Investigation of effects of added hemp fiber particles on tensile behavior of acrylonitrile-butadiene-styrene

Abstract

This study aimed at investigating the effects of hemp fiber particles with an approximate size of 500 μm added at three various weight ratios including 1wt%, 5wt%, and 10wt%, on the tensile behavior of Acrylonitrile-Butadiene-Styrene (ABS) at low strain rates varying from 1 × 10−4 to 6.25 ×10−2 s−1. Regardless of a strain rate, tensile test results revealed that increasing particle content leads to a significant improvement in the tensile modulus of neat ABS but a decrease in its post-yield strength. Additionally, it was found that the ductility of neat ABS decreases with both increasing particle content and strain rate. The results also showed that ABS experiences a less intrinsic yield drop after post-yield as both particle content and strain rate enhance. Additionally, it was concluded that increasing the weight ratio of particles in ABS leads to higher resistance to plastic localized deformation. Moreover, it was found that an improvement in the weight ratio of particles makes the post-yield strength of ABS more susceptible to strain rate but leads its tensile modulus to be less sensitive to strain rate. The tensile test results were found to be consistent with both X-ray diffraction (XRD) and Fourier Transform Infrared (FT-IR) Spectroscopy results.
