    Flexural and quasi-static compressive behavior of injection-molded walnut shell (WS)/HDPE composites
    (Zibeline International Publishing Sdn. Bhd., 2019) Malagi, S.; Anawal, R.; Gorabal, S.V.; Doddamani, M.
    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. © 2019 Zibeline International Publishing Sdn. Bhd. All rights reserved.

    Tensile characteristics of HDPE/Walnut shell composites
    (2019) Malagi, S.; Anawal, R.; Gorabal, S.V.; Doddamani, M.
    Present work deals with tensile characterization of walnut shell (WS) powder (20, 40 and 60 volume %) reinforced High Density Polyethylene (HDPE) thermoplastic composites synthesized using injection molding. Composite density and tensile modulus increases with increasing WS content wherein tensile strength of composite samples is lower as compared to neat HDPE. Specific modulus and strength show increasing and decreasing trend with higher WS loading respectively. � 2019 IOP Publishing Ltd. All rights reserved.
