A composite panel includes a mold surface, a layer of gel coat applied to the mold surface, a wet laminate containing a resin applied to the layer of gel coat, a substrate of lauan or another moisture-carrying or moisture-absorbing material placed on the wet laminate, and a layer of a bonding promoter provided at the interface of the substrate with the wet laminate, additional to any amount of promoter(s) present in the resin of the wet laminate. Without previously curing or drying the layer consisting essentially of the bonding promoter in the solvent, each of the wet laminate, the bonding promoter, and the gel coat are simultaneously cured.

Composite panel containing lauan or other moisture-carrying or moisture-absorbing material using adhesion promoter

A method of manufacturing a composite panel with lauan or another moisture-carrying or moisture-absorbing material, and the panel so made, are provided. A layer of gel coat is formed on a mold surface, a wet laminate containing a resin is applied to the layer of gel coat on the mold surface, a substrate of lauan or another moisture-carrying or moisture-absorbing material is placed on the wet laminate, and the combination is cured. Prior to curing, there is provided a layer of a bonding promoter at the interface of the substrate with the wet laminate, additional to any amount of promoter(s) present in the resin of the wet laminate.

Method of manufacturing a composite panel containing lauan or other moisture-carrying or moisture-absorbing material using adhesion promoter and panel made using the method

A method of manufacturing a composite sheet includes perforating a reinforcement panel. A mold surface onto which the composite sheet may be formed is provided. At least one outer coat of material is applied onto the mold surface. At least one coat of resin and reinforcement material is applied over the outer coat to form a reinforcement layer. The perforated reinforcement panel is applied to the reinforcement layer, and the resin is forced into the perforations formed in the reinforcement panel, thereby bonding the reinforcement layer to the reinforcement panel.
