Influence of nanoclay and coupling agent on the physical and mechanical properties of polypropylene/bagasse nanocomposite

Abstract

In this work, the effects of nanoclay (1-4 wt %) and coupling agent (2 and 4 wt %) loading on the physical and mechanical properties of nanocomposites are investigated. Composites based on polypropylene (PP), bagasse flour, and nanoclay (montmorillonite type) was made by melt compounding and then compression molding. When 1-3 wt % nanoclay was added, the tensile properties increased significantly, but then decreased slightly as the nanoclay content increased to 4%. The impact strength was 6% lower by the addition of 1 wt % nanoclay, it was decreased further when the nanoclay content increased from 1 to 4%. Finally, the water absorption of PP/bagasse composites was lowered with the increase in nanoclay content. Additionally, the coupling agent, 4 wt % MAPP, improved the mechanical and physical properties of the composites more than the 2 wt % MAPP. From these results, we can conclude that addition of nanoclay enables to achieve better physical and mechanical properties in conventional composites.

Influence of the recycled glass fibers from nonmetals of waste printed circuit boards on properties and reinforcing mechanism of polypropylene composites

“…In fact if it was reinforced using filler or fiber it could be used instead of other commodity thermoplastic and even engineering thermoplastics. [15][16][17][18][19][20][21][22][23][24] While the RGF recycled from nonmetals of waste PCBs still possessed inherent characteristics, such as high length diameter ratio, high elastic modulus, and low elongation. 7 Therefore, reusing of the RGF from nonmetals of waste PCBs as reinforcing fillers in the PP composites could represent a promising way for closing the recycling loop.…”

Assessment of Mechanical and Morphological Properties of New Poly Lactic Acid (PLA) / Wood Fibers / Nanographene Composite

“…Even when NG was added to composite structures at the rates of 0.75, 1.5, and 3 %, their tensile strength was lower than that of pure PLA. The reduction in the tensile strength of polymer with the addition of natural fi bers has been confi rmed in several studies (Nourbakhsh and Ashori, 2009). The addition of 30 % wood fi ber to PLA decreased the tensile strength as did the addition of 15 % wood fi ber.…”

Effects of Nanoclay on Tensile and Flexural Properties of Pineapple Leaf Fibre Reinforced Phenolic Composite

“…Many researchers studied nano filler/natural fibres hybrid composite such as nanoclay used as filler in bagasse reinforced polypropylene nanocomposites [14], graphene nano platelets used in kenaf fibers reinforced polypropylene nanocomposites [15], nanoclay as filler in bagasse flour reinforced recycled polyethylene [16], nanoclay used as filler in bagasse flour reinforced high density polyethylene [17], NCC extracted from oil palm shells used as filler in coconut fiber/kenaf fiber (woven mat) reinforce polyester hybrid composite [18]. Faruk and Matuana [19] studied wood flour/HDPE composites and investigated mechanical properties and found appropriate ratio of coupling agent content and nanoclay in composites improved significantly.…”
