碩士 === 國立臺南大學 === 綠色能源學科技學系碩士在職專班 === 105 === Unsaturated polyester and vinyl ester resin is a good chemical resistance of the modified thermosetting resin.And the free radical polymerization, the end of the olefinic bond with each other so that the vinyl ester cross-linking density is high, the strength also will increase.But also because of the higher density of cross-linking, making the cross-linked vinyl resin more brittle Therefore, this study mainly to vinyl ester as the base for the addition of toughened material to achieve performance, toughness enhanced effect. The thesis describes a technique for vinyl ester resin synthesis containing CTBN. The toughening resin Sample38 is developed successfully through selection of CTBN source, adjust of synthetic procedure, optimization of raw material ratio and application of thixotropic agent, and have highly toughness, impact resistance, elongation and lap shear strength after radical initiator is used. Compare a series of tests with contender, resin Sample38 is better. (Sample38:163.2 Kgf/cm2，Sample 60:44.8 Kgf/cm2). The aircraft body is used of adhesive, the structural weight is reduced by 15%, so the application of this resin significantly reduces the use of cladding materials and manpower to reduce the waste of resources.
