The Marussia drivers came together at turn three when Chilton seemed to lose control of his car and slide into Bianchi. That triggered a heavy impact with the wall for the Frenchman and caused significant damage to his car. Both men were eliminated on the spot.
Chilton was later handed a three-place grid penalty for the Austrian Grand Prix, but was unwilling to accept blame for the collision.
"We were side-by-side into turn three and I was half down the inside and I braked at point where I knew I could get around corner," Chilton told reporters afterwards.
"He [Bianchi] braked later - and he was only in front of me because he braked so late. There was nothing I could have done.
"I am not going to back off down the inside because he is my team-mate, he should have seen me."
In a post-race statement, Bianchi stopped short of blaming his team-mate.
“I got a great start, kept everyone who was behind me behind and then obviously Max and I were racing each other through turns two and three," explained the Frenchman.
"I braked into turn three and there was an impact, after which I ended up in the wall with a badly damaged car."
