Impact and Compression Study of Agel/Carbon Hybrid Composites with Layer Variations
Keywords:
Low Velocity Impact, Compression After Impact, Hybrid CompositesAbstract
The development of eco-friendly composite materials encurages the use of natural fibers like agel (Corypha gebanga). This study aims to analyze the failure response due to Low Velocity Impact (LVI) dan Compression After Imapct (CAI) strength in carbon and agel fiber hybrid laminated composites. Specimens were fabricated using the Vacuum Assisted Resin Infusion (VARI) method with a 60:40 fiber to epoxy volume fraction. Agel fibers were pre-treated with 5% NaOH alkalization for 2 hours. This research varies the stacking sequence and fiber orientation. Based on the initial hypotesis, the laminate configuration with carbon fibers on the outermost layers (C/A/A/C) is predicted to yield the highest peak force capacity and the most optimal residual compressive strength. The results of this study are expected to provide material design guidelines for structural applications requiring high impact resistance.
