Looking at the materials folks are using, it seems like a lot of them are very high in compressive strength. Although that does play a small part in the role of armor, compressive strength comes into play in a small cone ahead of the projectile.
Shear strength ought to be the desirable trait for kinetic defense outer layers. As the force of the impact deforms and propagates through the material, the resistant to pulling apart controls how far the impactor penetrates. There's a function of KE for the impact event that determines the requisite thickness to prevent penetration.

Been meaning to work this stuff out mathematically for a while.

Is there any armors good agianst lasers and kinetics ?
Its for my turrets, since I can only put on one type of armor ?

Thats the absolute best for cist and weight ?
What about nitrile rubber ? I see so many people using it in there designs these days

Aramid fiber is the most weight-effective anti-laser armor. Silica airogel is the best nukeflash armor. Graphite airogel stuffed double whipple shields are the best kinetic armor. Amorphous carbon is the best general-purpose monolithic armor (but composite armors are better).

The 13MW 3mm Sniper Coilgun is painful.
Sure my armor stops the first 3-4 rounds but that little bugger keeps hitting the same armor panel.

Diamond with an amorphous carbon heatsink backing layer works as a combined laser/kinetic armor.

My current go-to armor on ships around 1,200 tons or less is the following:
5-10mm Spider Silk 4-6cm Amorphous Carbon 25cm Silica Aerogel or ~50cm Graphite Aerogel 5mm Boron
I haven't tested its effectiveness against lasers yet, but it's resistant to light kinetics and flak.

I use a few mm of graphene (modded material). It's lighter than lithium, and stronger than vanadium chromium steel. When combined with some aggressive angling, it allows my ultralight laserstar to survive a few dozen sandcaster rounds. If only my laser turrets where that resilient.

For fun, I reproduced the projectile mass and velocity of a 7.5cm KwK 42 anti-tank gun from WW2. My hull armor can withstand several direct hits, although the same certainly cannot be said of the turrets.

Not really, but it's light and very cheap.
