The evil factory boss, played by Andrew Lancel, attacks and rapes Carla when she ends their relationship on the night before their wedding.
As seen in the newly-released picture below, Frank will pin Carla (Alison King) against the door of her flat when she asks him to leave. However, the actual rape will not be shown on screen.
Later, when the scene cuts back to the flat, viewers will see a broken and terrified Carla sobbing on the floor with Frank standing over her.
A Coronation Street spokesperson commented: "While we don't see the actual attack on Carla, the viewer is left in no doubt about what Frank has done to her. These are powerful scenes which tackle a very difficult subject in a sensitive and moving way."
In the aftermath of the attack, Frank is shocked by his own actions and runs off into the night, while a traumatised Carla phones Maria Connor (Samia Smith) for help - knowing that she was a victim of Frank's unwanted advances earlier this year.
As the week continues, Carla will have to relive her ordeal as she reports the rape to specially trained officers and rape counsellors.
Coronation Street bosses have researched the storyline with experts from the St. Mary's Sexual Assault Referral Centre in Manchester.
Alison King said of the upcoming scenes: "As an actress, it's different to anything I've done before. I've had to go to a few dark places with this plot which has been a real challenge."
Andrew Lancel added: "These have been some of the most challenging scenes I have ever had to play. Frank is an absolute monster but a great character to play - that said, the scenes following the attack were very difficult, it was very heavy stuff.
"I found it very hard. I didn't want to talk to anyone and I was really snappy. We owed it to victims of this sort of attack to get it right and we made sure we researched it thoroughly."
Coronation Street's dark Carla and Frank storyline begins on Monday at 7.30pm on ITV1.
