Experimental Investigation of Tensile Strength and Thermal Conductivity of Nanoparticle Reinforcement Composite Materials

Abstract

In this study, different nanoparticles were added to composite materials made of polymers, which are frequently used in industrial, at different concentration ratios. By adding nanoparticles to the matrices, it is aimed to analyze the thermal conductivity and tensile strength of the material. These resins, which were mixed homogeneously with a magnetic stirrer, were applied to the carbon fiber fabric and placed in the mold in layers by hand laying method. The samples in the mold were kept at room temperature (25 °C) for 48 hours and their production has completed. The prepared samples were mixed for 20 minutes by adding 100% resin + carbon fiber, 2% and 5% TiO₂, 2% and 5% SiO₂, 2% TiO₂ + SiO₂ and 5% TiO₂ + SiO₂ hybrid nanoparticles by mass concentration. Tensile strength and thermal conductivity values of the completed samples were measured. Among the samples obtained, it was determined that the composite material without nanoparticles had a maximum tensile strength value of 774,435 MPa. For the thermal conductivity value, it was determined that the thermal conductivity value of the reinforced sample with 5% TiO₂ nanoparticles increased by 15.74% compared to the composite material without nanoparticles.
