BMW has been a big innovator in this area, with the i3 demonstrating cutting-edge techniques back when it debuted.

What GM is doing lines up nicely with a method pioneered by Boeing for airplanes. An epoxy resin combines with carbon fiber-infused plastic, creating an especially sturdy connection. The process involves high heat, so everything joins together properly. While GM’s method isn’t just like the super superglue Boeing created, it’s definitely similar.
