Natural fibers are displacing synthetic fibers as reinforcement in polymer composites due to their ease of processing,low cost,wide availability,biodegradability and *** this study,industrially discarded agro-waste areca fruit husk and tamarind fruit fibers were processed and used as reinforcement with unsaturated polyester resin to create a hybrid composite containing SiC nano filler *** SiC nano filler particles were varied from 1 to 4 wt.%in incremental steps of 1 wt.%with a constant 40 wt.%fiber reinforcement to determine its impact on the thermo-mechanical,morphological,wear and hygro-aging properties of the developed hybrid ***,the composite made of 3 wt.%SiC nano filler particles exposed overall better properties with better tensile(9.137 MPa),flexural(104.056 MPa),impact(7.983 J/cm^(2)),hardness(91.577 HRRW),wear(2.2×10^(-6)µm),crystallite size(7.9 nm)and thermal stability(360℃).Further advancement in weight percent of filler material,has worsened the properties due to poor dispersion and agglomeration factors by reducing the tensile,flexural,impact and hardness characteristics by 4.6%,6.4%,4.5%and 2.18%***,the microstructural investigation revealed the failure pattern,information on interfacial adhesion between the reinforcement,filler and matrix of the hybrid *** addition,the crystalline characteristics and availability of functional groups in hybrid polymer composite with 3 wt.%SiC nano filler particles were disclosed by X-ray diffraction(XRD)and Fourier Transform Infrared(FTIR)spectrum analysis,*** above findings reflects that the produced hybrid polymer composites suits well for interiors of automobiles and maritime interior applications to support loads with in the specified range.
