摘要

建築用布膜耐候性之檢測評估可分實際戶外曝曬試驗和加速老化曝曬試驗。實際戶外曝曬試驗，使布膜拉張狀態下進行曝晒，其曝曬週期為2年、5年、10年之久；加速老化曝曬試驗則是將布膜在適當機台進行照射以達一定累積能量。本研究是藉由3種膜材料進行實際戶外曝曬試驗和加速老化曝曬試驗之照射，然後量測布膜機械性質變化或觀察其外觀變化。

The weatherability evaluations of architectural membranes conduct an investigation into the solar radiation effect of membrane materials by accelerated weathering test and outdoor exposure test. The period of outdoor exposure for membrane under specified load is usually 2, 5, 10 years. It is the accelerated weathering test, which expose membrane to reach accumulated irradiance energy in the adequate apparatus. This study is measurement of the breaking strength and observation of the appearance for three different membranes after outdoor exposure and accelerated weathering exposure.
