This study uses a combination of wood flour, obtained from kiwi twigs, together with refined fibers and polypropylene material to make a hybrid composite of polypropylene/wood/fiber. The materials were mixed in a twin-screw extruder, and the samples were made via an injection molding method. The tensile, flexural, and impact strengths, as well as the physical characteristics were measured based on ASTM standards. The results indicated that when the flour dimensions were reduced from 20 mesh to 40 mesh, the tensile and flexural strength, tensile and flexural modulus, and elongation at break were reduced. The notched impact strength, water absorption, and thickness swelling during 2 h and 24 h of immersion in water, and the water absorption and thickness swelling during 2 h immersion in boiling water, increased. In addition, by increasing the amount of refined fiber instead of kiwi wood flour, the tensile and flexural strength, tensile and flexural modulus, elongation at break, and the notched impact strength were increased. The water absorption and thickness swelling during 24 h of immersion in water and the water absorption and thickness swelling during 2 h immersion in boiling water were decreased.

“…Several theories of the dependence of composite properties on filler volume fraction F and geometry have been investigated. 23,[35][36][37] In a simple model Nicolais and Narkis 35 developed a geometric model for the tensile strength s of a composite with uniformly distributed spherical filler particles of equal radius…”

To determine the possibility of using sugarcane bagasse (SCB) waste as reinforcing filler in the thermoplastic polymer matrix, SCB-reinforced polypropylene (PP) composites were prepared. The PP and SCB composites were prepared by the extrusion of PP resin with 5, 10, 15, and 20 wt % of SCB filler in a corotating twin screw extruder. The extruded strands were cut into pellets and injection molded to make test specimens. These specimens were tested for physicomechanical properties such as tensile, flexural, Izod, and Charpy impact strengths, density, water absorption, and thermal characteristics, namely, heat deflection temperature (HDT), melt flow index, and thermogravimetric analysis. It was found that the flexural strength increased from 23.66 to 26.84 MPa, Izod impact strength increased from 10.499 to 13.23 Kg cm/cm, Charpy impact strength increased from 10.096 to 13.98 Kg cm/cm, and HDT increased from 45.5 to 66.58C, with increase in filler loading from 5 to 20% in the PP matrix. However, the tensile strength and elongation decreased from 32.22 to 27.21 MPa and 164.4 to 11.20% respectively.

“…This situation makes wood flour a competitive substitute for the cellulose fibers, especially when extrusion compounding and injection molding are used as processing methods. 6 Chen et al 7,8 prepared a series of maleated polypropylene (MPP) compatibilized polypropylene (PP)/ bamboo fiber composites with higher tensile strength, lower density, and lower cost. The results showed that the tensile strength and the stiffness of bamboo fiberreinforced PP composites were higher than those of the commercial wood pulp composite that was widely used in making office furniture.…”

ABSTRACT:Composites of unplasticized poly(vinyl chloride) (PVC) blended with bamboo flour and pine flour, respectively, were prepared in a batch mixer followed by compression molding. The effects of wood flour fillers on the morphology, static mechanical properties, and thermal properties of the composites were investigated. Compared with neat PVC resin, the introduction of both bamboo flour and pine flour significantly improved the stiffness of the composites, while decreasing the tensile strength to some extent. Tensile tests showed that pine flour-filled composites exhibited better mechanical properties than those filled with bamboo flour with the same particle size at the same loading level. Scanning electron microscopic examination revealed good dispersion and alignment tendency of short pine fiber within the composites at a lower loading level. Moreover, experimental results indicated that both bamboo flour and pine flour additions showed no obviously adverse effect on the thermal stabilities of these composites. Based on the comprehensive properties, these composites meet the need of woodlike material for use as wood structures.
