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。

Based on these, an improving μ-synthesis is presented, with which the high-purity distillation is designed well. 2. The robust performance problem of MIMO plant is explained with the plant direction angle, which shows that the robust performance varies with different input uncertainties and the μ-synthesis should be applied correctly according to the uncertainty structure. 3. Condition number and bandwidth are the important items for robust performance design in MIMO system. The H〓 two-block problems can not deal with the robust performance design of MIMO system because of the condition number cancellation. A general μ-synthesis procedure for MIMO system with uncertainties is presented. 4. For the SISO system, the object function in robust performance is amplified by at most 〓 than that of H〓 two-block problems in value: So the robust performance of SISO system can be done with the H〓 two-block problems to avoid the complicated μ-synthesis procedure. 5. All the conclusions and methods presented in this paper are demonstrated by some typical design examples.
