Abstract

Simple mixing and hot pressing methods were used to make high strength and light-weight composite from oil palm empty fruit bunches (OPEFB) using PVAc as an adhesive and silica nanoparticles as a filler. The mechanical strength of the composite was examined in term of compressive strength. The simple mixing method was used to mix composition with PVAc and silica nanoparticles. Silica nanoparticles were added as filler. Hot pressing method was used to press the mixed composites at a pressing pressure of 85 MPa, pressing temperature of 150 °C, and pressing time of 20 minutes. The optimum composition in term of compressive strength for the strongest composite had a mass ratio of OPEFB/PVAc of 13 : 2 and obtained a compressive strength of 82,88 MPa. Higher compressive strength of 100,39 MPa was obtained by adding the silica nanoparticles at a mass ratio of OPEFB/PVAc/silica nanoparticles of 13 : 2 : 0,75. At pressing pressure of 100 MPa, pressing temperature of 150 °C, and pressing time of 20 minutes, we found compressive strength of 115,35 MPa. Data analysis of XRD showed that the used silica nanoparticles were in amorphous phase or had broad pattern. The compressive strength data showed that the composites were stronger than the composites made by Masturi and Kumagizuri, and also stronger than the ordinary wood-based composites. Thus, the composites are feasible to be used to replace wood-based composites, especially in furnishings.
