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.

Toyota Prius gets higher clearance, better suspension in Pakistan

It's been 16 years since the Toyota Prius launched in Japan. Finally, the world's most popular hybrid is becoming the first hybrid car to show up in Pakistan. This version of the Prius has been customized by Indus Motor Company (IMC) in order to deal with, well, let's just say some challenging road conditions. IMC knows what it's doing, and has modified Toyota and Daihatsu vehicles for the Pakistani market for over 20 years. The Prius brings with it the iconic shape and Parvez Ghias, CEO of IMC, told The Technology Times that the car's arrival, "is indeed a great milestone, not only in the history of IMC, but, of the entire nation." Pakistan Today says that IMC is beefing up the ground clearance of the imported Priuses and adds a "robust suspension system." Why would this be important? Well, the US Department of State warns travelers to beware of crowded roads, aggressive and poorly trained drivers and bad roads that could include potholes and sharp drop-offs. Then there's the "donkeys, cattle, horse carts, and even the occasional camel [that] can pose roadside hazards in some areas." There's also the big problem of terrorism-related violence in Pakistan, but we haven't heard that the Pakistan Prius has been bullet- and shrapnel-proofed.
