STUDY THE EFFECT OF TIO2/ZNO NANOPARTICLES ON MECHANICAL AND THERMAL PROPERTIES OF EPOXY NANO COMPOSITES

Abstract

In this paper, the additive effect of (titanium oxide TiO2 and zinc oxide Zn O) nanoparticles to the epoxy resin as a matrix  have been studied, In addition to the manufacturing of hybrid compounds from the same nanoparticles  which are (TiO2 / Zn O) depending on the epoxy also as a base material. The hand lay- up method is using to manufacturing the composites  from the epoxy resin and nanoparticles with different weight ratios (0.2,0.4,0.6,0.8,1) wt%, Impact Strength test and Compression Strength test and the thermal have been done of all prepared composites. FE(SEM) was  used to study the composition of the nanoparticles used in this research, which are titanium oxide and zinc oxideThe results of the tests showed that adding the aforementioned ceramic powders improved the mechanical properties of the composite materials the nano composite (EP+ZnO) had highest Impact Strength (0.8 wt%)  and highest Compression Strength , the hybrid (EP+TiO₂ /ZnO ) compound had the highest Impact Strength on (0.8wt %) and highest Compression Strength on the ratio(1wt%) followed by (EP+TiO₂) composite had highest Impact Strength on the ratio (0.6wt%) and highest Compression Strength on (1wt%). The results showed that the differential scanning calorimetric (DSC) test has showed that the glass transition temperature of all epoxy composites  increases at all weight ratios of reinforcement materials compared with pure epoxy and the high test value of glass transition temperature (T_g) is to the composite composite (EP+TiO₂ ) that equal (67^oC ) in the ratio (0.6wt%)   , as well as, the crystalline melting temperature of all epoxy composite has showed atypical behavior compared with pure epoxy by increasing the  weight  concentration.And the results of FE(SEM) showed that Morphology of Zinc Oxide and Titanium Oxide Nanoparticles nearly spherical .
