Characterization studies on Calotropis procera fibers and their performance as reinforcements in epoxy matrix

Intrinsic cellulosic fiber architecture and their effect on the mechanical properties of hybrid composites

“…4, it is obvious that the area under the curve is high for CN20_LC10 exhibiting the toughness of the samples due to the Cocos nucifera fibers. The flexural strength of these composites is quite similar to the flexural strength of Calotropis procera fibers reinforced composites and rice straw/chicken feather reinforced hybrid composites [41,42].…”

“…It is because of the special, natural and unique knitting vascular system of Luffa cylindrica fibers resembling a uniform mat-like structure that increases the surface area of the Luffa cylindrica fiber per unit area of the composite [46]. This increase in the surface area leads to the increase in the contact area, bonding ability and interfacial adhesion between the matrix and reinforcement enabling efficient stress transfer resulting in increased impact strength similar to the polymer composites reinforced using Calotropis procera fibres and jute/ banana fibers [41,47]. Table 4 and Figure 5 show the impact strength of the hybrid composites.…”

Chemical Constituents and Uses of Calotropis Procera and Calotropis Gigantea – A Review (Part I – The Plants as Material and Energy Resources)

“…Lately, the use of fibers from C. procera as a reinforcement material for thermoplastic composites was suggested, with polypropylene (PP) as matrix polymer and maleated polypropylene Epolene G-3003 as coupling agent [54]. C. procera fibers were tested as reinforcement material in an epoxy matrix, too [55]. Fibers of C. gigantea have gained attention as well, with studies on purifying the fibers for mass production [56], and on new bleaching [57] and dyeing techniques [58,59] to make them commercial products, although dye uptake and dye fixation on the fibres remains a challenge [58].…”

Morphology and damage mechanism of lignocellulosic fruit fibers reinforced polymer composites: a comparative study

“…Many researches are currently taking place in this domain in search of new fibers that could be used to produce ecofriendly industrial components owing to their abundant availability, ecological properties, less production cost, minimal tool wear and low energy requirement are some major reasons that make the cellulose based natural fibers as reinforcements for polymer matrix composites, thereby reducing the dependence of synthetic fibers [1][2][3]. Stiffness requirements for light and non-structural applications, thermal, vibro-acoustic properties for the manufacture of automobile interiors, door panels are achieved by the natural based materials [4]. The mechanical properties of the composites reinforced with natural fibers largely depend on the constituent fibers, their polarity, matrix and interfacial adhesion that exist between the matrix and fibers [5].…”

“…Kenaf bast fibers reinforced polyester composites have showed that 20 wt% fibers resulted in good tensile and flexural properties, while 10 wt% of kenaf bast fibers resulted in good impact strength [10]. Yoganandam et al [4] have fabricated composites using handlayup technique with fibers extracted from Calotropis procera stem as reinforcements. The mechanical properties of the composites are seen to increase with increasing fiber content and maximum flexural, impact strength of the polyester composites are obtained for composites containing 30 wt% of fibres.…”
