A poultry panel (20) for collecting manure comprising fiberglass reinforced layers (22, 30) with a preformed corrugated board (24) therebetween. The fiberglass reinforced layers (22, 30) consist of a resin-catalyst mixture (22, 30) containing calcium carbonate as a filler. The corrugated board (24) consists of two layers - one flat (26) and one corrugated (28). The poultry panel (20) provides a hard, rigid material which is easy to handle, inexpensive to manufacture, and resistant to corrosion. The poultry panel (20) is formed by spraying and laying successive layers of the resin-catalyst mixture and fiberglass sheets onto a metal form (44) with the preformed corrugated board (24) embedded between two such layers. The resulting composite is rolled to eliminate air bubble formation, cured until dry, removed from the metal form (44), and cured until hard.
An elongated panel for collecting poultry manure, the panel comprising:
In a process of forming a fiberglass reinforced synthetic resin panel by depositing successive layers of fiberglass batting and thermosetting resin, catalyst and solvent mixture onto a preform, and subsequently curing the mixture to a rigid, hard panel, the improvement which comprises:
