Honeycomb composites were inspired by honeycomb weathering and beehives. Their aim is to reduce the amount of material being used, to consequently reduce the weight and cost of the final product. Honeycomb composites are made from different materials, such as stainless steel, aramid fiber, aluminum, and thermoplastic. They are commonly used in the marine and aerospace industries due to their lightweight and tough designs. The demand for these structures is increasing due to their relatively high shear and compression properties and their low density. Here are four of the advantages of these materials.
1. Reduced Cost
Many businesses prefer these lightweight materials to plastic and wood due to direct and indirect cost reductions. Honeycomb composites are cheaper to buy, handle, package, and transport. Being paper or metal-based products also makes them easier to dispose of while offering recycling cost-savings. This is because they are 100% renewable and recyclable.
2. Exceptional Strength-to-Weight Ratio
Honeycomb composites have become the ideal alternative to wood and concrete, especially in packaging and construction applications. They weigh about 4 to 5 times less than wood and 10 times less than concrete. They are strong and boast a high unidirectional compression resistance.
3. Fire and Fungus Resistant
These materials are usually multi-layered to provide high fire protection. Some structures come with cement-coated cells that ensure maximum resistance. Additionally, they are unaffected by water and most solvents, making them resistant to rot and corrosion.
4. Optimum Thermal Insulation
Honeycomb structures have a higher ability to dissipate heat thanks to their dead air spaces and polypropylene cell walls. This helps to prevent the accumulation of heat in the cells to avoid exceeding the heat deflection temperatures. Some options use foam to achieve even greater thermal insulation.
