Abstract
An impact dissipating material comprises a matrix material defining a plurality of cells and an interpenetrating material carried by the matrix material. The interpenetrating material is disposed in a first position relative to the plurality of cells of the matrix material under a first loading condition and in a second position relative to the plurality of cells under a second loading condition. The combination of the matrix material and the interpenetrating material defines the overall impact response of the impact dissipating material.
Claims20
An impact dissipating material, comprising:
- a matrix material defining a plurality of cells;
- and
- an interpenetrating material carried by the matrix material, the interpenetrating material disposed in a first position relative to the plurality of cells of the matrix material under a first loading condition and in a second position relative to the plurality of cells under a second loading condition.
An impact dissipation system, comprising:
- a base;
- and
- an impact dissipating material carried by the base, the impact dissipating material comprising:
- a matrix material defining a plurality of cells;
- and
- an interpenetrating material carried by the matrix material, the interpenetrating material disposed in a first position relative to the plurality of cells of the matrix material under a first loading condition and in a second position relative to the plurality of cells under a second loading condition.
A method of manufacturing an impact dissipating material while preserving a wall structure defining each cell of a matrix material, comprising:
- fluidizing an interpenetrating material to reduce a viscosity of the interpenetrating material from a first viscosity value to a second viscosity value;
- applying the interpenetrating material to the matrix material;
- and
- adjusting the viscosity of the interpenetrating material from the second viscosity value to the first viscosity value.
