Claims
- 1. A filamentary three-dimensional material comprising:
- a. a group of filaments oriented substantially parallel to each other on a Z axis in two groups of intersecting rows defining an X axis and a Y axis;
- b. a second group of filaments woven on said X axis extending through said oriented filaments in courses which are at an angle to said Z axis;
- c. a third group of filaments woven on said Y axis extending through said oriented filaments in course contiguous with said X axis courses; and
- d. said filaments being sized and spaced relative to each other such that the filaments on each axis are compressed into close frictional contact with the adjacent filaments on each other axis to bind said material into an integral structure having a density of at least 30% of the density of said filaments.
- 2. A filamentary three-dimensional material as claimed in claim 1, further comprising a hardened matrix substance impregnated into said filaments and filling the voids between said filaments.
- 3. A filamentary three-dimensional material as claimed in claim 1 in which said filaments woven on the Y axis form a helix extending along the X axis.
