Foam aircraft construction
WebFoam is stronger, costs less, takes less time to build and repair, and is more precise, too. EPS Styrofoam, by its nature, is made up of a strong honeycomb like structure. It has a compression strength of 1,000 pounds per square foot. You can stand on a foam wing. Foam is a lighter material than balsa. WebLAST-A-FOAM ® FR-6700 FR-6700 Aerospace Grade is a CFC-free, rigid, closed-cell, flame-retardant polyurethane foam available in densities ranging from 10 to 25 pounds per cubic foot. It exhibits a high strength-to-weight ratio because of its cellular structure and cross-linked resin.
