Abstract
One advantageous embodiment of the present invention is a reaction-injection-molded galley cart (10) for an aircraft. This cart (10) includes a body, which is configured to move along a passenger aisle of the aircraft. The body is comprised of a one-piece plastic shell (12) having a first side portion (28), a second side portion (30) spaced apart from the first side portion (28), a top side portion (24) extending between the first side portion (28) and the second side portion (30), and a bottom side portion (32) extending between the first side portion (28) and the second side portion (30). This one-piece plastic shell (12) includes at least one layer (36) of a reaction-injection-molded material.
