Army Research Laboratory scientists developed a diffusion-enhanced adhesion process which is expected to significantly improve the performance of multifunction hybrid composites. NASA engineers estimate that composites made using the new process will result in savings in space exploration projects. The cash flows for one project are estimated. Determine the rate of return per year.
