Creep-compliance master curve for MBMDPE 4. Planned FY 2005 Activities Based on very positive results using a UV screen adhesively bonded to polycarbonate sheet, industry has made a pilot version of a thermally bonded UV screen/polycarbonate construction. This material has degraded significantly faster than the adhesively bonded structure. During FY 2005, we will investigate this effect and propose and test solutions to the problem. We will also interact with industry to prepare and test samples of UV screens that incorporate newly developed UV absorbers that have increased photopermanence. Several industry partners are considering unglazed collectors that use polymer absorbers. The UV resistance of candidate absorber materials will be explored by performing dynamic mechanical analysis (DMA) as a function of UV exposure. A considerable advantage of DMA is that it is non-destructive, thereby greatly reducing the number of samples required. Samples will be exposed at NREL’s UV-concentrator facility and in accelerated exposure chambers and outdoors. The most significant activities planned for FY 2005 include: • The reason(s) why thermally bonded UV screens provide less protection for polycarbonate glazings than adhesively D(t) (1/MPa)PDF Image | FY 2004 ANNUAL REPORT DOE Solar
