Auto manufacturers like Lamborghini, Ferrari, Aston..etc..etc...have been using adhesives instead of welding for years in some areas where it's just impossible to weld. Areas where CF and steel/aluminum meet for example, where a bolted connection would be weaker and add weight.
What do you think holds carbon fiber components together. CF is just a piece of fabric without the epoxy (or adhesive) that keeps it stiff. It's not a difficult concept to wrap your head around. NASA uses high strength adhesives for god's sake. With all that though, they have limitations and are susceptible to extreme temperature changes.
