Fiber Layer Shapes and Fiber Layer Number Effects on Toughness of Nata De Coco Fiber and Polyester Matrix Composite
- Bagikan:
Composites are one of interesting material used lately, because it is lighter
than metal relatively and also strong. So then development and application of
composite material is rapidly increase, particularly polymer matrix composite.
Polymer matrix composite applied as an alternative metal-based material.
Natural fibers are more popular used as reinforcement for polymer matrix
composite than synthetic fiber such as fiber glass. In additional, natural fibers
are friendly environment, more economic, and also excessive availability in
nature are some consideration to choose natural fiber.
The problem to produce a composite is how to determine the ratio of
matrix and its reinforcement, whereas matrix and reinforcement ratio would
be able to deliver good mechanical properties. Polyester is used as matrix and
nata de coco is used as reinforcement in this research. Fiber alkalization
treatment and acetone liquid immersion were applied for nata de coco fibers
before it composed with the matrix. Impact testing was applied to obtain the
toughness of composite and Scanning Electron Microscope (SEM) was used to
analyse the fracture surface of composite.
Based on the result can be determined that three fiber layers were the best
ratio inside matrix to deliver optimum mechanical properties. On the other hand,
adding holes in the fiber was reducing the toughness of composite.
