INFLUENCE OF NANO-ADDITIVES AND RECYCLATE FROM COMPOSITE WASTE ON THE HARDNESS OF POLYESTER-GLASS COMPOSITE

Currently, polyester-glass composites are used in various branch of industry. The structure of the composite and its composition affect the strength properties of the material. To improve the strength parameters of composites, the addition of nanoelements such as aluminum and its oxides is used. The strength properties of composites affect the possibility of their use in various types of structures. The article examines the effect of the content of aluminum additive on the hardness of the composite. An innovative aspect of the research is the use of composites containing recycled polyester-glass waste. The samples were made of composites produced by hand lamination technology. A composite material with a recyclate waste content of 10% and granulation.
