Lightweight FRP Composite Ladders

Luna Innovations will be developing lightweight, flame retardant composite inclined ladders for use aboard naval vessels. The proposed program involves 1) designing composite based ladders meeting Navy specifications for shipboard use, 2) producing environmentally sound flame retardant, fiber reinforced polymer (FRP) composites for use as inclined ladders, and 3) making FRP composite parts proving the proposed composite materials have mechanical and fire retardant properties suitable for use in the designed ladders. The flame retardant FRP composites of this proposal are based on a novel method of imparting fire resistance, and the proposed FRP resins have been shown to be self-extinguishing in preliminary tests. The proposed flame retardant offers advantages of being environmentally sound with minimal off-gassing of toxic compounds during combustion. In addition, the proposed flame retardant resins are expected to have comparable mechanical properties with potential improvements in toughness compared with commercial non-flame retardant resins. Luna has also identified a thermoset resin with thermal stability to meet high temperature load requirements. This development will contribute to the Navy's goal of improving shipboard safety while reducing load weight and cost.
