im 20 years old (born in 1990) titanium is fairly light compared to metall, so i thought i would the best material to build the suit in, but im also thinking about a carbon fiber shell with multiple layers of kevlar inside, what do you think?
Titanium IS a metal. And while it is relatively light, it still has a density of 4.5 g/cm³, which means that one litre of material weighs 4.5 kg. As I said earlier, that's probably not enough, so lets make it 10 kg. In addition to that, you need an undersuit, boots, weapon and possibly you'll have a bag, pocket or backpack with a snack or something. That means in total we're looking at a weight of maybe 15 to 20 kg. That's a lot to carry around, unless you do something like that for a living.
You can use aramide fibres instead of fibreglass, but they're harder to work with, need special tools to cut, are way more expensive and they make no difference in the end whatsoever. They're not even visible. And, if I may add, your costume won't provide any real protection regardless of which material you use. The problem here is not possibility, but making sure it really works.
my intent is that its gonna look AWESOME! no, but seriously. it may be a waste to you guys, but its not really you're money either, is it? i honestly have no idea why people is so conserned about what other chooses to spend they're money on.
It's not going to look any different than a plastic suit. It'll just feel and maybe sound different.
You DID ask what we thought, and "cool, but over the top" seems to be the genereal consensus here, even if it is not what you were hoping for.
that was my intent... but im wondering how im gonna get the ''shade'' effect... like when the helmet goes from a clear visor to a dark one.
It's been done before, with a tinted visor and a light on the inside. Have a look at this:
