Sorry to rain on your parade , but if your planning to make a Ironman suit " bullet proof" , then you need to take into account the armour thickness and the required padding , moulding kevlar is not the same as laying fibreglass , one mistake and 'Bang' your dead !! The massive overriding factor is weight, and the physics involved and how are you going to move in the suit? As I have said on other forum posts , you cannot make a real Iron man suit, it's just not practical , make an Iron man suit of real steel first, and see how you go, as that will be like making a suit of armour,anyway - your target weight for the suit is 65 lbs total weight, as that is the average weight of a suit of armour from the 12 to 14th Century.
is possible, I show you the bullet-proof 'custard', or the Liquid Armor; It is a non-Newtonian dilatant fluid, works by absorbing the force of impact of the bullet and responds by becoming more viscous. the molecules are joined together when there is a collision.. It is liquid under low or normal pressure and solid under high pressure. This liquid is made with polyethylene glycol and the solid part is made of nano-particles of silica. This liquid is soaked into all the layers of a Kevlar vest.
The suit works using a viscous compound which, when attached to traditional Kevlar, absorbs the force of a bullet and responds by becoming thicker.
The pioneering technology has been created by a team of scientists at the global defence and security company BAE systems in Filton, Bristol.
This new fluid moves like a liquid until it hits a hard object in a few milliseconds and the fluid harden. The fluid is a colloid, ie physical-chemical system consisting of two phases continuous, normally fluid, and other dispersed as solid particles usually. The particles repel each other, but the energy of a sudden impact fills the repulsive forces between the particles and come together to form lumps called hydroclusters. When the impact energy is dissipated, the particles start to repel again returning to its initial state.
Is no cheap, and we are talking about do something real and functional, life is no a movie, in my proyect I go to use aluminium 6061, is no expensive and is a good material for work, specialy soldering if I need do it, so good luck with your proyect, but really think in real mode, If u gonna do something, do it well, if no, don´t do it.
