Abstract: A method prepares a curable composition based on ground composite material from the recycling of discarded composite elements such as old pipes or rotor blades of wind power plants. The ground composite material allows for the replacement of virgin short glass fibers and fumed silica commonly employed in such compositions used as structural adhesives essentially without any negative impact on the performance.
