Abstract :
This research aims at bending testing, reverse engineering and dimensional
comparison (comparison of shapes) of the pandan thorn leaf fiber composite
whether it is feasible as a drone frame material and bending testing to find out
whether pandan thorn leaf can have a bending stress and strain value that can
compete with other types of composites.
The research method used in the manufacture of composites is using the
hand-layup method and using an epoxy resin type and then comparing it with
carbon fiber. The reverse engineering method is redesigned using Autocad. In the
comparison of dimensions, re-measurements are carried out according to the
results of the redesign in the reverse engineering process.
From the results of the analysis, it was found that the stress values of the
specimens met the standard values, namely specimen 1 (34.666 MPa), specimen 2
(39.188 MPa) and specimen 3 (44.481 MPa) on pandan thorn fiber specimens
with variations in thickness of 5mm and specimen 3 (44.481 MPa) on fiber
specimens. pandanus thorn variation 2 mm. The stress value that occurs in the
pandanus thorn fiber composite is not proportional to the bending stress value of
the carbon fiber. The strain value of pandan thorn is higher than thar the strain
value in carbon fiber. In reverse engineering and dimension comparison, the
dimension value is almost the same as the real object dimension value, with the
highest error percentage 3.56%.
