Abstract

Insulated panels play a crucial role due to their ability to offer a lightweight and cost-effective solution for various applications across different fields, characterised by diverse geometries. In this investigation, three distinct honeycomb shapes - hexagonal, RE-entrant, and starfish - each measuring 57 mm 120 mm with a thickness of 10 mm, are selected. Epoxy compounds reinforced with date palm, jute, and luffa fibres are utilised in the study. The design of these honeycomb structures was executed using CATIA V5R20® software, while their load-bearing capacity (under compression) was numerically analysed using the ABAQUS-CAE® calculation code. A comparative numerical analysis was conducted to evaluate the performance of the samples based on the different types of honeycombs employed. Following compression tests conducted at a rate of 0.2 mm/min, the findings revealed that the starfish structure exhibited the highest pressure-carrying capacity. Specifically, it sustained loads of 2220.75 N for the epoxy sample, 3107.74 N for the date palm fibre samples, and 3352.20 N for sisal fibre samples. Notably, the sisal fibre sample demonstrated the highest strength, 4338.33 N, while comparatively lower strength values were observed for RE-entrant geometries, particularly for the honeycomb reinforced with date palm fibres.
