ASME-RTP 1 Balsa Wood
ASME-RTP 1 Balsa Wood
(OP)
Greetings,
This post is to satisfy my own curiosity and there is no immediate need for an answer. I was reading through the ASME –RTP 1 and there is a section on the use of balsa wood cored plates (Part 4 Fabrication). The section gives the requirements for balsa wood laminates. My question is why balsa wood? Why not some of the harder species like oak, hickory or even pine? What special properties does balsa wood possess?

Its got to be weight, or lack of it to be precise!

Pity you can't edit posts! I forgot to add, it also has very good crush resistance when sliced up and used "End grain", this combined with its low density made it very popular for use as a core material before honeycomb style materials appeared.

While it does add some strength - the main purpose of the middle layer is just filler, to get the laminate strength away from the center (add moment of inertia). Analagous to the additional strength of a deeper wide flange beam.
