Rethinking Aerocomposites Manufacturing
Composites machinery specialist MTorres is trying to change the way aircraft OEMs fabricate and assemble large aircraft fuselage structures. Might this new method be the tool to fabricate next-generation aircraft? More.
Biocomposites On the Rise
In the composites and advanced materials industry, the most common reinforcing fibers are glass and carbon. However, in a marketplace that demands increased sustainability, biocomposite materials made from natural fibers and bio-based resins are making inroads, especially in the automotive market. According to Lucintel, the global biocomposites market is expected to grow 7.9 percent from 2018 through 2023, reaching an estimated $7.6 billion in value.
Composites and advanced materials have traditionally been used by OEMs that are looking to make vehicles lighter and therefore more efficient. However, over the next few decades, some experts anticipate that OEMs will need to push the envelope even further with parts that are not only lightweight, but also biodegradable.
“We need to be concerned about what happens with the material that you use in cars after their service life,” says Joshua Otaigbe, Ph.D., a professor in the School of Polymers and High Performance Materials at the University of Southern Mississippi, which will be exhibiting at CAMX 2018. “So if you have biodegradable components, they’ll get a useful life. Those materials can either be recycled, or they can biodegrade without harming the environment.”
Last summer, thanks to a $50,000 grant from the National Science Foundation’s I-Corps program, Otaigbe and doctoral student Shahab Rahimi developed a patent-pending cellulose-reinforced Nylon 6 material that is not only biodegradable, but also has mechanical strength and stiffness comparable to glass fiber composites. The researchers say the material could be applied to roofs, door panels and interior parts in automobiles, as well as rear decks, sidewalls and fenders in trucks and trailers.
Ford, BMW, Mercedes Benz and Jaguar already have interior products made with biocomposites, ranging from seat backs and door panels to carpeting and insulation. According to Deborah Mielewski, Ford’s senior technical leader for materials sustainability, biocomposites offer a wide range of benefits beyond biodegradability and weight. Unlike glass fibers, natural fibers don’t break during injection molding.
“Natural fibers tend to flow and bend and fill all the cracks and crevices where glass fiber does not make its way,” Mielewski says. In addition, glass fibers are less conducive to anisotropy (orientation in all directions) than natural fibers. “If our engineers got used to designing with natural fibers they would love it because they wouldn’t have to worry about all the directional shrinkage and directional reinforcement,” she adds.
Ford is currently developing a console for the Lincoln MKX that will incorporate both pulp and glass fibers into the composite, and Mielewski hopes that designers will use more biofibers as they learn more about them.
While biofiber-based composites are seen as the best solution to make products more sustainable, some companies, such as CAMX 2018 exhibitor Dixie Chemical, offer bio-based resins that could present a better option for OEMs. Alejandrina Campanella, the company’s thermoset and bio-based material platform leader, says it’s easier to work with plant oils, which are fairly consistent in their performance, than with biofibers, which can vary with environmental conditions.
In most cases the processes for manufacturing bio-based composites are no different than those for oil-based composites. “You may have to optimize your formulation, but that also happens if you’re using a resin made from oil,” says Campanella. Dixie generally sticks with palm oil, soybean oil and linseed oil or their fatty acids because of their pricing and availability.
Dixie currently produces two lines of bioresins; MAESO, derived from soybean oil, and MAELO, from linseed oil feedstocks. Like typical unsaturated polyester resins, they contain a reactive diluent such as styrene or vinyl toluene. However, Dixie also makes a methacrylated fatty acid (MFA) derived from palm, coconut and soybean oils, which can be used to replace all or some of the styrene or vinyl toluene. Using MFA reduces emissions and odors in the manufacturing process, and the MFA resins are tougher and less brittle than those made with styrene.
“We’re also working on a toughener made with soybean oil, which can be used for epoxies, vinyl ester and polyester resins. When we’ve compared it to products that are currently available in the market, it appears to have similar properties. This could have a really big impact,” says Campanella.
