A polypropylene fiber-based “self-reinforced” composite is being used for the shell of new X’Lite luggage in the premium Black Label line of Samsonite Corp., Denver. The hard-sided cases are pressure formed of lightweight Curv composite from Curv Composites, div. of Propex Fabrics, Austell, Ga. Curv is based on a woven fabric of highly drawn PP tapes. Layers of fabric are stacked and heated in a double-belt press until the surface of each tape melts to consolidate the fabric, without relaxing the tapes’ oriented core that provides the strength. Samsonite calls its X’Lite luggage “the lightest and strongest Samsonite ever.” Curv has the low density of pure PP plus notched Izod impact three to six times greater than PP/glass composites at room temperature and 25 to 30 times higher at -40 C.
