Green composites are a special class of composites in which at least one of the components is obtained from natural resources. They are an alternative to traditional composites because of their useful properties such as biodegradability, low cost, easy processability, sound insulation and recycling. Green composites, which emerge as environmentally friendly polymeric composite materials, offer techno-economic advantages in commercial and engineering applications and are one of the widely dealt subjects due to the very high demand from the global market. The aim of this study is to investigate the effect of chestnut wood flour size on the mechanical properties of chestnut wood flour filled vinylester composites. With this aim, composite specimens were produced by using vinylester polymer as matrix material and chestnut wood flour in three different sizes (0-150-micron, 150-315-micron, 315-400-micron) as natural filler. In each size combination, 4 different matrix/filler ratio (5%, 10%, 15%, 20% by weight) were adopted. These mixtures were then poured into Teflon molds to produce test specimens. Izod impact, three-point bending, hardness, tensile tests were performed on composite specimens. In addition, morphological investigations were performed on the fractured surfaces of the specimens by using scanning electron microscopy (SEM). It is concluded that composites with small size chestnut wood flour as the filler have superior properties for composite applications.

栗木粉粒度对栗木粉填充乙烯基酯复合材料力学性能的影响

绿色复合材料是一类特殊的复合材料,其中至少一种成分是从自然资源中获得的。它们是传统复合材料的替代品,因为它们具有诸如生物降解性,低成本,易于加工,隔音和回收利用等有用特性。绿色复合材料是一种环保型聚合物复合材料,在商业和工程应用中具有技术经济优势,由于全球市场的需求量很大,因此成为广泛涉及的主题之一。这项研究的目的是研究栗木粉的尺寸对栗木粉填充的乙烯基酯复合材料的机械性能的影响。为此,通过使用乙烯基酯聚合物作为基质材料,并使用三种不同尺寸(0-150微米,150-315微米,315-400微米)的栗木粉作为天然填料,制成复合样品。在每种尺寸组合中,采用了4种不同的基质/填料比率(5%,10%,15%,20%重量)。然后将这些混合物倒入特氟龙模具中以生产测试样品。在复合材料样品上进行了悬臂梁式冲击,三点弯曲,硬度和拉伸试验。另外,通过使用扫描电子显微镜(SEM)对样品的断裂表面进行了形态学研究。结论是,以小栗木粉作为填料的复合材料在复合材料应用中具有优异的性能。采用了4种不同的基质/填料比率(按重量计5%,10%,15%,20%)。然后将这些混合物倒入特氟隆模具中以生产测试样品。在复合材料样品上进行了悬臂梁式冲击,三点弯曲,硬度和拉伸试验。另外,通过使用扫描电子显微镜(SEM)对样品的断裂表面进行了形态学研究。结论是,以小栗木粉作为填料的复合材料在复合材料应用中具有优异的性能。采用了4种不同的基质/填料比率(按重量计5%,10%,15%,20%)。然后将这些混合物倒入特氟龙模具中以生产测试样品。在复合材料样品上进行了悬臂梁式冲击,三点弯曲,硬度和拉伸试验。另外,通过使用扫描电子显微镜(SEM)对样品的断裂表面进行了形态学研究。结论是,以小板栗木粉作为填料的复合材料在复合材料应用中具有优异的性能。使用扫描电子显微镜(SEM)对样品的断裂表面进行了形态学研究。结论是,以小栗木粉作为填料的复合材料在复合材料应用中具有优异的性能。使用扫描电子显微镜(SEM)对样品的断裂表面进行了形态学研究。结论是,以小栗木粉作为填料的复合材料在复合材料应用中具有优异的性能。
