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.

Composite materials and structures

A container includes one or more hollow shell assemblies, each assembly having a first hollow shell including a first inner surface to cover a portion of a pressure vessel (PV) and a second hollow shell including a second inner surface attachable to the first hollow shell. The first and/or second hollow shells may include a fiber layer that may be at least partially impregnated with resin, and an energy dissipating material that is substantially concentric with the inner surfaces of the respective shells. The first and second hollow shells are attachable to one another to define a volume for at least partially enclosing the PV, and may be overwrapped via filament winding.

Containers and methods for protecting pressure vessels

Shock and impact resistant structures

A container includes first and second hollow shells respectively including first and second inner surfaces to receive a portion of a pressure vessel (PV). The first hollow shell includes a fiber layer that is and at least partially impregnated with resin, and an energy dissipating material that is substantially concentric with the first inner surface and disposed between the first inner surface and the fiber layer. The second hollow shell includes a fiber layer that is at least partially impregnated with resin, and an energy dissipating material that is substantially concentric with the second inner surface and disposed between the second inner surface and the second fiber layer. The first and second hollow shells are attachable to one another to define a volume for at least partially enclosing the PV.

This protective helmet comprises a rigid or semi-rigid external shell comprising a plurality of rigid or semi-rigid flaps joined together and a compressively deformable internal liner acting as a shock absorber, the latter also comprising several elements associated with said flaps. At least some of the flaps that constitute the external shell are capable of moving relative to each other at their respective means of connection and the elements that constitute the internal liner associated with the flaps in question are designed so that they retract inside the volume defined by the helmet during relative displacement of the corresponding flaps.

Foldable protective helmet

An element forming an inclined wedge, intended to be integrated with the front or rear end of the base plate of a snowboard binding, or directly with the upper face ( ) of a snowboard, is disclosed. The element includes an upper face ( ) intended to receive the bearing forces of the front or rear end of the sole of a boot, and having a mechanism for adjusting the angle of inclination, measured in a longitudinal plane, between the upper face of the element and the base plate of the binding or the upper face of the snowboard. The element may also provide a mechanism ( ) for adjusting the longitudinal position of the element in relation to the binding or snowboard.

Element forming an inclined wedge used in a snowboard binding

Interface plate mounted on a snowboard

An interface element ( ) used on a gliding board, said element being inserted between the sole ( ) of the user's boot and the top side of the board ( ) so as to take the thrust exerted toward the board by the user at least at the front end of the sole, and which comprises at least one zone ( ) made of a thermoformable material capable, after exposure to heat, of matching the imprint of at least the front end ( ) of the sole ( ) of the boot so as to fill the volume between the top side ( ) of the board and the sole of the boot ( ).

Interface element used on a snowboard

A Snowboard binding includes a baseplate intended to be mounted on a snowboard. A rear bow, is mounted on the baseplate ( ) at two attachment points and a highback is mounted so that it can pivot with respect to the rear bow. Further included are means for independently modifying the vertical position of each point of attachment of the bow ( ) to the baseplate ( ).

Snowboard binding

Highback for a snowboard binding intended to come into contact with the rear part of the user's boot in order to withstand the back thrusts thereof, having a median longitudinal plane of symmetry, which has a stiffer region located asymmetrically with regard to the median longitudinal plane of symmetry of the highback.
