Rubber Ferrite Composites

The incorporation of various types of ferrites in rubber matrixes leads to the development of rubber ferrite composites (RFC). These RFC have a large number of applications as flexible magnets, high-tech sensors, for telecommunication and radiowave absorbers. Both natural and synthetic rubber has the potential of being value added by the incorporation of ferrites. Applications like microwave absorbers warrant that these composites have an appropriate dielectric strength with the required magnetic property. This can be achieved by synthesizing composites based on natural rubber and ferrites. In this paper we report the synthesis of RFC containing barium ferrite according to a specific recipe and its evaluation of dielectric and mechanical properties.

Dielectric And Mechanical Properties

Cables are an integral part of the power transmission and distribution network. As the voltage level increases, amount of insulation used in the cable increases. Therefore a need arises for a material with better insulation characteristics to be used in cables. The dielectric strength of cable insulation depends on many factors such as the existence of filler material in the insulation. In this work, laboratory studies on a new filler material for cable insulation have been conducted. The influence of Silicon dioxide (SiO2) filler on the dielectric and mechanical properties of polyvinyl chloride (PVC) cable were analyzed. Comparison is made between the result of measurement and the actual value of the pure specimen. From the results, it is shown that the filler material has improved the dielectric and mechanical properties of the cable insulation.

Polyester Composite

This research has been done by reinforcing the matrix (unsaturated polyester) resin with natural material (date palm fiber (DPF)). The fibers were exposure to alkali treatment before reinforcement. The samples have been prepared by using hand lay-up technique with fiber volume fraction of (10%, 20% and 30%). After preparation of the mechanical and physical properties have been studied such as, compression, flexural, impact strength, thermal conductivity, Dielectric constant and dielectric strength. The polyester composite reinforced with date palm fiber at volume fraction (10% and 20%) has good mechanical properties rather than pure unsaturated polyester material, while the composite reinforced with 30% Vf present poor mechanical properties. Thermal conductivity results indicated insulator composite behavior. The effect of present fiber polar group induces of decreasing in dielectric strength, and increasing dielectric constant. The reinforcement composite 20% Vf showed the best results in mechanical, thermal and electrical properties.
