Review: Raw Natural Fiber–Based Polymer Composites

Ballistic Test of Multilayered Armor with Intermediate Epoxy Composite Reinforced with Jute Fabric

“…In addition to cost saving, the reader might also see relevant advantages in favor of the jute fabric composite application in our modern society. Environmental and societal benefits are currently associated with the use of a natural fiber [11][12][13][14][15][16][17][18][19][20][21][22] , which is renewable, recyclable and neutral with respect to CO 2 emission as well as a source of income and jobs in developing regions. These are today valuable factors to be considered for engineering applications and might contribute to change the current state of the art in MAS vests.…”

“…From the middle of last century, several natural fibers were incorporated into different matrices to be applied as engineering materials 11 . In past decades, an exponential growth in both research works [12][13][14][15][16][17][18][19][20][21][22] and industrial applications [23][24][25] has confer to natural fiber composites a prominent position owing to their technical properties (lightness, lower abrasion to molding equipments, toughness and strength) as well as economical, societal and environmental advantages 20 . Multilayered armors with a front ceramic followed by aramid fabric (Kevlar ™ ) are currently used against high velocity ammunition.…”

Ballistic Application of Coir Fiber Reinforced Epoxy Composite in Multilayered Armor

“…Recently the use of natural fabrics, fabricated from lignocellulosic fibers, as polymer composite reinforcement to be applied in MAS second layer was investigated 17,18 . In addition to much lower cost in comparison to synthetic aramid or UHMWPE fibers, natural fibers and fabrics are sustainable and neutral with respect to CO 2 emission responsible for global warming [19][20][21][22][23] . However a synthetic fiber like Kevlar™ 49, with a tensile strength of 3800-4200 MPa 24 , is much stronger than natural fibers that barely reach 1000 MPa 19 .…”

Fique Fiber Tensile Elastic Modulus Dependence with Diameter Using the Weibull Statistical Analysis

“…Today, in particular, the energy, pollution, cost and health problems of the glass fiber are motivating its replacement by lignocellulosic fibers [2][3][4] . Several review articles have discussed the advantages and drawbacks of the most important lignocellulosic fibers and related polymer composites [5][6][7][8][9][10][11][12][13][14][15][16][17] . Furthermore, specific publications were dedicated to already existing applications of lignocellulosic fiber composites in industrial sectors, from construction panels and doors 18 to automobile parts manufacturing [19][20][21] .…”
