Mechanical 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 ...

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...

Effect of water absorption on the mechanical properties of hemp fibre reinforced unsaturated polyester composites

Hemp fibre reinforced unsaturated polyester composites (HFRUPE) were subjected to water immersion tests in order to study the effects of water absorption on the mechanical properties. HFRUPE composites specimens containing 0, 0.10, 0.15, 0.21 and 0.26 fibre volume fraction were prepared. Water absorption tests were conducted by immersing specimens in a de-ionised water bath at 25 C and 100 C fo...

Polyester Nanocomposite fibers with Antibacterial Properties

Antibacterial nanocomposite polyester (PET) fibres were melt spun by adding nano ZnO loaded Linear Low Density Polyethylene (LLDPE) master batch (MB) to the PET chips. The influence of content of nano ZnO on the antibacterial properties, crystallization behaviour and mechanical properties was studied. It was found that PET composite fibres having 1 % nano ZnO showed the optimum antibacterial ac...
