Etaati, Amir and Pather, Selvan and Cardona, Francisco and Wang, Hao (2016) Injection molded noil hemp fiber composites: interfacial shear strength, fiber strength, and aspect ratio. Polymer Composites, 37 (1). pp. 213-220. ISSN 0272-8397

Abstract

Noil hemp fiber-reinforced polypropylene composites were fabricated using intermixer and injection molding machines. X-ray microtomography and Weibull statistical methods were employed to characterize the aspect ratio distributions of noil hemp fibers in the polypropylene matrices. The influence of fiber content (0–40 wt%) and compatibilizer addition (5 wt%) on IFSS (interfacial shear strengths) was evaluated by means of the modified Bowyer and Bader model. The evaluated IFSSs decreased from 9.7 to 7.2 MPa as the fiber content increased from 10 to 40 wt%. Also, the outcomes indicated increases to IFSSs for the maleic anhydride grafted polypropylene (MAPP)-coupled composites than uncoupled ones. They were used to predict theoretical tensile strength of the composites. A good agreement has been found between the theoretical and the experimental tensile strengths of composites indicating that the developed model has excellent capability to predict the tensile strength of noil hemp fiber reinforced polypropylene composites. Ultimately, the influences of interfacial shear strength; fiber strength and fiber aspect ratio were investigated using the developed model to predict composite tensile strengths.
