Abstract:
This study aims to analyze the effect of fiber orientation and massa fraction of ijuk
fibers on the static compressive strength of epoxy resin-based composites. Ijuk
fibers, derived from the Arenga tree, were chosen for their durability,
environmental friendliness, and cost-effectiveness. The study employed two fiber
orientations, continuous and random, and three fiber-resin massa fractions: 40:60,
50:50, and 70:30. Testing was conducted according to ASTM D790 standards using
a Universal Testing Machine. The results showed that composites with continuous
fiber orientation and a 70% fiber massa fraction exhibited the highest static
compressive strength, with an average value of 98.91 MPa. Conversely, random
fiber orientation with a 40% fiber massa fraction showed the lowest compressive
strength. This indicates that a well-ordered fiber orientation and high fiber massa
fraction significantly enhance composite strength. Therefore, the use of ijuk fibers
in continuous orientation and high massa fractions can be optimized for applications
requiring materials with high compressive strength, such as in the automotive and
construction industries.
