Abstract :
In the current era, composites are one of the materials that are often found in
the automotive industry. The advantages of this material include light weight, good
mechanical ability and corrosion resistance. Composites consist of matrix and
reinforcement. The matrix is usually a polymer that is either a thermoset or a
thermoplastic. While the reinforcement consists of synthetic fibers, natural fibers
and particles or powders.
This study aims to determine the effect of variations in alkali immersion time on
the tensile strength of the arenga pinata fiber-reinforced polyester composite,
fracture morphology, and the feasibility of the research results as a car dashboard.
Composites were made using the hand lay-up method, polyester 157 BQTN (UPRs),
0° fiber orientation, 190 mm fiber length, 10% fiber volume fraction and 1% matrix
weight catalyst. The results of the tensile test on arenga pinata fiber composites
with variations in alkaline immersion time of 60 minutes have an average tensile
stress of 28,22 MPa. The variation of 90 minutes alkaline immersion time has an
average tensile stress of 33,61 MPa. The variation of alkaline immersion time of
120 minutes has an average tensile stress of 22,18 MPa. And for variations in
immersion time of 150 minutes it has a tensile stress of 31,06 MPa.
