The effect of maleic anhydride modified polypropylene on the mechanical properties of feather fiber, kraft pulp, polypropylene composites

Abstract

Composites made of feather fiber (Ff), kraft pulp fiber (Pf), polypropylene (PP), and maleic anhydride modified polypropylene (MaPP) were tested in tension and three-point bend tests. Composite panels were compression molded from multiple plies of nonwoven, fabric-like prepreg manufactured with wetlay papermaking equipment. Composites containing all four materials were manufactured with MaPP substitutions for PP of 0 -10 wt % at 2 wt % increments. The best mechanical properties were observed with a substitution of 8 wt % MaPP. Composites containing either Pf or Ff were manufactured with MaPP substitutions for PP of 0, 4, and 8 wt %; mechanical properties improved with increases in MaPP content. The improvements in mechanical properties were attributed to fiber/ matrix interface improvement by the addition of MaPP. Scanning electron microscopy revealed evidence of improved interfacial bonding on the tensile fracture surfaces.

Comparative Studies of Mechanical and Interfacial Properties Between Jute Fiber/PVC and E-Glass Fiber/PVC Composites

“…Among all the reinforcement materials, glass fibers attracted much attention die to their better physicomechanical properties, good corrosion resistance, and good absorption and insulation properties. The most widely used glass fiber is E-glass fiber, which has good insulation properties and can maintain properties up to 815 C. The composition of E-glass fiber is 54.3SiO 2 -15.2Al 2 O 3 -17.2CaO-4.7MgO-8.0BO-0.6Na 2 O [1][2][3][4][5][6][7] .…”

Polyethylene reinforced with keratin fibers obtained from chicken feathers

“…Water is lost when the concrete dries and physical properties may have been maintained. Bullions et al [41,42] prepare composites of kenaf bast, wood pulp, and poultry feather fiber with polypropylene using a wetlay process. For feather fiber/PP composites, modifying PP with maleic anhydride to increase fiber/ polymer interactions increases the physical properties of the composites.…”

Fabrication, Mechanical Characterization and Interfacial Properties of Okra Fiber Reinforced Polypropylene Composites

“…The bast fibers such as jute, flax, hemp, ramie, sisal, kenaf are presently using as reinforcement in polymer composite and many efforts have been made by researchers to establish natural biodegradable fiber as substitute of synthetic fiber to use effectively in the composite material. Several studies reported that incorporation of lingo-cellulosic fiber improves the physicomechanical properties of polymer matrices in the composite material [1][2][3][4][5][6][7][8][9][10][11][12][13]. Scientists prefer thermoplastic composites than thermoset because of low production cost and lower processing cycle.…”
