Thats the armor i use for ships.
It is (was) highly secret so don't use it on your ship or i will find you solar system and nuke it until all life in it goes extinct.
Diamond and amorphous carbon are for laser. Diamond graphitizises at 1600 K but can spread the heat fast enough for weak and medium lasers. They're also my whipple. If something penetrates that diamond layer. Usually light railgun rounds ricochet off of it as my sheeps have steep noses.
That graphite areogel slows down plasma, wich impacts on CFRC.
Heat is insulated from the boron filament layer by the amorphous carbon, wich should stop things that didn't become plasma after the whipple.
The EP rubber is the least dense of the rubbers and cheaper also. Anti-spalling?
It is cheap and light yet strong
Tell me if you think something could be improved, or if i misunderstood something.

You might wish to replace the Ethylene Propylene Rubber with either Boron Filament or Spider Silk. I recommend you replace the Reinforced Carbon-Carbon with Amorphous Carbon. It's stronger and less expensive.

Set Whipple shield larger than 1 meter does not contribute much to defence than 1 meter.

Diamond is a poor anti-laser armor due to its high heat conductivity and transparency. PE is the best you can do in vanilla where ablation cap decides laser performance. With the cap modded out, a-carbon is most effective at absorbing heat.
Heat conduction or armor cooling down is not modeled, so thinking about them isn't helpful.

It's stronger and less expensive. As I already have boron filament i would go with spider silk. But why spider silk instead of rubber? I don't understand why nasa uses CFRC instead of amorphous carbon then... Thought i was never satisfied by it, but never thought about replacin it with AC. Also, why default ships use CFRC instead of AC? |

Uhm you first said that diamond is a poor anti-laser armor due to it's high heat conductivity and the said that heat conduction isn't modeled into the game... I'm confused... Is diamond transparent to infrared? Why would it's heat conductivity be bad against a laser? (It would help spread heat in a larger area so that AC can absorb more of it). What is PE? What is ablation cap? |

Thanks everyone for replying. Please, if you think i could change something, tell me and EXPLAIN why i should.
P.S. Why is diamond black in game?

Is diamond transparent to infrared? Why would it's heat conductivity be bad against a laser? (It would help spread heat in a larger area so that AC can absorb more of it). What is PE? What is ablation cap? The game has a very simplistic model of laser ablation where the laser penetration depth is decided by its thermal diffusivity or transparency, whichever allows higher penetration. Ablation is applied the instant a laser hits and there's no long-term simulation of heat transport mechanics. This means that every material has a point after which increasing laser intensity no longer affects the amount of ablated material, usually called the material's ablation cap. Diamond is both an excellent conductor and transparent, meaning its ablation cap is in the range of several gigawatts per square meter. Polyethylene (PE) is the material with the best ratio of ablation cap to cost and mass, with a maximum intensity of just 4 MW/sq. m. That's why it makes the most effective anti-laser armor. Other options are Aramid Fiber, with the best mass and thickness efficiency, and Selenium, which has the best performance per credit. |

The game doesn't model what things look like through other layers of stuff, so as a result, diamond (and to a lesser extent, water, or ice, also) comes out black. |

Would diamond-amophous carbon be a good anti-laser armor in real life? |

Diamond might have issues as it turns into the less dense graphite at around 1800-1900 K AFAIK. This would cause cracking. With the ablation cap removed, amorphous carbon is hands-down the best anti-laser armor, and it's also pretty good as anti-kinetic armor. So it tends to be included in all my armor schemes, even though I usually don't go for much armor. |

I was thinking that Diamond would rapidly transfer the heat to more diamond, increasing the area in wich the heat is transferred to the AC, wich having an higher specific heat would take the major part of it. Maybe this wouldn't work as diamond is transparent. Would it really crack because of graphitization? I mean, after all it's diamond vs graphite, probably the graphite would detach from the armor instead. An advantage of 0.25mm Diamond - 0.75 AC is that while the AC makes for a decent kinetic armor, diamond makes the surface of the armor really hard. At steep angles diamond is able to make light projectiles ricochet without a scratch. So if diamond doesn't turn out to be bad against lasers that would make the perfect armor. If diamond doesn't compromise the effectivity of the armor against laser i think i will keep it anyway for a protection against light projectiles. As i go for realism i will also keep AC as a laser armor. |

Do I really need an anti-spalling layer if the armor is itself boron filament?
Why even thinking about reinforced carbon-carbon if amorphous carbon has higher specific heat and is stronger? Why do default ships use it? CFRC is weaker than AC but is also less dense. What has the highest strength/density ratio between the two?

You don't necessarily need an anti spall layer, but if youre getting hit by a nuke, or a large enough conventional HE payload, you're going to regret not having one. Reinforced Carbon is used commercially in actual space stations, including the ISS. Default ships use this because they're stock ships, not hyper optimized like most of our ships. To be honest, ACC is a bit of a nebulous material. I presume it's just linked together carbon atoms, but I don't really get it. |
