The research aimed to evaluate the effects of different contents of jupati particles on the properties of composites with a matrix of recycled low-density polyethylene (LDPE). The composites were produced with 0%, 5%, 10% and 15% of jupati particles inserted in the LDPE matrix, and the moisture, bulk density, water absorption, flammability and mechanical resistance were determined. The inclusion of the lignocellulosic material caused an increase in the density, indicating absence of pores, and in the other properties of the composites, except the modulus of rupture. These results were related to its chemical characteristics and the low interaction with the matrix, which can be verified in the scanning electron microscopy images. The work results are interesting and propitiate the development of further questions related to the production parameters, different particle sizes and use of compatibilizing agents to verify the possible effects on the composites.

该研究旨在评估不同含量的 jupati 颗粒对再生低密度聚乙烯 (LDPE) 基体复合材料性能的影响。在 LDPE 基质中插入 0%、5%、10% 和 15% 的 jupati 颗粒生产复合材料，并测定了水分、体积密度、吸水率、可燃性和机械阻力。木质纤维素材料的加入导致密度增加，表明没有孔隙，以及复合材料的其他性能，但断裂模量除外。这些结果与其化学特性和与基质的低相互作用有关，这可以在扫描电子显微镜图像中得到验证。
