| Weathering characteristics of potential solar reflector materials: a survey of the literature | |
| Hampton, H.L.; Lind, M.A. | |
| 英文摘要 | A review of the available literature on the weatherability/durability of materials with possible applications in solar reflectors is summarized. A number of techniques used to weather solar materials are reviewed. These include both natural and simulated weathering. Little correlation has been shown to exist between natural and accelerated weathering, and much work needs to be done before results of accelerated aging tests can be used with confidence to predict material lifetimes under outdoors exposure conditions. Some of the techniques used to measure or monitor material degradation are discussed. Emphasis in the literature has been placed chiefly on mechanical properties or appearance oriented measurements. The need is apparent for more detailed optical measurements of materials properties that are directly useful in engineering design. Although a great deal of literature is available on the materials described in the survey, there is very little solid data on the properties important for solar applications. A brief discussion of some of the applicable data on polymeric materials and glass is presented and referenced. The importance of cleaning solar materials is emphasized and some attempts at modeling degradation are discussed. |
