David367th I think you missed hafnium carbide. :P They're all amazingly bad though, wow. I thought they'd be comparable to the titanium aluminides. Also considering the performance of PTFE, could you test my PVDF mod?

Also considering the performance of PTFE, could you test my PVDF mod? Shit, added that now. I haven't seen a good ceramic yet, but I'm hoping something will atleast be mediocre. I'll also add that, but again I probably won't get around to mods untill later this week. Also welcome to Godhood Rocket Witch  |

This is very useful data, keep it up!

Quite surprised about selenium and lithium effectiveness against laser in term of cost, but unfortunately they're a bit too heavy  |

Rocket Witch You're mods are done and I'm happy to announce, they're pretty ungodly. The Carbon is particularly weird, usually materials that have good ablation rates share some physical similarities when ablated. Which happens to be dull red sparks and no discoloration/heating of the armor layer. However, the RVS layer both had bright brilliant white/yellow sparks, and the layer heated significantly. That's usually what materials that ablate instantly do, so you may want to look into that.

The brilliant sparks are probably because the ablating material is at 3900 K rather than the far dimmer 1500 k and 500 k of most plastics and fibers. |

RVC basically combines an ultra high melting point with the low density and conductivity which cause low ablation rates. I don't think there's anything I can do about it; foam type materials just seem to be this way in CDE. The laser damage model is weird. The brilliant sparks are probably because the ablating material is at 3900 K rather than the far dimmer 1500 k and 500 k of most plastics and fibers. Ah now that explains a few things, like some materials not producing sparks at all, and a screenshot I've seen of a KKV producing blue-hot sparks in a probably modded game: steamcommunity.com/sharedfiles/filedetails/?id=917586410 |

Is there a common denominator between the armoring attempts? it does seem that both cost and weight varies quite a bit, are they chosen as common thickness people use or something like that?

I was wondering how Aluminum and Molybdenum held up. Both being highly reflective materials(I am aware reflectivity is less useful than other factors when armoring against lasers though).

I was wondering how Aluminum and Molybdenum held up. Both being highly reflective materials(I am aware reflectivity is less useful than other factors when armoring against lasers though). From past tests, both proved to be very ineffective. This is probably due to the fact that their extremely high reflectivity decreases as their temperature increases. Yet, it won't hurt to throw them into the pile. Is there a common denominator between the armoring attempts? it does seem that both cost and weight varies quite a bit, are they chosen as common thickness people use or something like that? Generally yes, there is a standard. Every armor originally was to be in equal mass to that of 100cm/1m of Silica Aerogel. Which was a common material that people had used months ago, then eventually the gels resistance was corrected in a patch. If their mass varies, they may be using a standard thickness or if they're a predetermined composite they use the specifications provided. The brilliant sparks are probably because the ablating material is at 3900 K rather than the far dimmer 1500 k and 500 k of most plastics and fibers. Ah now that explains a few things, like some materials not producing sparks at all, and a screenshot I've seen of a KKV producing blue-hot sparks in a probably modded game: steamcommunity.com/sharedfiles/filedetails/?id=917586410Actually it seems that most materials have the same unique color regardless of temperature. Such as Silver producing bright green sparks. It may have been that the armor used on either craft was either modded, or a hafnia/samarium armor layer. |

Put 500µm in front of ≥1cm of diamond and ostensibly the reflective material can do its thing while the diamond sucks the heat away from it. David367th please consider that something to test under composites. Also I would like to request a test for carbon fiber: childrenofadeadearth.boards.net/thread/1429As for green sparks, huh... if that's the case, RVC should produce the same colour sparks as amorphous carbon, graphite, and anything else with 1C as its only constituent element. |

Alright, I should be able to get all of them done by tonight (10 EDT ish for those not murican) soon. Aluminum and Molybdenum both been added to original, Carbon Fiber in modded, and two Heatsunk Mirrors one for 1cm diamond and another with 5cm diamond. Rocket Witch if you want a better name let me know of course. |
