摘要

This paper discusses the bending stresses of the hexagonal honeycomb sandwich panel structure made of glass fiber reinforced polymer(GFRP)composite.The 1D axial hexagonal honeycomb sandwich panel structure consists of a honeycomb core and thin wallsheets.The plastic steel epoxy resin,polyaminoamide-bisphenol-A resin,and thermosetting resin were used as adhesive in every layer of the sandwich panel structure.The initial design is based on specific requirements that the panel will use as a chassis of the lightweight vehicle to achieve better fuel efficiency(Urban Concept with maximum vehicle weight is 300 kg).The axial load was dominantly on the chassis.The specimen is tested using the universal testing machine by three points bending method.The analysis is carried out through the response of adhesive between honeycomb core and wallsheets.The results show the bending stress of the honeycomb sandwich panel structure with three adhesives is more than enough for a lightweight chassis vehicle.
