Abstract

In a preferred embodiment, a composite panel with a smooth outer surface, ready for painting with or without addition of primer, may be created by constructing a panel layup assembly upon a mold, the panel layup assembly including a composite panel having a core and a resin formulation, and a release film between the mold and the composite panel, where a smooth release surface of the release film is in contact with the composite panel upon construction; initiating curing of the composite panel at a first temperature within a lowermost ten percent of a curing temperature range of the resin formulation; continuing curing of the composite panel at a second temperature above the lowermost ten percent of the curing temperature range; and completing curing of the composite panel at a third temperature below the second temperature.

First claim

1 - 20 . (canceled)

21 . A smooth-surfaced composite panel, comprising:
a core layer; at least one reinforcement layer coupled to the core layer, the reinforcement layer comprising:
a fabric layer,
a first resin layer on a first side of the fabric layer, and
a second resin layer on a second side of the fabric layer, the first resin layer, being thicker than the second resin layer, wherein the first resin layer is facing the core layer; and
a paint-ready exterior surface, wherein the paint-ready exterior surface is the second resin layer of the reinforcement layer.

22 . The panel as recited in claim 21 , wherein the core layer is a honeycomb core.

23 . The panel as recited in claim 22 , wherein the honeycomb cores is an aluminum honeycomb core.

24 . The panel as recited in claim 22 , wherein the honeycomb core is a Nomex® honeycomb core.

25 . The panel as recited in claim 22 , wherein the honeycomb core is a Kevlar® honeycomb core.
