Analysis of jute and hollow conjugated polyester fibre reinforced nonwoven composites for functional applications Abstract

Abstract

Natural fibres are widely used in different applications and one of the important applications is insulation from thermal sound and mechanical application The research trends in the improvement of thermal and sound insulation of the Jute-based composite materials filled with polymer materials are studied by the researchers Jute fibres exhibit admirable heat and sound insulation properties but this has not been completely researched as yet Detailed information related to enrich the functional properties of jute nonwoven reinforced polymer composites based on its design of manufacturing density of composites morphology structural parameters of fibre batting number of layers and recent strategies are discussed for its high-performance potential applications Sandwich structure of nonwoven composite is produced by using a compressive hot pressing method It ranges from 2500 grams per square meter gsm to 3500 gsm Composite sample is designed using Box and Behnken model Considering 50 70percentage weight of Jute fibre content with 30 50percentage weight of Hollow Conjugated Polyester fibre ideal thickness of the composites is maintained in the range from 4 to 5 mm Thermal properties such as thermal conductivity thermal resistance thermal transmittance and thermal diffusivity were evaluated by considering three factors: weight of jute A weight of Hollow Conjugated Polyester B and thickness of the composite C The thermal conductivity of the composite material is determined by heat flow meter method ASTM C518 Experiment result will help to make a suitable standardized panel composite for thermal insulation It requires a design of 3600 gsm 51 49 parts of contribution of Jute Hollow Conjugated Polyester fibre with 50 mm thickness and a second design requires 3200 gsm 765 235 parts of contribution of Jute Hollow Conjugated Polyester fibre with 45 mm thickness of the composites The composite weight of 3280 gsm has shown optimized thermal responses it was predicted from response surface method analysis Contribution of Jute
