Unsaturated 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 کاملMicrofibrillated Lignocellulose Enables the Suspension-Polymerisation of Unsaturated Polyester Resin for Novel Composite Applications
A new route towards embedding fibrillated cellulose in a non-polar thermoset matrix without any use of organic solvent or chemical surface modification is presented. It is shown that microfibrillated lignocellulose made from cellulose with high residual lignin content is capable of stabilising an emulsion of unsaturated polyester resin in water due to its amphiphilic surface-chemical character....
متن کاملCuring 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 کاملEvaluation of Drilling Performance of Unsaturated Polyester Resin
Unsaturated polyester resin (UPR) has the resistance against boiled water, acid and alkali, and hence, is widely used in corrosive environment and elsewhere, although fracture strength of polymeric materials is generally low relative to metals and ceramics. Despite the fact that polymer components are mostly produced near-net-shape, machining, particularly drilling, is often required to prepare...
