Abstract
Method for making light and stiff panels and structures using natural fiber composites. An improved composite material utilized in musical instruments. Bio-based industrial fiber such as flax, cellulose, hemp, bamboo, and jute combined with a core material such as foam, aramid honeycomb, carbon fiber or balsa wood, and a resin, serves as a replacement to traditional tone wood. In another embodiment, the bio-based composite has no core material but simply layers of fabric with resin. Another embodiment finds layers of the woven bio-composite as the core between outside layers of carbon fiber or aramid. In the case of a string instrument, bio-composites can be used to make a substantially hollow unitary body, neck and head as well as soundboard. Another usage is for the bracing material of the soundboard. In fact in its various forms, bio-composite can effectively replace all the old growth wood currently used.
