    摘要: 本研究計畫旨在探討玻璃纖維強化杜塞型聚胺基甲酸酯改質酚醛樹脂拉擠成型複合材料加工製程之研究。利用杜塞型聚胺基甲酸酯改質酚醛樹脂之預聚合物為基材來進行拉擠成型加工,藉樹脂變數之調整來控制預聚合物之分子量與黏度,在將杜塞型聚胺基甲酸酯改質酚醛樹脂之預聚合物經特別設計之拉擠成型設備,及利用玻璃纖維強化杜塞型聚胺基甲酸酯改質酚醛樹脂之基材為系統,藉助高分子反應動力學及複合材料測試方法,配合各種儀器及電子計算機模擬,多方面探討以尋求最適當之樹脂配方與加工條件,以製作優異之高分子複合材料。本研究計畫之主要目標可細分如下: 1.探討杜塞型聚胺基甲酸酯改質酚醛樹脂之預聚合物加工之可行性參數:樹脂黏度與溫度之關係,樹脂操作時間,樹脂反應性,樹脂與纖維形態學之探討。 2.探討樹脂配方對拉擠成型加工條件之影響。 3.尋求在拉擠成型過程中最適當之加工參數,包括拉擠速度、模具溫度、後硬化溫度與時間、填充劑種類和含量等。 4.探討杜塞型聚胺基甲酸酯含量對拉擠成型複合材料性質之影響。 5.製造高性質(耐燃、耐溫、耐腐蝕、耐摩耗、高強度等)之複合材料,並測試其各項物理性質、機械性質、熱性質與耐燃性質。
    This project investigates a proprietary process developed to manufacture pultruded glass fiber reinforced blocked polyurethane modified phenolic resin (phenolic/blocked PU) composites. To utilize blocked polyurethane modified phenolic prepolymer as matrices for pultrusion, and controlling the molecular weight, viscosity of blocked polyurethane modified phenolic prepolymer and through the self-designed pultrusion facility. The blocked polyurethane modified phenolic prepolymer were used directly and polymerized in the pultrusion die. It provides a new concept for in-situ pultrusion. To study the process feasibility of utilizing blocked polyurethane modified phenolic resin as polymeric matrix to fabricate pultruded glass fiber composites, and to manufacture the high performance composites. This research project will include the following subjects: 1. To study the process feasibility of blocked polyurethane modified phenolic prepolymer: the relation between viscosity and temperature of resin, pot life of resin, reactivity of resin, and morphology between resin and fiber. 2. To study the effects of resin formulation on pultruded processing condition. 3. To seek the optimum processing parameters for pultrusion, including pulling rate, die temperature, postcure temperature and time, and filler type and content etc. 4. To investigate the effects of blocked PU content on composite properties. 5. To manufacture the high performance (flame resistance, heat resistance, corrosion resistance, abrasion resistance, high strength etc.) composites by pultrusion, and to test the physical, mechanical, thermal and flame properties of composites.
