Quoted: What are the comparative advantages/disadvantages between two III+ plates, one PE-only and the other a PE/ceramic composite? Tomac |

Ceramic/PE hybrid tends to be a much better all-around balance of weight vs stopping realistic rifle rounds at realistic velocities.
The whole idea of ceramic armor is that by cracking on impact, it also induces cracking in the impacting projectile. Then the PE slows down and catches whatever degraded objects get through the ceramic front layer. Pure PE plates will tend to be a lot lighter, but the ceramic/PE hybrid plates still aren't that heavy. Get ceramic/PE. |

I believe the combo plates offer a slight improvement in thinness/bulk over pure PE plates, which is one of their main drawbacks.

The PE-only III+ plate is slightly heavier than the III+ PE/ceramic and is supposedly rated to stop M855, still good against M855?
Tomac ETA: While not on their website, this search engine info was shown w/the link to the III+ PE, apparently there *is* ceramic in the 'PE-only" III+ plates: "Made w/Ultra High Molecular Weight Polyethylene Fabrics & CERAMIC Tested to NIJ Level III+ / NIJ-0101.06 Multi-Hit Capability will defeat M855 5.56mm 62gr, 7.62x39 12gr Ball Fully Sealed - Corrosion Protection, Structural enhancement, Waterproof..." |

Is there a PE only plate rated for III+? I thought they were all ceramic.

Quote HistoryQuoted: Is there a PE only plate rated for III+? I thought they were all ceramic. There are some people who try and pass off the additional threat of M193 as a "III+" with M855 being a "III++". I think this is BS marketing and anyone who isn't a sham will go with the industry de-facto standard of calling M855/penetrator capable plates as III+ But to answer your question, no full PE plate will be able to stop penetrators and will need a hybrid ceramic/PE design. |

OK, that's what I thought. When the new .07 standards are in use eveywhere it should make this more clear. Those PE plates aren't gonna meet RF2. |

For plates, the rule is ABC:
Always Buy Ceramic |

I contacted BS's/Botach's supplier of the armor. The single curve III plate is SIC and 10mm of PE, and tile array. The multicurve III+ is SIC solid strike face with 12mm of PE

I’m assuming you are referring to shot stops duritium plates that say they stop “62gr ball”? |

I think pure PE plates are also buoyant, which if it’s a consideration could be pretty important.

Quote HistoryQuoted: Tile plates have shown to handle threats just fine. SIC from my testing degrades a LOT faster than Alumina, so if you can use tiles to keep cracking from propagating, I don't see them as a negative. the extra 2mm of backer is a + though @Buffman_LT1 Let me rephrase: A 4lb 9oz tile ceramic/PE single-curve III+ plate w/10mm PE backing vs a 5lb solid face ceramic/PE multicurve III+ plate w/12mm PE backing. Any significant reason to choose one over the other? Thx again! Tomac |

If they were both multicurve id go for the lighter one. The multi curve ones might feel lighter anyways

Multi curve.
You can train for a few ounces of weight, but that single curve is always going to ride awkward and dig in to your back. |
