Purpose: The paper presents a simply method of preparation of polymer matrix nanocomposite reinforced with carbon nanotubes and their influence on the mechanical properties. Design/methodology/approach: A series of polymer matrix nanocomposite materials at filler weight fractions 5%, 10%, 15%, 20%, 30% and 40% both in the absence and in the presence of multiwalled carbon nanotubes (MWCNTs) at a 0.1% wt. were prepared. The specimens were tested at 3 point-bending and tension using an universal testing machine. Findings: The paper presents the way of preparation of nanocomposite materials. The components were carefully measured and mixed in vacuum. The carbon nanotubes were homogenized using ultrasonicator. After that the mixture was injected into the moulds and heated in the temperature of 50°C by 24h.Practical implications: Polymer composites reinforced with carbon nanotubes are considered to be an important group of materials for many engineering applications. MWCNTs (used as reinforcement in nanocomposites) have greater mechanical strength and endurance and a greater modulus of elasticity comparing to carbon fibers. Polymer nanocomposites reinforced with carbon nanotubes have been used at the production of chemical sensors, materials using emission field phenomenon, media converters, electrical appliances, supercapacitors. Originality/value: Paper presents new polymer matric nanocomposites with high Young’s modulus. Polymer nanocomposites reinforced with carbon nanotubes are characterized by dimensional stability, high stiffness, toughness, heat resistance, low combustibility, reduction of the transmission of liquids and gases, the lower density, low thermal expansion coefficient, and increased electrical conductivity.
