Abstract
A composite panel includes a sheet having layers. At least two of the layers are kraft paper. The layers re stacked on each other and adhered together with a resin. The sheet is corrugated with alternating peaks and valleys disposed sequentially along an axis of the sheet. Each peak has a plateau and each valley has a base. Each of the plateaus and the bases lies in a plane being substantially parallel to the axis of the one sheet.
Claims21
A composite panel, comprising:
- a sheet having layers, at least two of the layers being kraft paper, the layers being stacked on each other and adhered together with a resin, the sheet being corrugated with alternating peaks and valleys disposed sequentially along an axis of the sheet, each peak having a plateau and each valley having a base, each of the plateaus and the bases lying in a plane being substantially parallel to the axis of the one sheet.
The composite panel as defined in claim 11, wherein the first radius of curvature is different than the second radius of curvature.
A method of forming a structural composite panel, comprising:
- stacking layers and adhering the layers together to form a sheet, at least two of the layers being kraft paper;
- and
- corrugating the sheet along an axis to form alternating peaks and valleys disposed sequentially along the axis, each peak having a plateau and each valley having a base, each of the plateaus and the bases lying in a plane being substantially parallel to the axis of the sheet.
