Study the Effect of Titanuim Particles Addition on the Some mechanical Properties of Hybrid Composite Materials

Abstract

This research studied the mechanical properties (tensile strength ,impact strength and Brinell hardness) for hybrid material with matrix of unsaturated polyester reinforced by four different weight fraction (5,10,15,20)% of titanium particales, with constant percentage 10% of carbon or glass fiber. Standard samples for tensile, impact and hardness test were prepared. Three samples for each percentage and the average of the three recorded data were taken , the results showed high improvement in the tensile strength from (11.7,22) MPa to (18,29.5) MPa for hybrid polyester reinforced by 10% glass and carbon fiber with 15% weight fraction of titanium particles respectively. Impact test also showed good improvement from (75,160)KJ/m2 to (115,210)KJ/m2 for hybrid polyester with 15% titanium particles. The hardness increased from (98,393)HBN for hybrid polyester with 15% titanium . Generally reinforced by 15% weight fraction for titanium particles improved the mechanical properties more than the rest weight fraction by titanium particles and the same reinforced condition.
