Grant,

I'm not familiar with the wood you are thinking about and don't know how much softer it is than WRC but here are some things to consider:

When looking at the overall composite construction of fiberglass/wood/fiberglass, most of the FLEXURAL strength and stiffness comes from the material farthest from the center of the section. This is why I-beams are shaped the way they are. They put more material in the flanges, far from the center where it is more efficient. In this case it is the fiberglass that provides that strength and the wood core more or less acts as a spacer with very little load.

When considering an impact however, the hardness of the wood will play a much more significant role. Think of it this way, if you were to take two identical pieces of wet out glass (no wood), place one on a workbench and hit it with a hammer and take the other one and put it on a rubber mat and hit it with a hammer, the glass on the rubber mat will dent more easily.

I hope this helps.

Rich
