“…[7][8][9][10][11][12][13][14][15][16][17][18][19] Many previous studies have shown that the tribological properties of these composite products could be improved by the incorporation of reinforcing agents, including organic and inorganic materials; the reinforcing mechanisms involve the types and contents of the reinforcing agents in the polymer matrices, interfacial bonding, additive distribution, chemical treatments, as well as wear mechanisms. 1,[7][8][9][10][11][12][13][14][15][18][19][20][21][22][23][24][25][26][27] Several studies have attempted to utilize natural fillers as tribologically reinforcing agents in WPC products. Work by Syed and Syed 3 studied the use of spent turmeric as reinforcing filler for load-bearing and tribological applications of polypropylene (PP) composites.…”

Uses of natural wood/PVC composite products are increasing in various fields of construction and in building materials applications. This present work aimed to develop wood/PVC hybrid composite materials by incorporating synthetic fibers, namely E-glass, S-glass, and carbon fibers. Three different wood flours were also considered, including Xylia kerrii Craib & Hutch, Hevea brasiliensis, and Mangifera indica Linn. The mechanical, morphological, and wear properties were of interest. The results suggested that the addition of synthetic fibers significantly improved the flexural properties of wood/PVC composites, but only slightly affected their specific wear rate values, this effect being most pronounced with the incorporation of carbon fiber and when tested at longer sliding distance. The influence of different wood types showed no definite trend on the specific wear rates of the wood/PVC hybrid composites. Among different counterface materials used, a sandpaper counterface resulted in the highest specific wear rate, which involved a two-body abrasion mechanism. The results of this work indicated that S-glass fiber and XK wood were most suitable for co-reinforcing the wood/PVC composites in terms of wear-resistant applications.

A novel two-step combined treatment of poplar wood was developed to improve its dimensional stability. Maleic anhydride (MAN) was first employed to swell and bond to the wood cell wall, and then mixed monomers of glycidyl methacrylate/methyl methacrylate (GMA/MMA) were grafted to the cell wall through the chemical reaction with MAN within the wood cell lumen. The results of scanning electron microscopy and energy dispersive X-ray apparatus (SEM-EDX) and Fourier transform infrared spectroscopy (FTIR) analyses indicate that MAN penetrated and chemically bonded to the cell wall causing 9% volume swelling, and the copolymer from GMA/MMA monomers was grafted onto the wood cell wall, resulting in the improved interfacial compatibility between the polymer and wood matrix. The dimensional stability of poplar wood modified by the combined two-step treatment was remarkably improved compared with that of untreated poplar wood. The combination treatment of wood employed in this study proved to be more effective for improving the dimensional stability than treatment with PEG-1000 aqueous solution with 30% concentration.

A composite material consisting of woody skeleton and polymerized methacrylate has been developed and characterized. This paper presents an experimental program and the results concerning mechanical properties and strength of wood modified with polymerized methacrylate. In the article, there are examples of structural elements made of natural wood. Wood is a composite consisting of the layers of soft and hard wood. Wood is a composite and porous material. The porosity, which is a serious defect of wood, may be simultaneously its advantage. Wood saturation with different impregnates to minimize its disadvantages. If the wood pores will fill the monomer there is obtained the wood polymer composite. This composite is classified as of fiber composites. Such composite is effectively protected against degradation; it is durable in use, and show an improvement in mechanical properties. Design constructions of surface modified wood require the determination of fundamental material constants. Therefore, for the determination of these parameters is very important obtaining the appropriate research material. The surface impregnation of wood allows obtaining strength characteristics in a function of polymer content. This allows to model it's, and then design and perform specific ship structures. In the wood, there are three directions in relation to the annual rings. Wood properties, especially mechanical properties, are different in the selected directions. For the computation takes the orthogonal anisotropy in which there are three mutually orthogonal planes of symmetry, for which there is symmetry properties of the wood.
