Abstract
In this paper, a polymer-based composite material was prepared by hand Lay-up method consisting of epoxy resin as a base material reinforced by magnesium oxide powder once and silicon dioxide powder again and with different weight ratios (3, 6, 9 and 12) wt %. The three-point bending test was performed in normal conditions and after immersion in sulfuric acid. The results showed that the bending value decreased with the increase of the weighted ratio of the reinforcement material (MgO, SiO2). The Bending of samples reinforced by SiO2 was found to be less than the bending of samples reinforced by particles (MgO). For example, the bending of the SiO2 sample (0.32 mm) at the weighted ratio (3%) and for the MgO (0.18mm) sample at the weight ratio were the same weighted load (100 g). It was found that the bending values of all samples exceeded the value after immersion in sulfuric acid. For example, the percentage of weight (6%) at the load level (500 g) was changed from 1.16 mm in normal conditions to 1.48mm for the same weight ratio after immersion. In sulfuric acid diluted with 0.3N for 10 days at the same applied load.
Highlights
A complex known as a solid system is produced by mixing two or more different materials in form or composition
The elasticity coefficient of the composite material was higher than the base material and showed that the hardness of the composite material was much higher than the hardness of the base material, this improvement in properties increases with the increase of the silica weight fracture [3]
The SiO2 deflection was less than the deflection of magnesium oxide powder (MgO) samples at the same weight ratios
Summary
A complex known as a solid system is produced by mixing two or more different materials in form or composition. - Composite material made of epoxy resins supported by micro particle of SiO2 and MgO at different weight ratios (3, 6, 9 and 12) wt%.
