Additive manufacturing (AM) technologies have been successfully applied in various applications. Fused deposition modeling (FDM), one of popular AM techniques, is most widely used method for manufacturing of plastic materials. Due to the poor strength properties of pure plastic materials, there is a critical need to improve mechanical properties for FDMfabricated pure plastic parts. One of the ...

Surface roughness and wettability of flat-pressed wood plastic composites (WPCs) incorporated with various fire retardants (FRs) (5, 10, or 15% by weight (wt)) at 50 wt-% content of the wood flour (WF) were investigated. The most common FRs, zinc borate (ZB), magnesium hydroxide (MH), and ammonium polyphosphate (APP), were used in the experiments. The WPC panels were made from dry-blended wood ...

In recent years, extensive studies have been carried out on natural fiber reinforced thermoplastics due to their low cost, high specific properties, simple fabrication methods, biodegradable nature and diverse applications touching all commercial sectors. The challenge is to make composites with properties that are not overly compromised by the use of low technology. In this work, we review the...

Previous studies have shown favourable properties for papaya bast fibres, with a Young's modulus of up to 10 GPa and a tensile strength of up to 100 MPa. Because the fibres remain as residues on papaya plantations across the tropics in large quantities, their use in the making of green composites would seem to be worthy of consideration. This study aims to show that such composites can have ver...

Švec I., Hrušková M. (2015): Characteristics of wheat, barley and hemp model composites. Czech J. Food Sci., 33: 66–71. Barley is known as health-benefit raw material, mainly due to beta-glucan. To explore the nutritional benefit of barley and hemp plants, wheat-barley flour premixes were prepared (70 : 30 and 50 :0 50 w/w, respectively). Hemp flour of wholemeal and fine type was added to each ...

Interfacial compatibility plays a key role in the performances of natural fiber-reinforced composites. The measures commonly used to improve the interfacial compatibility focus more on the addition of various compatibilizers than on the structural modification of the natural fiber. In this paper, an attempt was made to enlarge the interfacial interaction areas of the recycled polyethylene (rPE)...

With its market demand expansion and increased application areas, products of wood-plastic composite (WPC) have been developing growing rapidly in many countries over the last decades. This paper attempts to investigate effect wood species that are waste from furniture industries on performance composites (WPCs). The samples were prepared by varying flour at 30wt% mixed with 70wt% HDPE (High De...

mechanical properties of wood/plastic composites manufactured by polyethylene and polypropylene blends (pp/hdpe) were studied. the sebs (styrene-ethylene butylene-styrene) and epdm (ethylene-propylene diene monomer) were used as compatibilizers to improve the compatibility and miscibility of the interface between hdpe and pp phases. the sawdust and polymers were compounded using an internal mix...

Bagasse is a waste generated in abundance from the sugarcane industry. This investigation was planned to convert bagasse into useful composite. For this purpose obtained sugar cane juice producer. In study, extraction of fibers done manually and they were treated with sodium hydroxide. The had higher tensile properties as compared untreated ones, so alkali used reinforcement for making composit...

In this study, mechanical and biodegradability properties of wood plastic composite were investigated. Beech (fagus orientalis) flour 40 wt% was used as a reinforcing base material, maleic anhydride coupling agents nano clay to improve the added. The polymer studied polyhydroxybutyrate (PHB) other high-density polyethylene (HDPE) .Three groups composites produced, in two each polymers alone thi...
