本論文將探討兩大部分，分別為聚酯織物補強聚丙烯複合材料與新式全高分子複合材料製程。
聚酯織物補強聚丙烯複合材料(PET/PP複合材料)將著重在聚丙烯具有密度低(質量輕)、加工溫度低、取得容易，而聚對苯二甲酸乙二酯的優點則為高拉伸強度並容易染色，藉由結合這兩種高分子材料的優點，製成一質量輕，並具有高強度的PET/PP複合材料。
複合材料製程中材料選用與使用材料的型態皆為重要的課題，本實驗使用長PET纖維織物進行補強以乘載荷重，能有效提升整體機械性質。為因應碳纖維複合材料的潮流，更選用色母染色的黑色無加撚PET紗進行織造，獲得2/2斜紋12k仿碳纖外觀織物。
然而，這兩種材料，具有熱相容性上的問題，此界面不良的狀況，將影響基材與補強材受力時，無法將力有效傳導，導致基材與補強材脫層並破壞。本研究將使用馬來酸酐接枝聚丙烯進行基材改質。所得最佳拉伸應力達到156.8 MPa，楊氏模數達到4.2 GPa。
而新式複合材料製程將由芯鞘型複合紗概念進行延伸，優點為適用於各式高分子。本研究將低熔點聚丙烯(基材)包裹於高強力聚丙烯紗(補強材)，形成一srPP扁平紗並克服扁平紗紡織時翻紗問題，成功製備srPP織物，以其熔點差異，形成一加工視窗，熱壓製成srPP複合材料。拉伸應力達到112.1 MPa，楊氏模數2.1 GPa。

In this study, surface treatment of PET/PP composites and new composites manufacturing process are discussed.
Polypropylene has the advantages of light weight, low Tm and easy to get. And polyester has the advantages of high tensile properties and easy to dye. PET/PP composites combined these advantages to make it a light weight and high tensile properties composites.
It’s an important issue to select materials for composites. In order to sustain load well, PET fabric is used. Because of it, the mechanical properties of PET/PP composites increased. The untwisted, solution dyed black PET yarn are used to make this PET/PP composites have carbon composites' appearance. High transparent PP is melt blended with PP-g-MA and PET fabric is pretreated with primer to solve the interfacial problems. PP-g-MA content and primer usage are discussed. The best tensile strength and young’s modulus of PET/PP composites are 156.8 MPa and 4.2 GPa.
The new composites manufacturing process is extended by core and sheath method. High tenacity PP yarn and low melting temperature PP and are used as core and sheath to make a flat srPP yarn. By the difference of melting temperature, a processing window is formed. After woven, srPP composite is made by hot compaction. The tensile strength and young’s modulus are 112.1 MPa and 2.1 GPa.
