Abstract

The present study focuses on flexural and quasi-static compression behavior of high-density polyethylene (HDPE)/walnut shell (WS) composites. Flexural and quasi-static compression specimens by 20, 40 and 60 wt. % of WS are synthesized by polymer injection (PI) molding. The flexural modulus and strength are observed to increase with increase in the wt.% of WS. Compared to pure HDPE, the flexural modulus and strength increased in the range of 205-403% and 49-58% respectively. Further quasi-static compression tests are carried at 0.001, 0.01, 0.1 s-1 strain rates. Compressive modulus of HDPE/WS specimens is lower as compared to pure HDPE samples for all the strain rates. Compressive yield strength of HDPE/WS specimens shows increasing trend with increase in the strain rates. Scanning electron microscopy (SEM) is employed to study the fractography of the samples.

注射成型核桃壳/高密度聚乙烯复合材料的弯曲和准静态压缩性能

本文主要研究了高密度聚乙烯(HDPE)/核桃壳(WS)复合材料的弯曲和准静态压缩性能。通过聚合物注射(PI)成型，合成了20%、40%和60% wt. % WS的弯曲和准静态压缩试样。试件的抗弯模量和强度随wt %的增加而增加。与纯HDPE相比，其抗弯模量和强度分别提高了205 ~ 403%和49 ~ 58%。进一步在0.001、0.01、0.1 s-1应变速率下进行准静态压缩试验。在所有应变速率下，HDPE/WS试样的压缩模量都低于纯HDPE试样。随着应变速率的增加，HDPE/WS试样的抗压屈服强度呈增加趋势。采用扫描电子显微镜(SEM)对试样的断口形貌进行了研究。
