“…[30] The excess of absorbed water observed in the iPP/WF composites can be attributed to the presence of microcavities at the interface which can easily allow water absorption. [15,31,32] However, the addition of a compatibilizer, i.e., EBAGMA or MAPP, into the polymer matrix decreases the water absorption by almost 50 wt.-%. This result is interpreted as an improvement of the interfacial adhesion between the wood flour and the iPP matrix by encapsulation of the filler with the compatibilizer, reducing the water sensitivity of the composite.…”

“…[7][8][9][10][11][12][13][14] As a matter of fact, most data reported in the literature is devoted to maleated poly(propylene) (MAPP) and its role as a compatibilizer in iPP/WF composites due to its effectiveness in improving both the tensile and flexural strengths of the materials. [15] In contrast, no work has been carried out on the performance of ethylene butyl acrylate glycidyl methacrylate (EBAGMA) terpolymer as an interfacial agent for woodplastic composites. Although effective interfacial activity of the EBAGMA terpolymer was found in LDPE/PET blends, where the two polymer components are known to be immiscible resulting in poor mechanical properties, [16] literature data is rather scarce around the application of EBAGMA terpolymer for other multiphase systems.…”

Summary: This paper presents the results of an experimental investigation concerning the use of an ethylene butyl acrylate and glycidyl methacrylate (EBAGMA) terpolymer as an interfacial agent for isotactic poly(propylene)/wood flour (iPP/WF) composites at various filler ratios (10, 20 and 30 wt.‐%). The effects of the EBAGMA terpolymer on the morphology, tensile properties, impact strength and water uptake of the iPP/WF composites were studied and the results were compared with those obtained with maleated poly(propylene) (MAPP) used as a compatibilizer. Initially, the mixing process was performed in a calendaring unit at 170 °C for pre‐homogenization of the filler in the matrix. Composites made out of these combinations were then ground and injected into a standard mold at 180 °C in the absence and the presence of compatibilizer. The results indicated that both EBAGMA terpolymer and MAPP improved the interactions between iPP and WF, and induced a better dispersion of wood particles in the polymer matrix, as revealed by scanning electron microscopy (SEM). Furthermore, tensile properties and impact strength were also increased. Another important effect was on the water absorption property, which was significantly lower for the samples with EBAGMA and MAPP. However, EBAGMA terpolymer produced better enhancement of the properties of the iPP/WF composites compared to the compatibilized samples with MAPP.

“…They also reported that the moisture sorption and strength reduction are further suppressed by using maleic anhydride polypropylene (MAPP) as a coupling agent in both types of composite system. 18,19 In this study, mechanical tests of WRPC specimens with and without chopped GF were characterized. The impact fractured surface of glass fiberreinforced wood plastic hybrid composites (GWPCs) was observed through scanning electron microscope (SEM).…”

“…interfacial modification. Existing literatures have reported a number of works 8,9 attempting to improve the structural or mechanical properties, and environmental behavior of the WRPCs products in various means, such as use of synthetic fiber, metal inserts, and glass fiber (GF). Among them, incorporation of GF reinforcements into polymer matrix is the most effective method to improve the mechanical properties of plastics.…”

To fully utilize the resource in the municipal solid waste (MSW) and improve the strength and toughness of wood plastic composites, glass fiber (GF)-reinforced wood plastic hybrid composites (GWPCs) were prepared through compounding of recycled high-density polyethylene (HDPE) from MSW, waste wood fibers, and chopped GF. Mechanical tests of GWPCs specimens with varying amounts of GF content were carried out and the impact fractured surface of GWPCs was observed through scanning electron microscope (SEM). The tensile strength of GWPCs and the efficiency coefficient values were predicted by Kelly-Tyson method. The results indicated that the tensile strength and impact strength of GWPCs could be improved simultaneously by adding type L chopped GF (L-GF), and would be dropped down when type S chopped GF (S-GF) was included. The tensile strength of GWPCs was well accordant with the experimental result. The efficiency coefficient values of S-GF and L-GF are À0.19 and 0.63, respectively. Inspection of SEM micrographs indicated that L-GF had achieved full adhesion with the plastic matrix through addition of maleic anhydride-g-polyethylene. The main fracture modes of GWPCs included pullout of GF, broken of matrix, and interfacial debonding. Because of the synergistic effects between hybrid components in GF/wood fiber/ HDPE hybrid system, a special 3D network microstructure was formed, which was the main contribution to the significant improvement in the tensile strength and impact strength of L-GF-reinforced hybrid composites.

“…Many researchers' interest has been attracted by natural biomaterials in recent years because of their unique properties [1][2][3][4][5][6]. Through observing some soil animals such as dung beetle, pangolin, etc., it is found that there are, respectively, convex, reticulate and striate shapes on animals' body surfaces and the wear-resistances of animals' body surfaces are better when they are crawling [7,8].…”
