Cellulose Microfibers as Reinforcing Agents for Structural Materials

Biocomposites from wheat straw nanofibers: Morphology, thermal and mechanical properties

“…The degree of polymerization (DP) is important to see the effect of the chemical and mechanical treatment on the breakage along the amorphous zones. The DP of the nanofibers is found to be 956 which is higher compared to microcrystalline cellulose [14].…”

“…Recent advances in producing bio-fibers, microfibrillated or nano-size fibers with high-strength and surface area, offer manufacturing high-performance composites from these bio-fibers [9][10][11][12][13][14]. Nakagaito and Yano [12] developed a new concept to produce a high-strength wood fiber based composite with bending strength of 370 MPa.…”

Mechanical properties of natural fibre reinforced polymer composites

“…During the past decade, a number of significant industries such as the automotive, construction or packaging industries have shown massive interest in the progress of new biocomposites materials. One of the most appropriate examples of this is the substitution of inorganic fibres such as glass or aramid fibres by natural fibres (Bledzki and Gassan 1999;Chauhan et al 1999;Chakraborty et al 2006). All these properties have made natural fibres very attractive for various industries currently engaged in searching for new and alternate products to synthetic fibre reinforced composites.…”

Examples of Natural Composites and Composite Structures

“…11b. The cellobiose molecule unit is the b-axis of the monoclinic crystal unit cell with a ¼ 0.83 nm, b ¼ 1.03 nm, c ¼ 0.79 nm, and β ¼ 84 (Chakraburty et al 2006). These cross-linked cellulose chains form crystalline or nanocrystalline regions or segments roughly 20-30 nm in length, separated by a noncrystalline, irregular chain region from bundles of elementary fibrils forming the 10-25 nm diameter cellulose microfibrils.…”
