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.

Earthquake causes most of Toyota's Japan operations to shut down

Toyota is idling a large portion of its Japanese assembly plants as a result of the devastating earthquake in Hokkaido, Japan. The earthquake had such a big effect on the carmaker's supply chain that a number of its plants will have to be shut down for an undisclosed period, starting on Saturday. The 6.7 magnitude earthquake occurred early on September 6 th, resulting in more than dozen casualties and hundreds of injuries, cutting power to the entire island; the powerplant supplying half of the island's power was located so close to the earthquake's epicenter that it shut down automatically, bringing down the rest of the island's grid with it. Tens of people were also reported missing, as reported by Reuters. The affected factories are the Kyushu, Tahara and Toyota Auto Body plants, according to Automotive News, and they manufacture vehicles such as different Lexus models and the Toyota Land Cruiser. Some of the models produced in these factories are exported to the United States, but a Toyota spokesman said that North American operations are not likely to be significantly affected by the plant closures. As well as the automobile assembly plants in Hokkaido, Toyota also has a facility there that manufactures transmissions and transfer cases. As it was also without power, Toyota could not confirm when the plant would be back online. Out of Hokkaido's 2.95 million households, 1.54 million had regained power by Friday afternoon. All in all, Toyota has 18 manufacturing facilities in Japan; spokeswoman Akito Kita said that from Monday on, the shutdown will affect all Japanese Toyota and Lexus lines — not including two Daihatsu facilities that are also used for Toyota products. The shutdowns come directly after Toyota also announced a recall for Japanese-built hybrid models, mainly Prius. Related Video:

Fuel cells will flop outside Japan, says VW

"It may fly within Japan, but not globally," VW's Shoji said.
It's long been battered into our beleaguered auto writer brains that the ultimate future source of motivation for tomorrow's cars and trucks is not gasoline, diesel, electricity, natural gas, propane or solar power - it's the hydrogen fuel cell. It's been the Next Big Thing since the start of Next Big Things.
