Abstarct: Abstract Nowdays, in all industries, researchers are looking for the use of materials that cause the least damage to the environment and can be recycled. Therefore, the use of natural fibers with mineral baxses and green composites has helped a lot in the composite materials manufacturing industry. Due to its many advantages, such as high strength, high thermal resistance, and having a mineral baxse, basalt fibers are a suitable alternative to synthetic fibers such as carbon and glass. Combining materials in macroscopic and microscopic dimensions increases the strength of composite materials and creates hybrid composites. On the other hand, the use of composites along with mextal materials such as aluminum or titanium alloys can improve the weight of structures and their strength, as well as prevent damage such as corrosion. Carbon nanotubes are considered as one of the ideal reinforcements for increasing the reinforcement of polymeric materials due to their suitable mechanical and physical properties. By adding a small amount of this nano material, the properties of the composite improve significantly. In this research, the effect of adding 0.25, 0.5, and 1 percent by weight of carbon nanotubes to the composite of basalt, epoxy, and aluminum mextal fibers was done using the manual laxyering method, and three-point bending and buckling test samples were extracted. The results of the three-point bending test indicated that the sample containing 1 percent by weight of carbon nanotubes was optimal for this test and significantly increased the bending strength, bending modulus, and energy absorbed at the moment of failure. In the buckling test, the addition of carbon نانولوله کربنی برای این آزمون دارای بالاترین استحکام خمشی بوده و استحکام خمشی، مدول خمشی و انرژی جذب‌شده در لحظه شکست را به میزان چشمگیری افزایش داده است. در آزمون کمانش نیز افزودن نانولوله‌های کربنی به ماده زمینه باعث بهبود خواص ماده شد. مشخص شد افزودن 5/0 درصد از نانولوله‌های کربنی به ماده زمینه مناسب ترین میزان برای افزایش استحکام کمانش ماده است. همچنین نتایج تجربی با نرم‌افزار المان محدود اعتبار سنجی شد. کلمات کلیدی: کامپوزیت سبز، کامپوزیت هیبریدی، بازالت، نانولوله کربنی، خمش، کمانش، محیط‌زیست Abstract Nowdays, in all industries, researchers are looking for the use of materials that cause the least damage to the environment and can be recycled.

In the buckling test, the addition of carbon nanotubes to the baxse material improved the properties of the material. It was found that adding 0.5% of carbon nanotubes to the baxse material is the most optimal amount to increase the buckling strength of the material. Also, the experimental results were validated with finite element software.
