CO~lPOSIq~E CERAMIC AR2tOR
ANn NlSTHOD FOR ~ING SA1~15 TECHNICAL FIELD
This invention relates to composite ceramic armor and to a method for making the armor.
BACRGROUND ART
Prior art armor has utilized plate-like ceramic tiles embedded in a matrix to provide protection against incoming projectiles. See, for example, U.S.
Patents: 3,324,768 Eichelberger; 3,431,818 King;
3,444,033 King; 3,509,833 Cook; 3,516,898 Cook;

Other non-armor prior art noted during the investigation conducted in connection with the present invention includes U.S. Patents 3,232,017 Prusinski et al and 4,049,864 Hoover et al.
DISCLO5URE OF INVENTIO~
An object of the present invention is to provide improved composite ceramic armor and a method for making the armor so as to provide relatively light-weight protection that is economical to manufacture and capable of being utilized to fabricate larger surfaces as well as being easily repairable.
In carrying out the above and other objects of the invention, composite ceramic armor constructed in accordance with the present invention includes a plural-ity of plate-shaped ceramic tiles each of which has oppositely facing surfaces and a plurality of sides.
Cloth is wrapped around each tile over each surface and side thereof in the fabrication of the armor. A syn-thetic resin matrix permeates the cloth to encapsulate the tiles. ~his resin matrix defines oppositely facing surfaces and a plurality of sides with the wrapped cloth spacing the tiles from each other and from the surfaces and sides of the resin matrix.
In its preferred construction, the tiles are rectangular and the cloth includes a pair of strips wrapped around each tile in perpendicular directions to each other. As disclosed, the rectangular tiles are square.
In the preferred construction, the cloth utilized is woven and is most preferably made from glass fibers or polyamide plastic fibers such as Kevlar.
A method for making composite ceramic armor in accordance with the present invention comprises wrapping plate-shaped ceramic tiles, each of which has oppositely facing surfaces and a plurality of sides, with cloth that extends over each surface and side of each tile.
The wrapped tiles are then placed in a mold cavity with the wrapped cloth spacing the tiles from each and from a mold wall defining the cavity. A synthetic resin is then introduced into the mold cavity to permeate the cloth and provide a matrix that encapsulates the tiles and defines oppositely facing surfaces and sides from which the tiles are spaced by the wrapped cloth.
In the preferred practice of the method, rectangular tiles are utilized and each is wrapped by cloth including two strips that extend perpendicular to each other around the tile. The rectangular tiles are disclosed as being square.

BE8T MODE FOR CARR~ING_OUT T~E INVENTION
As illustrated in Figures 1 and 2, composite ceramic armor constructed in accordance with the present invention is generally indicated by 10 and includes a plurality of plate-shaped ceramic tiles 12 each of which has oppositely facing surfaces 14 and a plurality of sides 16. Cloth 18 best illustrated in Figure 2 is wrapped around each tile 12 over each surface 14 and side 16 of the tile. A synthetic resin matrix 20 1 3 1 ~733 permeates the cloth 18 to encapsulate the tiles 12 as is hereinafter more fully described. This resin matrix 20 defines oppositely facing surfaces 22 and a plurality of sides 24. The wrapped cloth 18 spaces the tiles 12 from each other and from the surfaces 22 and sides 24 of the resin matrix 20.
The ceramic tiles 12 of the composite ceramic armor 10 illustrated in Figures 1 and 2 are spaced from each other sufficiently far so that shock generated by an impacting projectile will not propagate from one tile to the next while still being sufficiently close to each other so that the projectile to be defeated cannot penetrate between the tiles.
As illustrated in Figure l, the ceramic tiles 12 are preferably rectangular and are disclosed as having a square construction that facilitates fabrica-tion of the composite armor with a square construction for incorporation into larger panels. Depending upon the panel shape needed, elongated rectangular tiles can also be used for fabrication into larger panels. Such larger panels provide larger surfaces that can be easily repaired by replacement of a panel having one or more tiles that fracture upon stopping a projectile.
As illustrated in Figures 3, 4 and 5, the cloth 18 preferably includes a pair of cloth strips 26 and 28 wrapped around each tile in perpendicular direc-tions to each other. More specifically, the first cloth strip 26 is wrapped around the ceramic tile 12 as illustrated in Figure 3 in a first direction and, as shown in Figure 4, is wrapped a plurality of times to provide the desired spacing which is provided by three turns in the specific embodiment illustrated. The second cloth strip 28 is wrapped around the first cloth strip 26 in a perpendicular direction thereto as shown in Figures 4 and 5. This second cloth strip 28 is also wrapped a plurality of times to provide the required spacing which, in the illustrated embodiment, is three turns. Both cloth strips 26 and 28 have a width equal to the length of the sides 16 of the tile 12 such that the wrapped tile is completely covered without using any unnecessary cloth. Such wrapping can also be done with lo elongated rectangular shapes with cloth strips of different widths each to the side lengths of the elon-gated rectangular tile.
As illustrated in Figures 3, 4 and 5, the cloth 18 is preferably woven and includes perpendicular rovings 30 and 32 which can be made from various materi-als but are most preferably made from glass fibers so as to be economical while still having the ability to maintain integrity for most types of synthetic resins utilized for the matrix 20. Plastic fibers can also be used, preferably fibers of polyamide plastic such as Kevlar fibers.
It is preferable to utilize a thermosetting synthetic resin for the matrix 20 such as a polyester or epoxy so that the armor will maintain structural integ-rity even when heated. Also, while a single layer ofthe cloth wrapped ceramic tiles 12 is disclosed, it is also possible to use two or more layers of the tiles with the spacing between the tiles either aligned or staggered.
The method for making the composite ceramic armor 10 illustrated in Figures 1 and 2 is performed by first wrapping the plate-shaped ceramic tiles 12 previ-ously described with the cloth 18 that extends over each surface 14 and side 16 of the tile. These wrapped tiles are then placed as illustrated in Figure 6 in a mold cavity 34 of a mold 36 such that the wrapped cloth 18 spaces the tiles from each other and from a mold wall 38 that defines the cavity 34. A liquid synthetic resin is then introduced through an inlet 40 of the mold 34 to permeate the wrapped cloth 18 prior to hardening that provides the matrix 20 which encapsulates ~he tiles 12 lo and defines the oppositely facing surfaces 22 and sides 24 from which the tiles are spaced by the wrapped cloth.
A bleed port 42 permits excessive synthetic resin to bleed out of the mold cavity 34.
It should be noted that the mold 36 illus-trated has a lower plate 44, side plates 46 and a top plate 48. The lower plate 44 has recesses 50 that receive the lower ends of the side plates 46, and these recesses 50 also have seal recesses for receiving seals 52 that are most preferably constructed as double-sided foam tape for securing the side plates in position within the recesses 50. The top plate 48 is removable to permit the introduction of the wrapped ceramic tiles into the mold cavity and to also permit removal of the molded composite ceramic armor 10. A suitable schemati-cally illustrated clamp 54 is utilized to hold the topplate 48 in position with a peripheral seal 56 extending along the upper end of the side plates 46 within re-cesses therein and within a recess in the top plate in order to provide a sealed relationship.
The method for manufacturing the composite ceramic armor most preferably utilizes rectangular tiles that are each wrapped by cloth including two strips that extend perpendicular to each other around the tile as previously described. Square tiles, as also previously mentioned, may be utilized to produce square composite ceramic armor that is easily constructed into larger panels. Elongated rectangular tiles can also be used.
It should be noted that the tiles can be wrapped with cloth by either a manual operation or an automated machine operation.
Woven cloth is also preferably utilized in the method to wrap the tiles as previously described and is advantageously made from woven glass fibers as was also earlier mentioned. Woven plastic fibers can also be used, preferably polyamide plastic fibers such as Xevlar fibers.
While the best mode for practicing the inven-tion has been described in detail, those familiar with the art to which this invention relates will recognize various alternative ways of practicing the invention as defined by the following claims.
