Abstract
A drum shell and method of making same. A first layer of carbon fiber material is rolled into a cylindrical shape. Next, a layer of foam is wrapped over the cylinder of carbon fiber material. Finally, a second layer of carbon fiber material is rolled over the foam layer. In a more specific implementation, several sheets of carbon fiber soaked in an epoxy resin are rolled on a cylindrical mold to provide the first and second rolls thereof. After the application of the second set of sheets, the shell is vacuum dried and cut to desired lengths to complete the construction.
