Abstract
The present disclosure relates to the customization of a composite layer material for absorbing or dissipating mechanical energy under impacts or vibrations. The composite layer material comprises at least a support layer of a resilient material, said support layer having recessed fluid-tight microchannels comprising a fluid, wherein the channel section and fluid viscosity is such to dampen the external load by the constricted fluid flow through said microchannels. Therefore, the present disclosure relates to a maximization of safety and/or comfort.
Claims19
A composite layer material for dampening external dynamic load, comprising:
- at least a support layer of a resilient material, the support layer having recessed fluid-tight microchannels comprising a fluid, wherein the microchannel section and fluid viscosity dampens the external dynamic load by constricted fluid flow through the microchannels, wherein the at least one support layer comprises an impermeable resilient solid material selected from the group consisting of:
- cork, expanded polystyrene, expanded polypropylene, ethylene vinyl acetate, and combinations thereof.
A composite layer material for dampening external dynamic load, comprising:
- at least a support layer of a resilient material, the support layer having recessed fluid-tight microchannels comprising a fluid, wherein the microchannel section and fluid viscosity dampens the external dynamic load by constricted fluid flow through the microchannels, wherein the resilient material is an agglomerated material.
