Summary: | Rice husk, stem and straw are by-products as of rice milling process. However,
they can be economically utilized to generate energy, used as bedding materials for
animals or burnt as land filling. Another alternative is to use these by-products as
reinforcing materials to produce rice bio composites with promising potential. This
project focuses on the potential of rice husk, stem and straw to produce composite
materials by investigating the mechanical properties of the composites. Particles of rice
husk, stem and straw were used as reinforcing fillers while polypropylene was used as
matrix. The preparations as well as testing of specimens have been carried out according
to ASTM D 638 for tensile test and ASTM D 790 for three point bending or flexural test.
The results from this project show that rice bio composites are indeed have the
potential to produce materials with good mechanical properties. Rice husk composites
which have 8.23 MPa of Ultimate Tensile Strength, 0.79 GPa of Young’s Modulus and
32.64 MPa of flexural strength proves to be the most versatile material out of those byproducts.
However, other parts of paddy such as stem and straw should not be ignored
considering that the mechanical properties of composites produced from these parts are
also acceptable. Somehow, the combinations of different parts of rice to produce
composite are beneficial and economically profitable based on the fact that these parts are
usually thrown away after milling process has been done. |
