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.

Ford F-150 Raptor, Nissan Pathfinder and Frontier, and Cadillac Blackwings | Autoblog Podcast #663

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by News Editor Joel Stocksdale and Associate Editor Byron Hurd. It's a packed show this week, and the three dive straight into the week's truck loads of news, starting with the unveiling of the Cadillac CT4-V and CT5-V Blackwing variants, followed by the 2021 Ford F-150 Raptor and the 2022 Nissan Pathfinder and Frontier. Next, they move on to what they've been driving. For Byron, that means more trucks. Lots and lots of trucks. Joel recently spent some time behind the wheel of a Bronco Sport, and the three discuss its merits as both an off- and on-road crossover. From this, they segue into a "Spend My Money" featuring Senior Producer Chris McGraw's neighbor, who acquired an older Forest Service Bronco and wants tips on what to do with it.  Autoblog Podcast #663 Get The Podcast iTunes – Subscribe to the Autoblog Podcast in iTunes RSS – Add the Autoblog Podcast feed to your RSS aggregator MP3 – Download the MP3 directly Rundown News 2022 Cadillac CT5-V Blackwing, CT4-V Blackwing bring big performance back to the brand 2021 Ford F-150 Raptor revealed, packing EcoBoost power, coil suspension and factory 37s 2022 Nissan Frontier enters the modern midsize truck world with big redesign 2022 Nissan Pathfinder debuts with fresh new duds, no more CVT What we're driving: 2021 Ford F-150 2021 Nissan Titan Pro-4X 2021 Toyota Tundra TRD Pro 2021 Ford Bronco Sport Spend My Money Feedback Email – Podcast@Autoblog.com Review the show on iTunes Autoblog is now live on your smart speakers and voice assistants with the audio Autoblog Daily Digest.
