Abstract :
Composite is a material formed from a combination of two or more
constituent materials through an inhomogeneous mixture, where the mechanical
properties of each constituent material are different. Composite materials generally
consist of two elements, namely fiber as a filling material and matrix as a binding
material for fibers that are formed on a macroscopic scale and physically fused.
The word composite is an adjective that means arrangement or combine. This
research can be a reference for making structures in the cross section of drones,
ships, brake linings.
The research method used is the Hand Lay-Up method. This study was
conducted using banana frond fiber filler with variations of Arahserat 0°, 45°, 90°.
The results obtained from the study were 0° fiber direction of 17,859 MPa, while
the lowest tensile strength was found in composites with 45° fiber direction
variations of 11,033 Mpa.
This made him faint that this type of composite with fiber direction already
met the air pressure standards for the manufacture of drones. While the highest
impact strength variation in fiber direction is 0.065 J/mm2, 45° is 0.0511 J/mm²,
while the lowest impact strength is found in composites with a 90° fiber direction
variation of 0.045 J/mm2.
