Hi guys,
New in this forum. Great to see so many solutions and help provided by the members here.
I am looking to replace aluminium honeycomb with foam as a core material in the marine environment. There are some advantages listed below but maybe you guys can help with more detailed comparisons in terms of the technical differences between the 2 core materials. Feel free to add in the advantages or disadvantages below. Cheers.
Advantages of the foam panels are as follows.
• Lightweight - comparable weight to aluminium honeycomb. • Best cost to performance ratio, >200% saving compared to similar aluminium honeycomb panels. • Specific compression strength of the foam core was 72% higher than the compression strength of the aluminium core • No potential corrosion problems in a salt-water environment like aluminium honeycomb • Specific \ multi-layered density layup for individual requirements • Greater thermal and acoustic insulation compared to aluminum honeycomb • Can be processed into flat, curved or even compound shapes. Varying thickness within a panel can be achieved with a custom build. • Good screw retention for higher densities
Disdvantages of the foam panels are as follows.
• Lower flash point as compared to aluminium honeycomb(~600°C) versus foam (~200°C) • Lower tensile strength per weight ratio
