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.
