Abstract
For successful employment of natural fiber reinforced composites in structural applications, it becomes necessary to design them in such a fashion that they retards flame propagation and moisture sorption. In this context, an experimental study has been carried out to analyze the effect of layering pattern on flammability and moisture sorption of hybrid biocomposites. The different layered hybrid composite boards [pineapple/coir/pineapple (PCP), coir/pineapple/coir (CPC), bilayer (P/C), and Intimately Mixed (IM)] were developed by hand lay-up technique, keeping the volume ratio of pineapple and coir 1:1 and total fiber to matrix region ratio 40:60. In order to characterize the flammability and hydrophilicity of developed materials, the UL-94V, UL-94HB, flame penetration, and water absorption tests were carried out as per ASTM standard. The experimental results demonstrate that the CPC hybrid composite has higher resistance to burning and penetration of water molecules as compared to the other patterns. In comparison with PCP and Bilayer (P/C) composites, the intimately mixed hybrid material exhibits a lower rate of burning and total mass loss. Moreover, the Intimately Mixed (IM) hybrid composite absorbs 44.32% and 34.87% less water than that of PCP and Bilayer (P/C) composites respectively.
