| Summary: | In this work, sandwich composite properties were investigated by addition of coconut
coir (CC). Fibres in the polyurethane foam cores ranges fiom 0 to 20 wt.%. Glass fibre reinforced
epoxy panels were used as a skin and polyurethane foam as a core, these materials adhesively
bonded to keep the whole structure attached with each other. Sandwich composite skins and coresicin
bonding were attained via adhesive bonding technique. While polyurethane foam reinforced by
coconut coir fibres were manufactured by using one shot process and polyurethane moulding
method. Sandwich composite panels with different coir fibres compositions were subjected to the
density test, weight per area test and flexural testing in order to investigate their physical and
mechanical properties. From the experimental results and analysis, it was found that the sandwich
composites with 10 wt.% of coir fibres offer higher mechanical properties. |
