Abstract: Described herein are details for designing and manufacturing enhanced shock and impact resistant helicoidal lay-ups by combining nanomaterials, variable pitch and partial spirals, Thin unidirectional fiber plies, hybrid materials, and/or curved fibers within a ply. The helicoidal structures created in the prescribed manners can be tuned and pitched to desired wavelengths to dampen propagating shock waves initiated by ballistics, strike forces or foreign material impacts and can arrest the propagation of fractures including catastrophic fractures. These enhancements open the helicoidal technology up for use in such applications as consumer products, protective armor, sporting equipment, crash protection devices, wind turbine blades, cryogenic tanks, pressure vessels, battery casings, automotive/aerospace components, construction materials, and other composite products.

Abstract: The present invention relates to a part of a luggage system, in particular a shell (510, 520) of a hard-shell case or trolley (500), comprising a natural fiber material. The present invention further relates to a method for the manufacture and a method for the repair of such a part. A part (21, 31, 400)of a luggage system is provided which comprises a fiber-reinforced material (100a, 100b, 100c), wherein the fiber- reinforced material comprises a natural fiber material (110a, 110b, 110c) and a matrix material (130a, 130b, 130c). The natural fiber material comprises at least one set of unidirectional fibers (120a, 120b-121b, 120c-123c) which are embedded in and/or impregnated with the matrix material.
