Novel insulation panels development from multilayered coir short and long fiber reinforced phenol formaldehyde polymeric biocomposites

Abstract This study investigated about the developments of insulation panels from multilayered coir long and short fiber reinforced phenol formaldehyde polymeric (PF) resin. The lengths fibers (CLF) were within 3 mm, whereas (CSF) ranged 0.1 mm to 1.25 mm. Four composite 360, 680, 800, 1000 kg/m densities developed by employing hot pressing technology. thermal conductivity, microstructural, mechanical, physical properties investigated. Perceived conductivity values 0.046280 (0.000494) 0.062400 (0.001146) Wm ?1 k composites demonstrating superior properties. Moreover, current also found that mechanical showed improvement with increase density. Low-density fiberboards had lowest performances compared high-density panels, exception density, in which agglomeration occurred. Furthermore, all display potentiality for use as effective materials. FTIR (Fourier transform infrared spectroscopy) analysis shows an efficient bonding between cellulosic materials PF overall characteristics especially medium fiberboard, show prominent potential industrial production units fulfilling consumer requirements.
