The research on the advanced technique for FRP boat processing and restoration which used the new curing system

对于FRP工艺，在对树脂的粘度和凝胶时间的估计和调整错误时，粘度升高，在浸渍完成之前就开始固化，出现缺陷。因此，作者研究了在树脂中加入不饱和聚酯树脂固化剂的微胶囊的分布技术，在浸渍完成玻璃钢成型（如树脂注射成型工艺）后破坏胶囊，并开始固化的技术。采用浸没硬化法制备了以甲基纤维素为原料的胶囊壳，并对其在空气中的稳定性、容器寿命和性能进行了研究。并将胶囊型固化剂应用于二次粘接、模型船体加工，验证了其有效性。

As for FRP processing, the viscosity rises, the curing begins before the impregnation completes and the flaw occurs, when making a mistake in the estimate and the adjustment of the viscosity and gel time of the resin. Therefore, the authors examined about the technique to distribute the microcapsule which includes an unsaturated-polyester-resin curing agent in the resin, to destroy the capsule after impregnation completion of FRP forming such as the resin infusion molding process, and to begin curing. The capsule shell made with the methyl cellulose was prepared by the submerged hardening method, and investigated the stability in the air, pot life and the characteristics of FRP. Moreover, the capsular curing agent was applied to the secondary adhesion, model hull processing and the validity was confirmed.
