摘要

本研究目的在探討各種塑膠材料於不同溫度條件下對楊氏係數變化之影響。塑膠材料分別為ABS、ABS+20%GF、PC+20%GF、NY66+20%GF、HIPS、POM等，溫度條件則分別為室溫(25°C)、40°C、55°C、及70°C等。另外針對不同的加熱時間與持溫時間參數作實驗，以比較時間參數對楊氏係數變化之影響。實驗結果顯示，楊氏係數會隨溫度的增加而下降，其中以PC+20%玻璃纖維受溫度上升的影響最小，而HIPS最容易隨溫度上升有明顯下降的趨勢。對於不同的溫度範圍，則以從55°C上升至70°C時，楊氏係數下降的比例最大。結果也顯示加熱時間愈長，塑膠材料的楊氏係數愈低。

This thesis is to study the Young’s modulus of plastic materials under different temperature conditions. The testing plastics are ABS, ABS+20%GF, PC+20%GF, NY66+20%GF, HIPS, and POM. Testing temperature are room temperature (25°C), 40°C, 55°C, and 70°C, etc. We also examine the Young’s modulus of plastics during the different heating time and isothermal time. Results show the Young’s modulus decrease with the temperature increase. However, PC+20%GF has the less influence and HIPS has dropped obviously with the temperature increase. About the different temperature range, the Young’s modulus decreases fast when the temperature of 55°C rises to 70°C. Results also show the longer heating time increases , the lower Young’s modulus of plastic materials decreases.
