Adhesive for mixed material bonding
2015 - PACE Award Winner
What: Flexible adhesive holds i3 together
Innovation: BMW needed to bond the i3's carbon fiber-reinforced plastic body to an aluminum chassis. Sika's adhesive flexes after curing, maintaining the bond as the plastic and aluminum expand at different rates with changing temperatures. The adhesive is still strong to withstand crashes.
