Another idea is that the stab actually has no real effect on Iron Man because he is not really there. It could be an illusion created by Doctor Strange to deceive Thanos. Iron Man could be on another planet or in a hidden location, and Thanos falls for the trick, thinking he has finally defeated one of his greatest enemies.
Perhaps Thanos stabs Iron Man, but it's part of a bigger plan by Iron Man himself. He could have anticipated Thanos' move and allowed himself to be stabbed in order to get close enough to Thanos to plant a powerful device. This device might be something that could disable Thanos' powers or even send him to another dimension.
The Avengers would likely be filled with rage. Captain America, for instance, would immediately charge at Thanos, not caring about the danger. His sense of justice and loyalty to his friend would drive him to seek revenge right away.
One interesting plot twist could be that Iron Man discovers a hidden power within his suit that can counter the Infinity Stones. Maybe it was something he unknowingly built into it long ago.
Yes, Iron Man was killed by Thanos. The scene was intense and left a lasting impression. It was a turning point in the comic's narrative and led to various consequences for the other characters.
Thanos could also win in a fanfiction. He has incredible strength and the power of the Infinity Stones at his disposal. In a lot of fanfictions, the power levels are often exaggerated. Thanos could simply use the Reality Stone to make Iron Man's weapons ineffective or use the Time Stone to freeze Iron Man in time and then defeat him. His brute strength alone is enough to overpower Iron Man in a direct confrontation. And his experience in battles across the universe gives him an advantage over Iron Man who mainly operates on Earth.
