Partners win Altair Enlighten Award for Toyota Tundra seatback design

BASF, Flex-N-Gate, Toyota, and L&L Products were awarded the prestigious Altair Enlighten Award for achievements in vehicle weight savings with the composite seatback design on the 2022 Toyota Tundra.

This is the second time in three years that BASF, L&L Products and Toyota have been recognised in the module lightweighting category.

“Pultrusion composite technology allowed us to design a seat structure that was 20% lighter compared to the previous model and to meet our cost goals,” said Vik Bhatia, Group Manager for Engineering Design Chassis at Toyota. “BASF, L&L Products and Flex-N-Gate were great partners that help us reach our targets.”

The seat structure is the first interior application for L&L Products’ Continuous Composite Systems (CCS) technology that uses BASF’s polyurethane pultrusion system Elastocoat 74850. CCS is a fibre-reinforced composite carrier with highly engineered sealants and adhesives in a two-dimensional profile. In this application it was overmoulded with BASF's impact-modified polyamide 6 Ultramid B3ZG7 CR to create the 3D shape of the 60% seatback.

“With this partnership, we were able to eliminate an all-steel assembly which contained 60 stamped and welded parts and integrate into four composite parts which reduced assembly and scrap costs associated with the metal seat structure,” said Hank Richardson, product engineering manager, L&L Products. “This also allowed for greater functionality of the seating system.”

“We continue to show how pultrusion can deliver lightweight, cost-effective solutions as well as integrated functionality,” said Kipp Grumm, Technology Leader for Thermoplastic Composites, Performance Materials, BASF Corporation. “The unique design of the injection overmoulded pultruded beam in the seat structure also passed all relevant crash test requirements and opens the door for more adoption of composites in automotive applications.”
