The Solidification temperature range was defined as 110-200℃ by DSC analysis. More accelerant used can increase the casing samples dynamic performance, but more than enough accelerant can induce a severe solidified reaction that result in a smaller polymeric meshwork and reducing the sample's performance. Normally the Accelerant dosage can be 2 portions; The Epoxy resin CFRP has a obvious better performances than the Vinyl-ester Resin CFRP, i.e. had a Bend Strength of 1516MPa, LSS of 85MPa, also Tg raised to 195~C~ When used the end-carboxyl polyether to reinforce the epoxy resin, the casing sample's SS, BS and Crack Elongation all increased geminately. The CFRP performance also increased a little, that is because the performance of the CFRP mainly contributed by the CF. The reinforced resin improved the interface between the CF and resin that contribute to the little increasing.

通过DSC分析确定了该环氧树脂的固化温度范围为110~200℃，促进剂增加会提高浇注体力学性能，但过多的促进剂会使固化反应剧烈，聚合网络减小，使浇注体性能下降，一般用量为2份左右；以环氧树脂为基体的复合材料性能明显比以乙烯基酯树脂的性能提高，弯曲强度达到1516MPa，层间剪切强度达到85MPa，同时Tg也上升到195℃；用端羧基聚醚增韧环氧树脂后，其浇注体的拉伸强度、弯曲强度及断裂伸长都成倍增加，复合材料的性能也有所提高，但提高幅度不大，因为复合材料的力学性能主要由碳纤维承担，树脂增韧后改善了复合材料的界面性能。

The application of accelerator NS instead of NOBS in the tread and carcass ply compounds of bias ply tire was investigated.

研究以促进剂NS替代促进剂NOBS在斜交轮胎胎面胶和帘布胶中的应用效果。

The results showed that the similar curing rate was obtained by using NS in the tread and carcass ply compounds instead of NOBS,but the scorch time reduce somewhat;the physical properties of vulcanizate and the endurance of finished tire changed little;and the pollution of production environment improved significantly and the material cost reduced,thus the better economic and social benefits were obtained.

The experiment results indicated that the cross-linking mechanism of hydrogenated terpinene maleic anhydride with bisphenol A epoxy resin was similar to anhydride curing with epoxy resin in the presence of accelerants. The curing degree was increasing as the curing temperature was arisen and the curing time was delayed, and the gelation time was shortened obviously as the curing temperature was arisen and the dosage of accelerants was increased.

实验结果表明：HTMA与环氧树脂的固化反应过程与促进剂作用下的酸酐固化环氧树脂的交联反应机理一致；固化度随温度升高、时间延长而提高，而凝胶时间随温度升高、促进剂用量的增加明显缩短。

The basic range of FUCHEM VER are unpromoted and required the addition of both accelerators and promoters just like general UPR. The selection criteria of the curing system and amounts depend on the desired gel time, the temperature of both the resin and workshop, the laminate thickness, humidity, impurities and the posting-curing possibilities.
