Miloaga says JM has been working with the Royal Oak, Mich., U.S. offices of Forward Engineering GmbH (Munich, Germany), a global transportation design and engineering consultancy specializing in lightweight polymer, composites and multi-material solutions. The company — which has particular expertise designing battery enclosure systems as well as providing battery-enclosure-specific prototyping, testing and validation — ran comprehensive mechanical and crash simulations on JM’s all-thermoplastic enclosure design. This, in turn, defined specific layups for advanced material card development for use in crash simulations to support application-specific customer projects. As was reported in Part 1, there is considerable need in the auto industry for accurate material cards on composite materials, particularly those with discontinuous reinforcement.

Mitsubishi Chemical Group Corp. (MCG, Tokyo, Japan) produces a variety of composite technologies. These include acrylonitrile and polyacrylonitrile (PAN) carbon fiber precursor, carbon fiber itself, carbon fiber intermediates, thermoplastic and thermoset semi-finished products and molded parts. On the thermoplastics side, the company offers injection moldable short glass PP and ultrashort carbon fiber-reinforced engineering resins; compression moldable GMT/organosheet reinforced with either fiberglass or basalt and with PP, PA6 or PA6/6 matrices; and recycled thermoplastics and carbon fiber -reinforced thermoplastics produced with a novel dry impregnation technology. On the thermoset side, the company produces carbon, glass, aramid and hybrid fiber-based UD tapes, woven fabrics, prepregs and towpregs in a variety of resin systems, as well as carbon fiber -reinforced SMC (CF-SMC) and split-tow CF-SMC with enhanced moldability. In addition to recycling thermoplastics, MCG also recycles carbon fiber in Europe and Japan, which is subsequently milled, chopped and compounded, or made into nonwovens or veils . The group’s advanced composites molder produces thermoset carbon composite components for the premium automotive, motorsports and aerospace industries. Additionally, an engineering services group develops materials cards on thermoplastic composite materials for use in simulation work on applications like battery enclosures.
Many Mitsubishi materials are used on composite EV battery enclosures globally, including its GMT and GMTex materials, which are used on Japanese and European EVs and have been evaluated as battery protection plates to help safeguard battery modules and passenger compartments from impact damage.

“We see the materials mix changing as the value chain increases collaboration on the design of EV battery packs and their individual components,” explains Dhanendra Nagwanshi, SABIC senior business manager – automotive marketing-polymers. “We see flame-retardant thermoplastics potentially becoming a larger share of the mix because they can offer tremendous advantages, including inherent thermal and electrical isolation, intumescent qualities, lightweighting, parts integration and potentially parts elimination, which supports cost reduction. Additionally, they’re recyclable, reusable and they lower environmental impact — not only through weight savings but also by lowering greenhouse gas emissions roughly 10-15% as verified by LCA studies. The future is bright for thermoplastics in the EV battery space.”
One area his team is working on involves battery trays. “Trays are harder because of their weight, complexity and structural requirements,” Nagwanshi continues. “We’ve done teardown feasibility studies and have seen 60-kilogram weight and 50% cost reductions by realizing the benefits of hybrid systems, where cooling channels are integrated into the tray, which, in turn, is optimized not only for cooling but to fit in the available packaging space. Thermoplastic composites not only reduce weight significantly and improve FR and thermal efficiency, but they also reduce the risk of electrical shorts and high-voltage shocks. Given concerns about the possibility of sharp objects puncturing the bottom of the tray, allowing electrolyte to spill out and potentially cause a fire, we’ve evaluated different ribbing, fiber and FR combinations and even looked at hybrid systems with metals to keep trays protected. Right now, the whole industry is trying to understand which materials work for which chemistries and geometries. Everyone is looking at everything and everything is on the table.”
