Effect of CaCO_3 and Wood Flour Filler on the Compression Strength of Coconut (Coir) Fibre Reinforced Polymer (FRP) Composite

摘要

Compression test specimens were produced from the composite material of fibre reinforced polymer (FRP). These specimens were tested on the compressive testing machine. The results obtained showed that 5% coconut fibre volume fraction with 95% volume fraction of polypropylene matrix gave compressive strength value of 39.3 Mpa. However, it was observed that when 15% volume fraction of CaCO_3 and wood flour filler each were added, the compressive strength increased from 39.3 Mpa to 53.3 Mpa and 39.3Mpa to 43.7Mpa respectively. This observation was discussed in respect of the two fillers.
