WHAT IS THE BEST CORING MATERIAL?
In many respects, wood is actually stronger than any material known-even so called space age material. What’s more, wood is far less expensive. How can wood be stronger than Kevlar and graphite fibers? It is stronger- strange as it seems. The answer lies in understanding “strength.” There are two critical types of strength: tensile and stiffness (the modulus of elasticity, or Young’s modulus-E). Both are measured in pounds per square inch (psi).
