In this experimental studies, three types of fabric such as Jute, Okra and Pineapple Leaf Fiber (PALF) were selected and matrix material such as polypropylene (PP) was selected to manufacture composites. Jute/PP, Okra/PP, and PALF/PP based composites were prepared successfully by a conventional compression molding technique. The objective of this study is to compare the mechanical such as tensile strength (TS), tensile modulus (TM), bending strength (BS), bending modulus (BM), elongation at break (Eb%) and interfacial properties of the composites. Jute fiber (hessian cloth)-reinforced polypropylene matrix composites (45wt% fiber) were fabricated by compression molding. TS, TM, BS, BM, and IS of the composites were found to be 45 MPa, 2.2 GPa, 54 MPa, 4.1 GPa, and 16 kJ/m2, respectively. Then Okra and PALF fiber reinforced polypropylene-based composites (45 wt% fiber) were fabricated and the mechanical properties were compared with those of the jute-based composites. The result revealed that mechanical properties of PALF composite higher than jute and Okra fiber reinforced composites. Water absorption and elongation percentage at break showed different scenario and it was noticed from the experimental study that water absorption and elongation at break (%) of jute fabric was higher than other composites. Fracture sides of the composites were studied by scanning electron microscope (SEM), and the results revealed poor fiber-matrix adhesion for jute fiber-based composites compared to that of the other fiber-based composites (OF/PP and PALF/PP).

This work deals with the dielectric properties of silane treated pineapple leaf fiber and kenaf fiber reinforced phenolic hybrid composites. The aim of the present paper is to investigate the effect of silane treatment on the pineapple leaf fiber–kenaf fiber/matrix interfacial adhesion using the dielectric relaxation spectroscopy in the frequency range from 0.1 Hz to 1 MHz and temperature range from 50 to 180℃. Our hybrid composites were fabricated by hand lay-up method at 50% total fiber loading. All the results obtained were discussed in terms of dynamic molecular and interfacial process. Two interfacial polarizations identified as the Maxwell–Wagner–Sillars effect are observed. We note that silane treatment improved the interfacial adhesion between pineapple leaf fiber/kenaf fiber and phenolic resin and it will help to develop high performance kenaf fiber/pineapple leaf fiber reinforced polymer composites for industrial applications. In fact, as known, the silane treatment developed hydrophobic nature in pineapple leaf fiber and kenaf fiber which is very positive for fiber/matrix compatibility.

The present study is focused on investigating the effect of the micro-mechanical properties of the natural fiber- (pineapple leaf fiber) reinforced polymeric composites by the addition of pineapple leaf micro-particulates. For the investigation, a two-step approach has been used. In the first step, finite element method-based analysis has been used to characterize the tensile and shear properties of the pineapple leaf fiber-reinforced polymeric composites (FRP) and pineapple paticulate-reinforced polymeric composites (PRC), and the adopted finite element method-based analysis has been validated through the experimental approach. In the second step, the validated finite element method-based analysis has been used to characterize the micro-mechanical properties of the hybrid fiber-reinforced polymeric composites (HFRP) fabricated using the pineapple leaf micro-particle embedded epoxy as a matrix material and the pineapple leaf fiber has been used as reinforcing material. It has been observed through the analysis that the micro-mechanical properties of HFRP were superior to that of FRP. There has been a 10.16% increment in Young’s modulus in the longitudinal direction and a 26.36% increment in Young’s modulus in the transverse direction for HFRP over FRP. Further, a 9.91% increment for in-plane shear modulus and 26.17% increment in outer-plane shear modulus have been observed for HFRP in comparison to FRP. These results suggest that pineapple leaf particulates are good reinforcing materials to enhance the transverse direction and outer plane micro-mechanical properties of the fiber-reinforced composite.
