Development of natural fiber composites with thermoplastics and thermosets finds applications in various fields, from agriculture to automotive. It can reduce the dependency on petroleum resources which causes several environmental problems. Natural fibers are renewable and biodegradable that reduces carbon footprint to the environment. Coir fibers are natural fibers used in the development of composites offers comparable properties with other mineral fillers. This article reviews different methods of coir fiber modification include alkali treatment, silane treatment, hydrogen peroxide treatment, sodium hypochlorite treatment, sodium periodate treatment coupled with p‐aminophenol and urea, treatment with benzene diazonium salt and maleated coupling agent. It also reviews composites of coir fiber with thermoplastic, rubber and thermoset plastics. Hybrid composites based on coir fiber are also being discussed. Thermoplastic composites such as biodegradable (PLA, PBS) and petroleum‐based polymers (PE, PP) and thermoset polymers include polyurethane, epoxy and polyester based composites also reviewed. Degradation and biodegradation studies were reviewed in the case of biodegradable polymers. Hybrid fibers of coir with other natural and mineral fibers have recently been used in composite industry has also been reviewed. All these composites show better properties. It can be used in different applications in the field of automobile, building and construction, consumer products and furniture. POLYM.

“…5,6 Some studies also claim that as the composite interface experiences increase in the fibre weight percentage, the fibre–resin bonding decreases after a point. 7 Further, studies also show that mechanical properties of composites vary with fibre arrangement in the composite and that longitudinally laid fibre composites displayed better mechanical properties than transversally laid fibre composites. 8…”

A successful attempt has been made to develop coir fibre composites reinforced with graphene, epoxy and carbon fibre. The carbon fibres were arranged in an intercalated manner, which is similar to the coir fibres. The percentage composition of graphene was varied as 1, 2, 4 and 6% by weight of the holding matrix. Suitable surface modifications were done by treating natural fibres by 5% NaOH and 0.3% KMnO4 for better adhesion of fibre and epoxy resin. Sonication and cetyl trimethyl ammonium bromide treatments were also done to achieve the fine scattering of graphene in the epoxy matrix in order to achieve better mechanical behaviour. Moulds were made as per D638 American Society for Testing and Materials (ASTM) standards. The treated fibres were then arranged in the mould by the conventional hand layup technique. Tensile testing was carried out to determine the mechanical properties of the composites. Two-way analysis of variance was used as a statistical tool to find the effect of parameters such as ‘Percentage composition of graphene’ and ‘Type of mould’ on the modulus of the composites. Fourier transform infrared spectroscopy was conducted to determine the interferential adhesion and homogeneous distribution of fibres in the composite matrix. At last, field emission scanning electron microscopy analyses were also done to the specimens before and after tensile testing to determine the morphology of different entities present in the composites.

“…Therefore it is clear that natural fibers after extraction from renewable sources must be subjected to chemical treatments. Several researchers reported on the various mechanical, thermal and other related properties of coconut fiber namely coir, husk and spathe [3][4][5] as reinforcement material with polymer matrix. In this connection a new fiber is identified from coconut tree named Coconut Inflorescence Fiber (CIF).…”

Natural fibers as reinforcement with polymer matrix have gained more advantage owing to its low density, high specific properties, biodegradability and abundant availability. In this connection an investigation has been carried out to make use of a newly identified natural fiber named coconut inflorescence fiber to reinforce with polyester resin. The natural fiber after extraction is subjected to mercerization treatment and the effect of mercerization on the surface of CIF was studied by FTIR and XRD analysis. FTIR spectrum analysis revealed the removal of functional groups present in the natural fiber owing to mercerization of CIF. XRD analysis shows improvement in crystalline size and crystalline index of the CIF as a result of mercerization. Samples of CIF/polyester composites were prepared by varying the length of the fiber as 10, 30, 50, 70 and 100 mm to be reinforced with different volume fractions of fiber/polyester resin as 10, 15, 20, 25 and 30% respectively and the specimens were cut as per ASTM standards for testing. Further samples were taken for testing of tensile strength and flexural strength. Results showed fiber length played a predominant role for the increase in tensile and flexural strength of the composites for 25% volume fraction. SEM analysis was done to predict the effect of fracture behaviour of the composite specimen.
