INDIA. I. Introduction Nature created materials is the munja fibres which are abundantly available, eco-friendly and have renewable in their behavior. The cultivation and on growing harvesting and primary processing conditions to extract the fibre will dictate the homogeneity. On one end the natural fibres are light in weight which is extremely advantageous but due to its low density can be disadvantageous in processing since the fibre tends to emerge from the matrix specifically liquid resins. Moisture absorbing tendency is another bottleneck to the natural fibres which resulted in the delamination of the composites. Hence right extraction method of fibre and suitable processing method to manufacture the composites by reinforcing the fibre are the vital foremost tasks in dealing with NFRPC. Several researchers have put their effort in manufacturing composites using variety of natural fibres (with and without chemical treatment), matrices (thermoplastic, thermosetting plastic etc.) and characterized them for their physical, mechanical, and thermal properties. Out of that a part of authors have focused on making and characterization of the composites reinforced with short palymyra palm fibrous waste, stem, stem long, munja, palm/jute, fibre palm/banana, borassus fruit fibre in various matrices and the highlights of the same are described below in the order of borassus fruit, short, short hybrid, long, long hybrid palmyra palm fibre reinforced polymer composites. Sudhakara et al. [1], achieved more flexural strength, tensile strength, modulus, modulus and impact strength for alkali treated/MAPP composites by 4.5, 17, 17.2, 9 and 10 % respectively in case of borassus fruit fibre reinforced polyester composites. Dabade et al. [2], extracted the palmyra palm fibres from stem and also extracted by chemical means (soaking in 1 % NaOH) solution. They have reported that palmyra fibres up to 50 mm length in the polyester composites have shown increasing trend of flexural strength, and is decreasing thereafter. At 50 mm fibre length, the composites exhibited maximum tensile strength of 42.65 MPa and thereafter it is decreasing. The mechanical properties of palmyra/banana fibre reinforced composites have shown optimally increased properties at 2 cm fibre length when compared with 3 cm and was noticed by Venkatesha Gowdagiri Prasanna et al. [3]. Fibrous waste formed during separation of palmyra palm leaf, stem base is used by velmurugan [4], to form palm fibrous waste (pfw) reinforced polyester composites. They have also prepared pfw/glass FRP composites to compare and contrast the results of the short fibre composites without hybridization. The addition of pfw resulted in improvement in impact strength but they have unable to achieve the tensile, flexural strength with increase in fibre content in the composites. Thiruchitrambalm et al. [5], studied the effects of chemical treatment on palmyra palm leaf stalk fibre reinforced polyester composites. They have achieved an improvement in tensile strength by 60 % and modulus by 60 % respectively with the reinforcement of mercerized and benzoyl – treated fibre composites respectively whereas permanganate – ABSTRACT: The incorporation of natural fibres such as munja fiber composites has gained increasing applications both in many areas of Engineering and Technology. The aim of this study is to evaluate mechanical properties such as flexural and tensile properties of reinforced epoxy composites. This is mainly due to their applicable benefits as they are light weight and offer low cost compared to synthetic fibre composites. Munja fibres recently have been a substitute material in many weight-critical applications in areas such as aerospace, automotive and other high demanding industrial sectors. In this study, natural munja fibre composites and munja/fibreglass hybrid composites were fabricated by a combination of hand lay-up and cold-press methods. A new variety in munja fibre is the present work the main aim of the work is to extract the neat fibre and is characterized for its flexural characteristics. The composites are fabricated by reinforcing untreated and treated fibre and are tested for their mechanical, properties strictly as per ASTM procedures.
