Tougher than steel: Wood pulp could make lighter auto parts

KYOTO, Japan — The global push among carmakers to make ever lighter vehicles is leading some auto suppliers in Japan to turn to what seems like an unlikely steel substitute — wood pulp. Japanese researchers and auto component makers say a material made from wood pulp weighs just one-fifth of steel and can be five times stronger. The material - cellulose nanofibers — could become a viable alternative to steel in the decades ahead, they say, although it faces competition from carbon-based materials, and remains a long way from being commercially viable.> Related: Jay Leno drives the Renew cannabis car — hemp you can't dent Reducing the weight of a vehicle will be critical as manufacturers move to bring electric cars into the mainstream. Batteries are an expensive but vital component, so a reduction in car weight will mean fewer batteries will be needed to power the vehicle, saving on costs. "Lightweighting is a constant issue for us," said Masanori Matsushiro, a project manager overseeing body design at Toyota. "But we also have to resolve the issue of high manufacturing costs before we see an increased use of new, lighter-weight materials in mass-volume cars."A NEW PROCESS Researchers at Kyoto University and major parts suppliers such as Denso Corp, Toyota's biggest supplier, and DaikyoNishikawa Corp, are working with plastics incorporated with cellulose nanofibers — made by breaking down wood pulp fibers into several hundredths of a micron (one thousandth of a millimeter). Cellulose nanofibers have been used in a variety of products ranging from ink to transparent displays, but their potential use in cars has been enabled by the "Kyoto Process," under which chemically treated wood fibers are kneaded into plastics while simultaneously being broken down into nanofibers, slashing the cost of production to roughly one-fifth that of other processes. "This is the lowest-cost, highest-performance application for cellulose nanofibers, and that's why we're focusing on its use in auto and aircraft parts," Kyoto University Professor Hiroaki Yano, who is leading the research, told Reuters in an interview. The university, along with auto parts suppliers, are currently developing a prototype car using cellulose nanofiber-based parts to be completed in 2020.

Jay Leno brings a rotary-powered VW Beetle to the garage

It takes something really unique or inventive to pique Jay Leno's interest. His show, Jay Leno's Garage, has featured everything from concours-worthy classics to completely custom, home-built machinery. How do you get Leno to feature one of more than 20 million Beetles on his program? Stick a turbocharged rotary engine under the hood. The Beetle's owner, Mario Markakis, swapped the car's stock flat four-cylinder for the Wankel engine from a 1990 Mazda RX-7 Series 5 Turbo. The engine's 250 horsepower are fed through a reinforced version of the Beetle's stock four-speed transmission. That's about five times the original engine's output. It works well, with the car putting down some impressive times at the drag strip. Markakis did most of the work to the Beetle in his garage. In addition to the engine swap, he's modified the car's brakes, suspension, and interior. Check out the video to hear all the details of this custom Wankel-powered Volkswagen.

Hiss off! Venomous snake takes refuge in Australian man’s engine bay

A man who went out for a walk in suburban Sydney got quite a surprise when he returned to his red Mazda. Left on his windshield was a hand-written note warning him that a venomous red-bellied black snake had taken up residence in his car. "Hi," the note read, "this afternoon a red Belly slithered up into your front left tyre. Please be careful." The snake is a native of wet areas of eastern Australia that can grow up to 2.5 meters (about 8 feet), making it one of Australia's largest venomous snakes. They're considered dangerous, but shy, unlikely to bite unless severely agitated. When Michael Garbutt popped the hood, he found the snake coiled up inside in the corner. "To say I was shocked is an understatement," he told The Sydney Morning Herald. "On reflection I don't think I would have put my hand out to pop the bonnet if I had known it was there." So he took to Google to look for a local snake wrangler and found Andrew Melrose, of Shire Snake Catchers. By the time he arrived, the snake had moved down into the engine. Then it moved behind the wheel guard, and then under the engine to the front bumper, then back to the right front wheel. Melrose said he coaxed it out by gently touching its body. "I've done it my whole life," he said. "It looks simple but if you haven't done it before you can get killed real quick." In the end, Melrose ended up grabbing the snake from the ground outside of the car and dropping it in a bag. The whole de-snaking process took about an hour. Melrose said the snake is common on the swampy peninsula area where it was found, since it finds plenty of frogs, eels and other creatures to eat. He says it's common to find them in cars. "If they get startled they look for the first place that is safe," he said. "The place I found it was very bare. There was no place for the snake to escape. People would have startled it and the only place for it to hide was the car. The driver could have driven off unaware and parked and the snake would have left the car when it felt safe." So let this be a lesson for you, Autoblog readers: familiarize yourself with your local venomous snakes. And keep the number of your local snake wrangler handy at all times. Or just don't move to Australia.Related Video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
