Influence of Woven Glass-Fibre Prepreg Orientation on the Flexural Properties of a Sustainable Composite Honeycomb Sandwich Panel for Structural Applications

Owing to the high potential application need in aerospace and structural industry for honeycomb sandwich composite, study on flexural behaviour of composite structure has attracted attention recent decades. The excellent bending structures is based their facesheet (FS) core materials. This research studied effect woven glass-fibre prepreg orientation panel. A three-point test was done as per ASTM C393 standard by applying a 5 kN load different angles panel: α = 0°, 45° 90°. results show that most panel almost same failure mode during test. Additionally, 0° angle shows higher maximum prior first occurrence compared others due flexibility but lower stiffness. In addition, angle, stress modulus, which directly depend upon value obtained experimental analytical prediction deflection good agreement. According result obtained, it revealed panels with an alternative 90°, especially when better main purpose. final this can be applied enhance properties glass-fibre-reinforced polymer (GFRPC) cross-arm existing used transmission towers.
