本研究使用三種不同主劑與硬化劑重量混合比例之環氧樹脂(主劑：硬化劑=1：1、2：1 和3：1)，探討在不同曝露環境條件下，對環氧樹脂工程性質與修補成效之影響。
研究結果顯示：(1)在一般環境下，7天齡期後，三種環氧樹脂各項工程性質發展均趨於穩定，其中重量混合比2：1之環氧樹脂抗壓強度、劈裂強度與超音波波速皆為最高者，14天齡期達到84.36 MPa、21.22 MPa與2408 m/s，高於其他兩種重量混合比1.24~1.80倍、1.42~1.58倍與1.06~1.09倍。 (2)經溫濕度循環變化環境曝露後，三種環氧樹脂之各項工程性質均呈現衰減狀態，以重量混合比1：1最為明顯，其抗壓強度、抗彎強度與劈裂強度與一般環境比較，減達值達50.34~66.73 %。 (3)在酸鹼環境下，重量混合比1：1之環氧樹脂各工程性質均衰減，與一般環境比較之下，抗壓強度、抗彎強度與劈裂強度明顯衰減12.16 %、27.91 %與22.81 %；重量混合比3：1之環氧樹脂除熱傳導係數外，其抗壓強度、抗彎強度與劈裂強度經酸鹼環境曝露後平均增加1.21~1.45倍。 (4)重量混合比2：1之環氧樹脂修補成效最佳，在一般環境曝露下圍束強度為49.08 MPa與剪力強度為5.81 MPa；重量混合比3：1環氧樹脂在溫濕循環變化環境下之圍束強度與剪力強度衰減最多，分別比一般環境衰減9.76 %與58.28 %，顯示其修補成效容易受到溫濕度之影響。 (5)依田口實驗設計法探討環氧樹脂高溫性質，以S/N因子反應表及反應圖得到A因子(重量混合比例)為所探討的工程性質中影響程度最大者，並由變異數分析中得到其貢獻度在76.12~98.23 %之間，皆為三因子中最高者，顯示重量混合比例有顯著之影響性。

This study investigated the effects of different exposure conditions on the engineering properties and retrofitting performance of epoxy resin made of three different mix proportions of main agent and curing agent by weight (main agent: curing agent = 1:1, 2:1 and 3:1).
Research results show that: (1) Under the general environment, the development of each engineering property of epoxy resin tends to be stable after seven days. At age of 14 days, the epoxy resin with 2:1 mixing ratio by weight has the highest compressive strength, splitting tensile strength and ultrasonic pulse velocity of 84.36 MPa, 21.22 MPa and 2408 m/s, which are higher than those of the other two by 1.24 to 1.80, 1.42 to 1.58 and 1.06~1.09 times, respectively. (2) After exposure to the cyclic environmental changes of temperature and humidity, each engineering property of three epoxy resin becomes decaying, in which, especially, the epoxy resin with mixing ratio of 1:1 is the most significant one. Comparison with those under the general environment attenuation, its compressive, flexural and splitting tensile strengths are reduced by 50.34~66.73%. (3) Under the acid and alkaline environment, each engineering property of the 1:1 epoxy resin becomes decaying. Compared with those under general environment, its compressive, flexural and splitting tensile strengths are reduced by 12.16%, 22.81% and 27.91%, respectively. Except for thermal conductivity, the compressive, flexural and splitting tensile strengths of 3:1 epoxy resin are increased by 1.21~1.45 times to those under general environment. (4) Under the general environment, the retrofitting performance of 2:1 epoxy resin is the best with the compressive strength of 49.08 MPa and shear strength of 5.81 MPa. The compressive and shear strengths of 3:1 epoxy resin show the worst decaying by 9.76 and 58.28%, respectively, comparing with those under the general environment, indicating the retrofitting performance is easily affected by cyclic effects of temperature and humidity. (5) The analysis on the effects of high temperature on the engineering properties of epoxy resin with the Taguchi experimental design method shows that the factor A (mixing ratio by weight) is the most significant factor based on the figures of S/N (signal to noise) ratio and the contribution is between 76.12~98.23% by ANOVA results. Both result show that mixing ratio by weight is the most significant factor on the variations of engineering properties under different environment.
