Abstract:The present article evaluates the effect of variation of WF on the tensile strength, modulus, and elongation at break. The pin-bearing properties usually correlate well with tensile properties. Tensile strength and pin-bearing strength decrease but tensile modulus increases on addition of WF. The tensile strength, pin-bearing strength, and mode of pin-bearing failure also depends on the void content. Increase in void content has a detrimental effect on all the mechanical properties. Wide variation is observed … Show more

This paper deals with the influence of inorganic electrical insulator waste filler on the properties of glass fiber reinforced epoxy composite. The electrical insulator waste fillers were uniformly mixed in the resin through ultrasonication technique. Composites were made up with different percentages of filler (0, 5, 10, 20 wt%) and 20 wt% glass fiber using the hand lay-up method. Physical, mechanical, water absorption, thermal, and dynamic mechanical properties were studied. The experimental results indicate an increase in water absorption and density of composites with increased electrical insulator waste filler in the polymer matrix. Furthermore, the filler addition reduces the tensile strength and increases the flexural strength to 402 MPa at 20% addition. The thermogravimetric analysis reveals that the incorporation of electrical insulator waste filler increases the thermal stability considerably. Dynamic property reveals the damping property of the materials, in which the incorporation of 20% filler leads to higher storage modulus. Particle dispersion and failure mode were analyzed using scanning electron microscope. This work highlights the possibility for reprocessing electrical insulator waste as low-cost reinforcement in polymer composites.

“…Therefore, when it is made into filament and stored, it absorbs moisture in the atmosphere. When the filament is melted at approximately 200 ℃, due to the rapid increase in temperature, the moisture in the WF vaporizes and is discharged out of the WF, pushing out the polymer matrix in the melt flow state and creating a spatial volume (Joshi and Marathe 2010). The voids generated by this activity are relatively small in size and irregular.…”
Fused deposition modeling (FDM) 3D printing technology is the most common system for polymer additive manufacturing (AM). Recent studies have been conducted to expand both the range of materials that can be used for FDM and their applications. As a filler, wood flour was incorporated into poly lactic acid (PLA) polymer to develop a biocomposite material. Composite filaments were manufactured with various wood flour contents and then successfully used for 3D printing. Morphological, mechanical, and biodegradation properties of FDM 3D-printed PLA composites were investigated. To mitigate brittleness, 5 phr of maleic anhydride grafted ethylene propylene diene monomer (MA-EPDM) was added to the composite blends, and microstructural properties of the composites were examined by scanning electron microscopy (SEM). Mechanical strength tests demonstrated that elasticity was imparted to the composites. Additionally, test results showed that the addition of wood flour to the PLA matrix promoted pore generation and further influenced the mechanical and biodegradation properties of the 3D-printed composites. An excellent effect of wood flour on the biodegradation properties of FDM 3D-printed PLA composites was observed.
“…Study of Joshi and Marathe 110 on mechanical properties of highly filled PVC/WF composites indicated a reduction in tensile strength due to poor interfacial adhesion between the hydrophobic PVC and hydrophilic WF; pin-bearing and impact strengths because in absence of a coupling agent, stress transfer between filler and matrix does not occur. On the other hand, thermogravimetric analysis results showed insignificant effect of WF content on the thermal stability of the composites.…”

Materials from renewable resources – also called biomaterials or ‘green’ materials – are presently gaining in importance worldwide. In these times of continuous increases in the price of crude oil and discussion of carbon dioxide (CO2) emissions, conventional plastics have reached a price level and a questionable image which promotes the search of alternatives. Natural fibers are a renewable natural resource and are biodegradable, which is an important characteristic for components that must be disposed of at the end of their useful life. They are recyclable and can be easily converted into thermal energy through combustion without leaving residue. In this study, we will discuss the natural fiber reinforced polyvinyl chloride composites, reinforcing effect, plasticization effect along with modification by coupling agents, properties, and applications based on composite materials. Also, the polyvinyl chloride-based composite materials with specific emphasis on effect of coupling agent, foamed polyvinyl chloride composites, and the effect of natural fiber reinforcement on its material properties will be reviewed. One of the best alternatives is natural fiber reinforced plastics composites. These are composites that are typically filled or reinforced with plant fibers, as well as plastics such as polyvinyl chloride or recently, even bioplastics.
