“…Acrylic treatment of RH and jute showed a sharp O-H stretching peak at 3340 cm -1 which indicates the reduction of intermolecular hydrogen bonding. Acetylenic C-O stretching vibration (1107 cm -1 ) intensity is also increased due to the incorporation of acrylic -COOH group on the surface [22].…”

“…Patel et al found that acrylation of jute fibers improved mechanical properties of the composite along with a drastic reduction in water absorption [21]. Punyamurthy reported more than 30 % lower moisture absorption in acrylic treated natural fiber reinforced composites [22]. All the above studies primarily explored the effect of chemical treatments of natural fibers/fillers to improve the mechanical property of the composite and a few works has been reported that studied the effect on water absorption as well.…”

The development of green composites using different natural fiber reinforcements is an area of active research to reduce the environmental footprint. These composites have serious limitations with high water absorption and reduced mechanical strength. The objective of this work is to develop polymeric green composite form natural reinforcements -jute and rice husk, with improved water resistance and flexural characteristics. Rice husk and jute mat were chemically treated with acrylic acid and sodium hydroxide. The effective treatment conditions such as treatment temperature, time and concentration of the chemical to minimize water absorption, were determined. The effective acrylic acid concentration, temperature and time for acrylic treatment process were 10 volume percent, 60 o C and 4 hours for rice husk and 10 volume percent, 90 o C and 6 hours for jute mat respectively. The flexural properties were also reported for the composites. The surface chemistry, surface morphology and composition (hydroxyl, cellulose and hemicelluloses content) of the treated and untreated natural reinforcements were also analysed. It was observed that the acrylic treatment reduced the water absorption of the composites significantly with marginal reduction on mechanical property. Alkali treatment (using sodium hydroxide) improved the flexural strength of the rice husk reinforced composite, however it exhibits an adverse effect on water resistance properties.

“…Ironically, it is considered a waste from the cultivation industry of abaca 27 and costs only a fraction of that of synthetic fibers. The Philippines is the world's leading producer of abaca which supplies about 84% of the global demand, amounting to an annual average of 68,000 metric tons.…”

Fiber-reinforced polymer composites have received increased attention due to their environmental friendliness and sustainability, aside from at par-if not betterproperty enhancement achieved through fiber reinforcement over mineral-based fillers. The purpose of this article is to provide a comprehensive review on the various methods of fiber-based polymer composites preparation as well as their applications, particularly focusing on abaca-reinforced hybrid materials. Among the natural fibers available in the market, abaca fiber has been a major contender in the development of natural fiber composites. It has a great potential to be a renewable fiber source for industrial and technological applications owing to its inherent high mechanical strength, durability, flexibility and long fiber length. Impacts of different treatment strategies of abaca-based composites preparation resulting in property enhancements over bare polymer counterparts and that of synthetic fibers are discussed. Being eco-friendly and naturally sustainable, abaca fiber-reinforced composites can also exhibit better strength without substantial weight gaincharacteristics that have been exploited in various commercial and technological uses. How these enhanced properties of the resulting composites had led in a wide range of applications such as in the automobile and construction industries and other fields had been included as well.

Natural areca fibers were treated with sodium hydroxide, potassium permanganate, benzoyl chloride and acrylic acid to improve interfacial adhesion between the areca fiber and epoxy resin and to fabricate areca fiber reinforced epoxy composites with improved mechanical properties. The untreated and chemically treated areca fiber reinforced epoxy composites were prepared with 40%, 50%, 60% and 70% fiber loadings. The investigation of flexural strength was done for all areca/epoxy composites. Untreated and chemically treated areca/epoxy composites with 60% fiber loading showed higher flexural strength values. The acrylic acid treated areca fiber reinforced epoxy composites with 60% fiber loading showed highest flexural strength values amongst all untreated and chemically treated areca/epoxy composites with same 60% fiber loading.
