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.

Customers want wireless charging in next-gen Prius Plug-In; they might get it

Could 2016 be the year prospective Toyota Prius Plug-in Hybrid buyers are waiting for? Why, yes, says an unidentified Toyota spokesman. That's according to Plug-in Cars, which reports that a wireless plug-in vehicle charging system may be less than two years away for the Prius Plug-in. WiTricity has, for a few years, been developing its magnetic resonance wireless charging system for the model. This type of system allows for more distance leeway than other wireless setups when it comes to how close the car and its on-board receiver need to be to the floor-mounted system. That allows for smaller, lighter on-board receivers, which is key for any plug-in vehicle. Toyota spokeswoman Jana Hartline confirmed in an e-mail to AutoblogGreen that the company has conducted wireless charging tests in Japan "with hopes to bring that technology to market in the near future" but declined to provide more detail on the company's plans to offer wireless charging for plug-ins. Toyota's Satoshi Ogiso said last summer that the Prius Plug-in would eventually offer a wireless charging system in response to prospective customers' demand for it, though he wasn't specific on a time frame. Toyota started discussions with WiTricity regarding wireless charging system development more than three years ago and said late last year that it had reached a licensing agreement with the Boston-based company. WiTricity has also worked on developing wireless-charging systems that are compatible with Audi and Mitsubishi vehicles. WiTricity grew out of MIT back in 2007, back when we could barely imagine how it would work.
