Abstract

A composite level and a method to manufacture the composite level are provided. A composite level can have three layers of material. A first layer comprises a glass-mat material, a second layer comprises carbon fiber, and a third layer comprises a glass fabric material. A composite level can also have only two layers of material. At least one bubble vial is mounted on the level body. The method to manufacture the carbon fiber composite level comprises a pultrusion process wherein a fiber glass material and carbon fiber are saturated with resin and molded into a final shape.
