Properties of unsaturated polyester-coconut shell composite with titanium oxide addition

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 ...

Water Absorption and Compressive Properties of Coconut Shell Particle Reinforced-Epoxy Composite

The Aim of present investigations is to evaluate the physical property-water absorptions and mechanical property-compressive properties. Coconut particle reinforced composites were fabricated by reinforcing shell particle (size between 200-800μm) by wt% of 20, 25, 30 & 35 into epoxy matrix. Composites plates were made by casting in open mould. That is possible with very low cost and easy way. E...

Electrically and Electrochemically Active Composite Based on Polyester/Reduced Graphene Oxide/Polypyrrole with Remarkable Washing Durability

Mechanical Properties of Green Coconut Fiber Reinforced Hdpe Polymer Composite

During the last few years, natural fibers have received much more attention than ever before from the research community all over the world. These natural fibers offer a number of advantages over traditional synthetic fibers. The present study aims to determine the mechanical properties namely, Tensile strength (TS), Flexural strength (FS), and Impact strength (IS) of green coconut fiber reinfo...

Microfibrillated 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....
