摘要

When former aerospace engineer and guitar aficionado Ellis Seal set out to design a composite acoustic guitar, he believed the inherent properties of carbon fiber could produce sound, payability, durability and consistency impossible in a wooden instrument. Today, his company, Composite Acoustics (Lafayette, La.), produces a guitar line that, his customers claim, justifies his work. The secret? Seal's AeoustieTailoring process, which permits customization of each model's tonal properties. Seal says many factors contribute to a sound signature: For instance, wooden guitars are assembled from separate body and neck components, but Seal's feature a one-piece body and neck to enhance stiffness. Instrument shapes are generated as 3D CAD models and master plugs are CNC-machined from aluminum. Resin-infused carbon/epoxy molds are pulled from the plugs. Reinforcements are cut on a CNC cutting table from Eastman Machine (Buffalo, N.Y.) and kitted. "We use 5.7-oz woven fabric, a 9-oz uni and some 30-oz stitched uni," says Seal, who specifies 30-35 Msi modulus, 500-600 ksi strength fiber. Dry reinforcements and core for the bodyeck arc positioned into the mold. A special core and comolded stiffening bars make the neck many times stronger, stiffer and more resonant than a wood neck, says Seal.
