- Description
- MODIFICATION #3: PROVIDE ANSWER TO QUESTION Q2: Q2: "Would a nickel plated carbon fibre mirror be acceptable?" A1: "The use of carbon fiber composite material as a large mirror substrate has been in development in for a number of years. While a few specialized applications have been able to make use of this technology, it has not yet been widely adopted because of several difficulties inherent in the materials used and construction methods. Some of these problems include the anisotropic behavior of the fiber and composite material under both thermal and moisture (humidity) variations. The vendor mentions nickel plating, which has been used to "seal" the material to reduce the humidity effects, but since we will be using this mirror in humidity conditions that easily range from near 0% to 100% relative humidity and a very wide temperature range, we are concerned that any imperfections (preexisting or that develop due to the stresses between the coating and the substrate during repeated thermal cycling) in the plating will ultimately allow these effects to cause distortions that will negatively affect the flatness of the mirror surface. Another concern is whether the mirror would be able to be re-coated without having to re-polish or re-figure the mirror. That is, can the final (e.g. aluminum) coating be stripped and re-coated without damage to the nickel underlayer? In light of these considerations, my colleagues and I feel that this type of mirror construction is not likely suitable for our application."
