Abstract:
This paper focuses on the effect of granite-micro-filler on static mechanical properties, damping behavior, and physical characteristics of silk-sisal hybrid composite. The composites structures are fabricated by using three layers of plain weaves mat with varying weight percentages (2, 4, and 6 wt%) of granite-micro-filler by hand layer process. The effect of granite-micro-filler on silk-sisal is analyzed and results are compared with pure silk-sisal (without granite-Micro-filler) hybrid composite. The results infer that; the tensile strength and flexural strength value of the developed silk-sisal hybrid composites are increased with the increase in wt% of granite-micro-filler content than pure silk-sisal, approximately 5% and 9% improved value in order by adding 6 wt% granite-micro-filler on silk-sisal. The tensile and flexural fracture morphology analysis indicated that composed plain weave of silk-sisal fiber mat with two (longitudinal and transverse) directions possesses higher mechanical properties and also observed that, granite-micro-filler dispersed on silk-sisal fiber mat and resin with closely packed. The improved damping factor is obtained by adding 6 wt% of granite-micro-filler content, which is approximately 75.8% higher than pure silk-sisal. The physical properties of silk-sisal hybrid composite have also been analyzed and well discussed in this paper.
摘要:
本文重点研究了花岗岩微填料对静态力学性能的影响,阻尼行为,蚕丝-剑麻杂化复合材料的物理特性。复合材料结构是通过手动层工艺使用三层平织垫制成的,这些平织垫具有不同重量百分比(2、4和6wt%)的花岗岩微填料。分析了花岗岩-微填料对丝绸-剑麻的影响,并将结果与纯丝绸-剑麻(不含花岗岩-微填料)混合复合材料进行了比较。结果推断;开发的丝-剑麻混合复合材料的拉伸强度和弯曲强度值随着花岗岩-微填料含量的增加而增加,通过在丝剑麻上添加6wt%的花岗岩微填料,约5%和9%的值提高了。拉伸和弯曲断裂形态分析表明,具有两个(纵向和横向)方向的蚕丝-剑麻纤维毡的组合平织具有较高的机械性能,并且还观察到,花岗岩微填料分散在丝绸-剑麻纤维垫和树脂紧密堆积。通过添加6wt%的花岗岩微填料含量来获得改进的阻尼因子,比纯丝剑麻高出约75.8%。本文还对蚕丝-剑麻杂化复合材料的物理性能进行了分析和讨论。
