Upgrade NowYou can vapor deposit chrome to anything, or you can probably use an electrodeless nickel chrome plating process, but it will not do what you want it to.You know I was thinking. You know how for the auto industry they chrome plate auto parts like bumpers and such. I dont know anything about chromeing things. My thought was could you actually chrome a composite fin can just like plastic parts are chromed? My thought behind that is the chrome plating can act as a barrier from the heat so consequently protect the composite underneath. IDK What do you think or is it just pie in the sky??

Powder coatings are cured at 200 C (400 F). Most rockets won't take those temperatures.....Chrome plating is a multi-step process.
They start with an acid bath... followed by dipping the item in: Copper then, Nickel, finally Chrome.
Has anyone attempted powder coating a rocket?

At Mach 2.5 the maximum stagnation gas temperature is ~350 C (660F) @ ~ 1 mile AGL under standard conditions (seal level @ 15 C (59 F). The surface temperature will be less. You can simulate the effect with a 1000 F heat gun for ~ 10 s -20 s.Yea I am thinking mach 2.5
What about building the rocket out of sheet aluminum?
Why?What about building the rocket out of sheet aluminum?
Stainless steel sounds heavy. Maybe a really thin wall nosecone (since that's the only part that's going to get heat) could work? Titanium sounds too exotic right now.
Its time to resurrect this build thread. After putting this rocket on the back burner I have decided to put it out of mothballs and try to finish it.
Hey Andrew , I just looked over this thread again . As far as heat protection / ablatives go , just do like the big boys do . They take high temp red rtv , thinned down with acetone. Paint it on , let cure and fly .

It is as simple as it sounds . You thin the RTV down just enough to apply with a HVLP sprayer. The idea is that the RTV WILL burn off and carry the heat with it during the critical time the rocket is accelerating thru M3+ at lower altitudes . The solution to the higher CD rate of the rocket while the rtv was burning off was solved by using more thrust.

What do u guys think will be better. A filament wound ogive cone from rocketry warehouse or a new fiberglass poly infused pheonlic tip cone from Wildman?
IMO, stick with the same manufacture of the tubing you used.
I agree with you on that part. But would I gain a better advantage on going with that cone from Wildman over a filament wound from rocketry warehouse?
