| Summary: | Natural fibres offer environmental benefits such as biodegradable and can be obtained
from renewable resources. In term of strength, natural fibres are still inferior by the
synthetic fibres. However, there is lack of investigations done to characterise and
compare different types and orientation done on the natural fibres. The basic purpose of
the study is to determine the mechanical and physical properties of sugar-palm fibres
under various treatment processes, to analyse the performance of mechanical and
physical properties of different type of orientations and to compare the obtained
properties with other natural fibres. The study starts with preparation of the sugar-palm
fibres, followed by surface treatments by alkali and acid solutions and weaving the fibre
into a woven fibre before putting it into the mould. After dried, the composite board
was cut into specimens and tested for 3-point flexural test and tensile test. Surface
morphological analysis by using SEM machine was done before doing the data analysis.
The outcome of the study proved that the chemical treated fibres has higher tensile and
flexural properties compared to the untreated fibres where the value of tensile stress for
alkali treated, acid treated and untreated fibres are 27.92 MPa, 26.41 MPa and 25.75
MPa respectively. In addition, the value of flexural stress for alkali treated, acid treated
and untreated fibres are 81.16 MPa, 79.07 MPa and 41.34 MPa respectively. As a
conclusion, woven sugar-palm fibre reinforced epoxy composite is appropriate to use as
a replacement for the synthetic fibre such as glass and carbon fibre since it has good
tensile and flexural properties. With these properties, it is proved that the treated sugarpalm
fibre composite can withstand high stress load during operation compared to the
untreated sugar-palm fibre composite. |
