? What are the body panels made of? Is CFRP practical as a material of construction in cars, or is this just a great PR model? High cost and tight supplies of CFRP could limit its widespread use in cars. Are there any unique glazing concepts in the 1/X?
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.
