Polyester/paper composites: study of manufacturing techniques for product development

ABSTRACT Composite materials using vegetal fibers and industrial waste are being applied in different areas and structures, requiring, more and more, researches that highlight their characteristics. In this context, the study of manufacturing techniques becomes increasingly necessary in order to use the appropriate tools and obtain the best conditions of the materials. Thus, this article demonstrates the behavior of the materials, which used the polyester resin with ground paper residue to generate the two composites studied in this paper, Polyester/smaller paper (PO/ PME) and Polyester/large paper (PO/PMA). These two materials were molded by hot compression and subjected to manufacturing processes. Joinery equipment were chosen for the experimentation of cutting, drilling, screw insertion and sanding to analyze the performance of these composite materials. As a general result, it can be observed that the composites maintained their physical integrity, because the particles of the load remained well anchored in the matrix in the two composite materials tested, giving the finish an aspect without damages, cracks or imperfections after the operations. Therefore, it is concluded that the materials created can be submitted to the manufacturing techniques evaluated in this article, reinforcing previous studies that suggest its use in the development of products such as furniture, table tops, decorative objects and others. Thus, this study contributes to Designer has knowledge of the potential of the material and make the best use of it.摘要：采用植物纤维与工业废弃物制备的复合材料，正被应用于诸多不同领域与结构中，愈发需要相关研究以阐明其性能特性。在此背景下，为选用适配的加工工具并获取材料最佳性能，制造工艺的研究愈发关键。为此，本文针对以聚酯树脂搭配磨碎纸渣制备的两种复合材料开展研究，分别为聚酯/细纸渣复合材料（Polyester/smaller paper，PO/PME）与聚酯/粗纸渣复合材料（Polyester/large paper，PO/PMA）。上述两种材料均通过热压成型工艺制备，并经受后续加工制程测试。本实验选用木工加工设备，开展切割、钻孔、螺钉安装与砂光作业，以分析这两种复合材料的加工性能。综合实验结果表明，两种受试复合材料均保持了物理结构完整性：填料颗粒均在基体中实现了良好锚固，经上述加工操作后，成品表面无破损、裂纹或瑕疵，外观状态优异。综上，本研究证实所制备的复合材料可适配本文所评估的各类加工工艺，佐证了此前相关研究提出的该材料可用于开发家具、桌面、装饰摆件等产品的结论。本研究可为设计师提供该材料的性能潜力相关认知，助力其实现材料的最优应用。
