为提高热塑性树脂聚丙烯(PP)与玻璃纤维(GF)之间的界面相容性和粘结强度，提出了一种对GF三步浸渍的方法，将GF逐步用(3-氨丙基)三乙氧基硅烷(γ–APS)，1，6-己二异氰酸酯(HDI)及苄胺或十八胺处理，从而在GF表面接枝上长的分子链。利用接触角测定仪、衰减全反射傅立叶变换红外光谱(ATR–FTIR)仪和X射线光电子能谱(XPS)仪等手段，对改性后的GF表面进行了表征，证明了接枝反应的成功进行。将不同方法改性的GF与PP制备成单向PP／GF复合材料，对其进行了拉伸性能测试。结果表明，随着GF表面接枝的碳链增长，复合材料的拉伸强度逐渐增大。

In order to improve the interface compatibility and adhesion strength between thermoplastics resin poly-propylene(PP) and glass fiber(GF),a three-step GF surface modification method was developed. With this method,GF was treated by 3-aminopropyltriethoxysilane(γ–APS),1,6-diisocyanatohexane(HDI) and benzylamine or octadecylamine stepwise,so that organic chain structure was successfully grafted onto GF surface. The surface modified GF was characterized by contact angle measurement, ATR–FTIR and XPS. Results show that the surface modification method is efficient and successful. The effect of the grafting on the tensile strength of GF/PP composites was investigated by tensile test. It is found that the tensile strength of the composites is significantly increased with the lengthening of grafted chain. Thus,modified GF by this method can considerably enhance the tensile strength of PP/GF composites.
