摘要： Grafted triglycerides comprising an acrylated triglyceride grafted with a fatty acid residue containing 4 to 28 carbon atoms. Also described are methods for making a grafted triglyceride and for curing a material selected from vinyl esters and unsaturated polyesters and mixtures thereof and optionally a reactive diluent. The method includes the steps of mixing a grafted triglyceride of the present invention with a material selected from vinyl esters, unsaturated polyesters and mixtures thereof to form a mixture, and curing the mixture to form a cured resin system. A cured resin system comprising a cured product obtained by the foregoing method and composites containing the cured product and a filler or reinforcing material are also disclosed. This method also includes use of the grafted triglycerides to make toughened resin and composite systems with reduced hazardous air pollutants without significantly reducing the glass transition temperature and significantly increasing the viscosity.

摘要： An article and a process are provided for reducing the shear stress on an interface of a structural member in intimate contact with a compressive load. The article is in the form of a wedge that is forcibly placed against the sidewall of one end or both ends of the structural member. The wedge may take the form of a ring that can be placed on the inside or outside surface of a hollow cylindrical structural member. The process of forcibly placing a wedge against the sidewall at one or both ends of the structural member produces a transverse compressive stress upon the sidewall. The transverse compressive stress upon the sidewall attenuates the tendency of said sidewall to deflect when the structural member is subjected to a compressive load. A reduction in the deflection of the sidewall reduces the shear stress generated proximal to the interface of the structural member in intimate contact with a compressive load and increases the structural member load bearing capacity.
摘要翻译：提供了一种用于减小与压缩载荷紧密接触的结构构件的界面上的剪切应力的制品和方法。该制品是楔形的形式，其被强制地放置在结构构件的一端或两端的侧壁上。楔形件可以呈环形的形式，该环可以放置在中空圆柱形结构件的内表面或外表面上。在结构构件的一端或两端强制将楔形物放置在侧壁上的过程在侧壁上产生横向压应力。当结构构件受到压缩载荷时，侧壁上的横向压缩应力衰减了所述侧壁偏转的趋势。侧壁偏转的减小减小了与压缩载荷紧密接触的结构构件的界面附近产生的剪切应力，并增加了结构构件承载能力。
