Abstract
Abstract In this study, we evaluate the thermal and mechanical properties of materials based on polypropylene (PP), high-density polyethylene (HDPE), and polyethylene terephthalate (PET) using the thermogravimetric analysis and impulse excitation technique. The results show that even if the melted input material together with the pressure of ~4 MPa was used to produce the samples, we can find small cavities around the sand grains in the samples. In case of thermal stability, the results show that in case of HDPE + PET combination, higher temperature should be used. Besides that, the results show that sand should increase the Young’s modulus of the samples from recycled materials.
期刊介绍：
Acta Technologica Agriculturae is an international scientific double-blind peer reviewed journal focused on agricultural engineering. The journal is multidisciplinary and publishes original research and review papers in engineering, agricultural and biological sciences, and materials science. Aims and Scope Areas of interest include but are not limited to: agricultural and biosystems engineering; machines and mechanization of agricultural production; information and electrical technologies; agro-product and food processing engineering; physical, chemical and biological changes in the soil caused by tillage and field traffic, soil working machinery and terramechanics; renewable energy sources and bioenergy; rural buildings; related issues from applied physics and chemistry, ecology, economy and energy.
