I did the same thing with Hex shaped tiles. The only failure I had was if I hit the seam between two tiles. You need to stagger the seams. |

If the need should exist for some measure of resistance in walls to high speed projectiles-I have heard that building a wall with 2x6 on 16 inch centers and covering the bottom 4 feet with 3/4 plywood will allow filling the voids with washed and screened rock of about 3/8 diameter and significantly decrease the possibility of said projectiles penetrating-I have heard of course.

You know, I've seen that video before but I didn't notice till now that that dude looks a lot like me. He's probably 100 lbs heavier but I'm bald and fat. They say the camera makes you look fatter.... maybe I just got roarin' drunk and can't remember.

This could be a cheap, easy solution to catching spall with steel plates, esp. at less than $1 per tile. If you read through the thread I linked to in my OP, you'll see that several people got good results with just Herculiner for mitigating fragments. It's a long thread but lots of good information and most of the posts regarding test information are accompanied by pics and video so it should be easy enough to scan through it for the important parts. |

Betting we could make a plate that's lighter and acts as its own anti-spalling guard. A simple 4 ply laminate of with two ceramic tiles and two rubber tiles taped together would be a worthwhile experiment. I think trying to make one thick tile with fiberglass embedded in it might be worth while. The fiberglass might not survive firing the clay but if it did it would help stop cracks from propagating and would really strengthen the plate. Fiberglass will survive the firing temp. But this project is about using materials on hand as much as possible. These makeshift plates must be tested at a wide range of speeds. Low speed impacts on some materials (transparency materials) cause worse spalling than high speed impacts to the point that the targets are defeated. If I had a big pile of tiles and roofing tar, fiberglass insulation, wood planks, dry wall, or whatever, I would (over) build barricades with the stuff on hand. Personal, portable protection with ceramic tiles is a problem due to weight, but for a short sprint with only a rifle along they might be just the thing to survive. Otherwise, stay below the sky line. |

I was definitely surprised to see that the plates stopped 10 rounds of .40 S&W even after being hit by four rifle rounds. We all know that pistols are nowhere near as powerful as rifles but this sort of thing always drives that point home for me. |

Excellent Test!
Now add a sheet of kevlar fabric at each layer and on outside, with a sheet of D3O shock absorbing material on internal facing side. The kevlar fabric is not that expensive, but the D3O material is a bit pricey still, however it really absorbs the impact force and spreads it laterally. |
