“…One of the most important parameters controlling the mechanical properties of short fibers composite is the fiber length or more precisely its aspect ratio (length/width). A high aspect ratio is very important in fiber reinforced composites, as it indicates potential strength properties 24. Stark and Rowlands3 reported that aspect ratio, rather than particle size, has the greatest effect on strength and stiffness.…”

In this study, to understand how cellulosic materials characteristics influence the mechanical properties of polyvinyl chloride (PVC) composites, we first studied the effect of different types (wood flour and pulp fiber) and contents on selected mechanical properties of uncompatibilized wood plastic composites. We then compared the properties of hybrid composites to those of composites reinforced with wood flour or fiber, individually. PVC as polymer matrix and cellulosic materials were compounded by twin-screw extrusion and test specimens were prepared by injection molding. All tested properties vary significantly with filler form or content. With the addition of wood flour, the tensile strength moderately increases, but with the addition of hybrid filler and pulp fiber, it increases significantly. Notched impact strength increased with increasing particle size. Pulp fiber resulted in higher strength at the 40 wt % level compared with the strength properties of wood flour composites. The higher aspect ratio of the fiber had significant effect on the mechanical properties. Increasing filler load improves the strength of the composite up to a load of 40 wt %, further increase in the filler loading (>40 wt %) results in a decrease in properties, due to the to filler agglomerates. Incorporation of 25% weight fraction of wood pulp fiber in hybrid composites gave the highest values of composite properties. The mechanical properties of hybrid composites are found to be much higher than that composites filled with wood flour. Finally, results showed that the hybrid composites had the maximum improvement in selected mechanical properties.

“…The optimum fiber parameters and their influence on the mechanical properties for Sansevieria cylindrica composites were studied and the results confirmed that the fiber content in weight percentage is playing major role than the fiber length on the mechanical properties of Sansevieria cylindrica composites . The potential waste of agricultural residues such as sunflower stalk, corn stalk and bagasse fibers were used as reinforcement in thermoplastics composites in the past . The study of tensile properties on unidirectional and randomly oriented short fibre lengths from agricultural based plant stem of Zea mays fibre/epoxy composites (ZMFE) has confirmed the usage of Zea mays as reinforcement in polymer matrix composites .…”

Summary: This research work is focused on utilizing waste agricultural residues as reinforcement in polymer composites. Natural cellulose fibers from corn involucre petals were used as reinforcement materials in order to improve the mechanical properties of the polyester composites. Corn involucre petals fibers are the newly identified fiber which are extracted from the corn plants (Zea Mays subsp) using simple manual extraction. The extracted fiber were reinforced in polyester matrix with five level of fiber loading ranging from 10% to 70% and five levels of fiber length ranging from 10 to 50 mm. Hand layup process was used for composite fabrication and the mechanical properties of the fabricated composites were determined experimentally as per ASTM standards and Scanning Electron Microscopy was used for fractography study. The Corn involucre petal fibers reinforced polyester composites exhibited promising mechanical properties which suits their use for commercial and engineering applications.
