Interfacial improvements in poly(3-hydroxybutyrate)-flax fibre composites with hydrogen bonding additives

Interfacial evaluation and durability of modified Jute fibers/polypropylene (PP) composites using micromechanical test and acoustic emission

“…Natural composite materials have some major advantages over conventional composite materials such as, biodegradable, environment friendliness, light weight, low volumetric cost, high specific mechanical properties, good sonic insulation properties [3,4]. However, natural composites have disadvantage for example, adhesion of the hydrophilic natural fiber as they are composed of lignocellulose, which contains strongly polarized hydroxyl groups with hydrophobic matrix is poor and the modification of fiber surface is necessary to improve interfacial adhesion [5][6][7].…”

Mechanical performances of surface modified jute fiber reinforced biopol nanophased green composites

“…To overcome this difficulty, these fibers should be modified chemically or physically [4]. Chemically modified surfaces decrease moisture absorption, and increase tensile strength [5,6] and wettability of fibers by matrix [7].…”

Composites of poly(lactic acid) with flax fibers modified by interstitial polymerization

“…Possible disadvantages are lower absolute strength and stiffness (in particular impact strength), variable fiber quality, moisture absorption that causes swelling of the fibers, and durability of the composites. 5 These properties need to be improved to achieve the optimum benefits of natural fibers, as a substitute for the existing glass fiber composites.…”
