The bowl dell'Ovation was composed mainly of layers of fiberglass omnidirectional impregnated resins. All for the thickness of 1mm.
think we're talking about a product made in the early '60s, when the available technology was not so developed. Kaman's engineers took them almost 2 years of research to find the formulation of an acoustic material other than wood. In this period were made at least 70 original drawings for shaping the new guitar. The form chosen, the most efficient and robust was finally a semi-parabola-round-like that of a parabola
for television or the human ear.
The sound produced by the baby bowl, they said, was "immeasurable" richer, fuller and deeper than any other guitar made of wood at the time.
In addition, the wood absorbs energy instead of returning it (it should be considered at that time did not exist for pick-up noise) while the fiber vibrating bowl so chemically similar to the wood that was glued. Furthermore, the cellular structure of wood, accompanied by various oils present in it of course, varied considerably over time and between one instrument and the other making it difficult to have vibration characteristics constant.
In search of new material to the Kaman utilized all studies performed on the vibration of bodies and substances and materials available to a company producing helicopters and equipment aerospace subject to strong vibrations. Finally, they found that the material chosen, called lyrachord could be modeled accurately in its shape (bowl) without additional bracing. He had a molecular structure that can be "tuned" chemically and heat treatment up to a certain degree of resonance, which remained constant over time and with no possibility of cracks and changes due to changes in temperature and humidity.
was indeed an ideal substance and one of the greatest contributions to the development of the acoustic guitar in recent years. .... to be continued!
