Demonstration of Minimally Machined Honeyco Silicon

This includes an Ultracor raw material cost of about $97,000/m 2, and a Trex silicon carbide deposition cost of $27,000/m2. Even at double this price, HoneySiC would beat NASA’s goal of $100,000/m 2. Cost savings are estimated to be 40 to 100 times that of current mirror technologies. The organic, rich prepreg material has a density of 56 kg/m3.
