Isotropic Properties of Polyester/Basal Laminate Composites at Weave Angle Orientations Based on Tensile Strength

Abstract:

Composite research has been conducted using natural materials that do not have a negative impact on the environment. In this study, the fibers used are environmentally friendly basalt fibers, which are derived from basalt rock. In studies of the mechanical properties of materials, isotropic means having identical values in all directions. Isotropic materials are useful because they have the same physical properties in all directions, and their behavior is easier to predict. The research question is: What are the isotropic properties of basalt polyester fiber laminate when tested for tensile strength in two dimensions, specifically the X and Y planes of the test specimen. The purpose of this study is to determine the isotropic properties of polyester composite basal lamina specimens consisting of 7 layers of fibers oriented at 0°, 15°, 30°, 45°, 60°, 75°, and 90°, as well as a 10-layer fiber specimen with fiber orientations of 0°, 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, and 90°. This study uses variations in specimen cutting angles, namely 0°, 10°, 30°, 45°, 50°, 60°, and random. The tests to be conducted are tensile tests using the Tensilon RTG-1250 testing machine (ASTM D 638). The highest tensile strength test results were obtained by specimens with a 0° cutting angle, with an average tensile strength of 134.907 MPa in composites with 7 layers of fiber and 180.922 MPa in composites with 10 layers of fiber. The lowest tensile strength was observed in specimens with a 45° cutting angle, with an average tensile strength of 110.46 MPa in the composite with 7 layers of fiber and 126.531 MPa in the composite with 10 layers of fiber. The 7-layer fiber composite is more isotropic than the 10-layer fiber composite, as evidenced by better adhesion properties observed via SEM and improved mechanical interlocking.
