Abstract :
Sandwich composites are one of the material options that are increasingly
being used in several industries, including the aviation industry, because sandwich
composites have high stiffness and strength with light weight. This study aims to
determine the mechanical strength of hexagonal honeycomb sandwich Woven
Roving fiber with acrylic core on bending strength based on variations in the
direction of the fiber face layer/skin.
The research begins with the process of making face layer/skin composites
using the vacuum infusion method with variations in the direction of fiber angles,
acrylic cores with laser cutting. then the hexagonal honeycomb sandwich is cut to
size for bending testing on ASTM C393.
From the results of the bending test, it can be concluded that Hexagonal
Honeycomb Sandwich with fiberglass woven roving and acrylic core is known the
maximum acceptable load is around 1.13KN with an average of 1.05KN.
