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.

对环境有不利影响的材料的热力学性能

摘要在本研究中，我们使用热重分析和脉冲激发技术评估了基于聚丙烯（PP）、高密度聚乙烯（HDPE）和聚对苯二甲酸乙二醇酯（PET）的材料的热性能和力学性能。结果表明，即使使用熔化的输入材料和~4MPa的压力来生产样品，我们也可以在样品中的砂粒周围发现小空洞。在热稳定性方面，结果表明，在HDPE+PET组合的情况下，应使用更高的温度。此外，研究结果表明，砂可以提高再生材料试样的杨氏模量。
