玻璃纖維基材塗佈聚四氟乙烯耐候性及其物理性質之評估

工業用的複合材料基本性能要求為重量、密度、斷裂強力、撕裂強力、耐磨損性、耐候性等，本論文是以平紋組織的玻璃纖維基材塗佈聚四氟乙烯而成的複合材料經由耐候性、機械性...等之試驗評估，探討國內自製品使用之可行性。膜材耐候性之試驗評估可分室外曝曬試驗和加速老化曝曬試驗。室外曝曬試驗，使膜材拉張狀態下進行一定週期的曝曬；加速老化曝曬則是將膜材在適當條件下進行照射達一定的累積能量。本研究是藉由複合材料進行加速老化曝曬試驗之照射，然後評估膜材機械性質變化或觀察其外觀變化。

The basic properties of the complex material requirements for the weight, density, breaking strength, tear strength, abrasion resistance, Weatherability etc., the study is a plain weave glass fiber coated with a composite made of polytetrafluoroethylene material through weathering resistance, mechanical testing ... etc. assesses the feasibility of composite materials used. The weatherability evaluations of 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. It is the accelerated weathering test, which expose membrane to reach accumulated irradiance energy in a design condition. This study is evalmating the breaking strength and observing the appearance complex materials accelerated weathering exposure processes
