                 摘要:利用动态接触角考察了双环戊二烯(DCPD)树脂(S-D、3S-D 和 SCB-600)与玻璃纤维(GF)的浸润
                 性,通过 90°拉伸强度和层间剪切强度测试不同 DCPD 树脂与玻璃纤维之间的黏附力,研究了浸润性对树脂与
                 GF 结合性的影响。结果表明,动态接触角为 60.35°±0.3°的 SCB-600 与 GF 具有良好的浸润性,由其制备的 PDCPD
                 基玻璃纤维复合材料〔GF/PDCPD (SCB-600)〕的 90°拉伸强度为(42.3±1.2) MPa,层间剪切强度为(61.3±3.2)
                 MPa,达到环氧基玻璃纤维复合材料〔GF/1564 环氧树脂〕结合性能。当 SCB-600 质量分数为 30%±2%时,
                 GF/PDCPD (SCB-600)具有最优的力学性能,拉伸强度为(1180.1±4.1) MPa,弯曲强度为(1060.4±4.6) MPa,
                                                                              2
                 与 GF/1564 环氧树脂相当,但其悬臂梁缺口冲击强度达到(145.3±4.8) kJ/m ,明显优于 GF/1564 环氧树脂,
                 说明 GF/PDCPD (SCB-600)在抗冲击方面具有广泛的应用前景。

                 Abstract: The impregnation capacity of a series  of  dicyclopentadiene (DCPD) resins (S-D, 3S-D and
                 SCB-600) on  glass  fiber  (GF)  was studied  by  dynamic contact angle analysis. The interfacial adhesion
                 between different DCPD resins and GF was tested by 90° tensile strength and interlaminar shear strength
                 measurements, and the effect of wettability on the bonding property between GF and resin was investigated.
                 The results showed that SCB-600 had the lowest dynamic contact angle of 60.35°±0.3° among the resins
                 tested, which  suggested better impregnation behavior with GF. The PDCPD-based  GF composite [GF/
                 PDCPD (SCB-600)] prepared from SCB-600 had a 90° tensile strength of (42.3±1.2) MPa, interlaminar
                 shear strength of (61.3±3.2) MPa,  which  achieved the  bonding ability of epoxy-based  GF composites
                 GF/1564 epoxy resin. GF/PDCPD (SCB-600) with SCB-600 mass fraction of 30%±2% demonstrated the
                 best mechanical properties, exhibited in the form of the tensile strength and bending strength with a value of
                 (1180.1±4.1) MPa and (1060.4±4.6) MPa respectively, which was equivalent to those of GF/1564 epoxy
                 resin.  However, the cantilever notched impact strength  of  GF/PDCPD (SCB-600) reached (145.3±4.8)
                     2
                 kJ/m , obviously better than that of GF/1564 epoxy resin, suggesting that GF/PDCPD (SCB-600) could
                 have promising application prospects in impact resistance.
