Curing studies of unsaturated polyester resin used in FRP products
Fiber reinforced plastics (FRP) products being strong and light in weight, find extensive applications in automobiles, marine, structural and household components. Unsaturated polyester (UP) resin is a principle binder material used in FRP products. Curing of UP resin is a key for successful FRP processing. Gel time (tgel) and peak exothermic temperature (θpeak) are critical measures of curing ...
متن کاملResin Tearing: a Polyester Gelcoat Surface Defect
Polyester gelcoat has been a useful and popular coating for RP fabrication for over twenty years. The gelcoat has not only been important as a protective coating for the fiberglass laminate in a large variety of construction applications, but in many cases has provided a cosmetically desirable finish that enhances the attractiveness and market value of the RP part. In recent years as the manufa...
متن کاملUnsaturated Polyester Resin for Specialty Applications
Polymers are substances whose molecules consist of a large number of units of a few types: the units themselves, consisting of a number of atoms, are usually referred to as the segments of the polymer. In the polymerization of a mixture of two monomers, the structure of each macromolecule contains units of both monomers. Such a polymer is called copolymer and the process of its synthesis is cal...
متن کاملMechanical Properties of Unsaturated Polyester Resin
Mechanical behaviour of unsaturated polyester resin used for the composite materials has been studied to determine various important parameters, such as tensile and compressive, single edge-notch tensile fracture toughness, flexural properties and fracture energy. Fracture toughness, KIC, and fracture energy, GIC, obtained for the polyester resin lie between the typical values for epoxy resins ...
متن کاملStudies on Digitalis VI
T IS undisputed that the administration of digitalis to patients with many forms of congestive heart failure results in an improvement in both the clinical state and in the abnormal circulatory dynamics that are characteristic of heart failure.'-6 The effects of digitalis in subjects without heart failure are less well defined. Although some glycosides augment the contractile force of nonfailin...
