ABS塑膠具有優異物理特性，常用於資訊業、家電用品、事務機器及汽車零件，因溫度效應造成機械性質的變化導致產品的損壞有密切關係。 本文研究以國喬ABS-D1000A試片在不同溫度作用下，佐以拉伸及尺寸變化之線性膨脹係數等實驗分析材料性質與溫度的關係，在70°~-20°間，每隔10°溫度變化觀察ABS塑膠，在定溫回歸室溫及定變溫下之材料性質的變化，並進一步將其結果應用於改善電視面框的結構設計，以減少面框因冷熱衝擊循環溫度變化所造成的損壞。 由實驗中歸納出材料特性隨溫度變化的相互關係，利用結構改良手法減少溫度效應所造成損害並加以驗證，確保產品品質。實驗數據及範例提供其它產品設計參考並可進一步配合軟體分析建立一個標準資料庫。 The material of ABS contains outstanding physical properties. It is quite popular in the information industry, appliance equipment, mutiprinter and vehicle parts. The damage of ABS products caused by the mechanical properties changed is relevant closely to the temperature effect. The paper analyzes the relationship between material properties and the temperature, with the ABS-D1000A specimen of Grand Pacific Petrochemical Corporation, under the experiment of Linear-Coefficient of expansion of tension and dimensions change. Between 70℃ and -20℃, inspecting the variation of ABS material in every 10℃. The experiment controls the temperature from specific to room and varies it in every certain degree. In order to reduce the damage of the television frame which was caused by the cycle thermal shock, the test result was finally implemented in the structure design. The experiment generalizes the relationship between temperature and material properties. The purpose is to minimize the damage from temperature effect by improving the structure design and validate the production quality. The experiment data and examples provide a reference for other products development. Moreover, through the analysis of CAE (Computer-aided engineering) it can be further established as a standard database. Key work: ABS plastic, Cycle thermal shock, Material tension experiment.
