“…It rises from 10.2 MPa at particle size of 160-180 mesh to 12.4 MPa at particle size of 40 to 60 mesh. These results are in good agreement with the previous data [26][27][28]. This behavior may be due to the cutting of wood fibers during grinding, which affects the strength of wood fibers.…”

“…Zaini et al [28] reported decreasing tensile strength with increasing oil palm wood-flour filler loading from 20 to 50 wt%. However, Bouafif et al [26] concluded that increasing maximum tensile strength increased eastern white cedar wood particle content from 0 to 45 wt%. Table 1 represents the result of flexural modulus and strength measurements of poplar wood-flour=HDPE composites.…”

In this study, the influence of coupling agent concentration (0 and 3 wt%), wood fiber content (50, 60, 70, and 80 wt%), and size (40-60, 80-100, and 160-180 mesh) on the mechanical properties of wood=high-density-polyethylene (HDPE) composites (WPCs) was investigated. WPC samples were prepared with poplar wood-flour, HDPE, and polyethylene maleic anhydride copolymer (MAPE) as coupling agent. It was found that the tensile properties and the flexural properties of the composites were improved by the addition of 3 wt% MAPE, and the improved interfacial adhesion was well confirmed by SEM micrographs. It was also observed that the best mechanical properties of wood= HDPE composites can be reached with larger particle size in the range studied, while too-small particle size was adverse for the mechanical properties of wood=HDPE composites. Moreover, the tensile modulus, tensile strength, and flexural strength of WPCs decreased with the increase in fiber content from 50 to 80 wt%; the flexural modulus of WPCs increased with the increase in fiber content from 50 to 70 wt% and then decreased as the fiber content reached 80 wt%. The variances in property performance are helpful for the end-user to choose an appropriate coupling agent (MAPE) concentration, wood fiber content, and particle size based on performance needs and cost considerations.

The fibers orientation in the polymer matrix is an important factor determining mechanical properties of products made of composites by means of an injection molding process. The fibers arrangement has an effect on shrinkage of the composite and the dimensional accuracy of molded piece. The knowledge of fiber orientation can determine the proper dimensions and design of the molding cavities and then correct some of physical and mechanical properties of the molded piece. The orientation of fillers depends on many factors, among which the important role play processing parameters including the injection speed. The aim of this study was to assess the orientation of the fibers in wood-polymer composite on the selected examples. The knowledge and proper use of micromechanical models allow to evaluate the fibers flow and their orientation in polymer matrix. The research was performed both for numerical simulations and experimental studies for results verification.

“…The fibers have important role in the composite properties; therefore there are comprehensive investigations of different aspects of fibers affects on this category of structures, i.e. fiber characteristics 1 , different behaviors of synthetic fibers 2 and cellulosic fibers 3 contrary to natural fibers 4 . Effect of the fiber content as another important parameter in short-fiber reinforced composites studies should be considered.…”

The Acoustical model of wood-fiber-filled gypsum composites panel is presented. The transmission loss coefficients of the composite structures were calculated by an approximated approach. However, the physical and mechanical properties of board specimens including; water absorption, thickness swelling, bending modulus of elasticity, bending modulus of rupture, internal bond, and compression parallel to the surface obtained experimentally. Finally, the effects of wood fibers to gypsum mixing ratios on physical, mechanical and acoustical properties of composite flat structures were investigated and data analysis was done by use of statistical methods.
