Abstract

The use of metallic materials as structural and machine components has limitations such as high weight, susceptibility to corrosion, and relatively high production costs. Therefore, the development of mineral composite materials based on silica sand has become a potential alternative. This study aims to analyze the effect of variations in the mixture of silica sand, carbon nanotubes (CNTs), silicon dioxide (SiO₂), and phenolic resin compositions, as well as thermoforming casting process parameters, on the mechanical properties and microstructural characteristics of mineral composites. The research method employed a Taguchi L9 (3⁴) experimental design with variations in aggregate–filler ratio, molding pressure, thermoforming temperature, and CNT percentage. Mechanical testing was conducted through Vickers microhardness tests and bending tests, while microstructural analysis was performed using Scanning Electron Microscopy (SEM). Data were analyzed using the signal-to-noise ratio (S/N) and Analysis of Variance (ANOVA). The research results show that variations in composition and process parameters significantly affect the mechanical properties of the composite. The highest hardness value of 335 HV was obtained at the aggregate–filler ratio combination of 75:25, molding pressure of 200 kg/cm², temperature of 170°C, and 1.5% CNTs. SEM analysis showed a homogeneous structure and good matrix–filler bonding. The dominant factor affecting the mechanical properties is the aggregate–filler ratio.
