“…Such increase in mechanical strength of composites with incorporation of treated LC fiber is an indication of enhanced chemical bonding between treated LC fiber and matrix and it is supported by results from XRD analysis of treated LC fibers. The composites using LC fibers having mechanical strength as mentioned above may be suitable for use as low strength materials such as house panels, doors, windows, and fiber board [22].…”

Tensile and compressive behaviour of resorcinol-formaldehyde (RF) matrix and its composites reinforced with fibers of Luffa cylindrica (LC) have been studied. LC fibers were subjected to chemical treatments such as alkali activation by NaOH followed by bleaching and acid hydrolysis in order to improve fiber-matrix adhesion. Both treated and untreated LC fibers are modified with calcium phosphate. The presence of hydroxy apatite, a polymorph of calcium phosphate and a major constituent of vertebrate bone and teeth, was confirmed from XRD peak of treated LC fiber. XRD analysis of the treated LC fiber has confirmed the crystalline nature of the chemically treated LC fiber by its crystallinity index. The effects of fiber loading of chemically treated and untreated LC fiber on ultimate stress, yield strength, breaking stress, and modulus of the composites were analyzed. The tensile and compressive modulus of the composites were increased with incorporation of both treated and untreated LC fibers into the RF matrix. The modulus of composites with treated LC fiber was enhanced compared to that of the untreated fiber composites. Furthermore the values of ultimate stress, yield stress, and breaking stress were increased with the incorporation of treated LC fiber in the composites.

“…[59] Using AESO-ST resins, biocomposites reinforced with natural fibers, such as flax, hemp, cellulose, recycled paper, and keratin fibers, have been prepared by resin transfer molding (RTM) or vacuum-assisted resin transfer molding (VARTM). [60][61][62][63][64] The resulting biocomposites exhibit much improved mechanical properties as compared to the pure resins. For example, the flexural strength and flexural modulus for a 34 wt % flax biocomposite are 64 MPa and 4.2 GPa, respectively, [62] which make them promising in applications that involve the automotive industry, farm machinery and vehicles, furniture, the construction industry, and even in office products.…”

Veggie-based products: Vegetable-oil-based polymeric materials, prepared by free radical, cationic, and olefin metathesis polymerizations, range from soft rubbers to ductile or rigid plastics, and to high-performance biocomposites and nanocomposites. They display a wide range of thermophysical and mechanical properties and may find promising applications as alternatives to petroleum-based polymers.Vegetable oils are considered to be among the most promising renewable raw materials for polymers, because of their ready availability, inherent biodegradability, and their many versatile applications. Research on and development of vegetable oil based polymeric materials, including thermosetting resins, biocomposites, and nanocomposites, have attracted increasing attention in recent years. This Minireview focuses on the latest developments in the preparation, properties, and applications of vegetable oil based polymeric materials obtained by free radical, cationic, and olefin metathesis polymerizations. The novel vegetable oil based polymeric materials obtained range from soft rubbery materials to ductile or rigid plastics and to high-performance biocomposites and nanocomposites. These vegetable oil based polymeric materials display a wide range of thermophysical and mechanical properties and should find useful applications as alternatives to their petroleum-based counterparts.

A brief review on the chemical modifications of lignocellulosic fibers for durable engineering composites

et al. 2015

A brief review has been presented on the existing methods to enhance the durability of lignocellulosic fibers (LCFs) for manufacturing composites for engineering applications. The free hydroxyl groups of the cellulose chains within LCFs tend to attract water molecules in moist environment, which may cause the fibers to swell and the cellulose chains to lose their integrity due to hydrolysis and oxidation imparted by the actions of biogenic enzymes or chemical factors, such as acidity, alkalinity, and salinity or UV irradiation. This study mainly highlights those technologies that present the modifications of cellulose main chain within the LCFs to improve the degradation resistance and mechanical strength. Detailed pros and cons of those chemical modifications have also been presented in this study with possible applications of the composites with special reference to durability.
