I've heard that Barricade died in the novel "The Veiled Threat" - not entirely sure as I haven't read it myself. Novel spoiler ahead





From TFwiki:
"Prime and the Autobots enter the (Coliseum), and Prime promptly falls through a trap door to a subway tunnel extension and into a strong set of restraints arranged by Carrera. Starscream then proceeds to attack the remaining Autobots while a helpless Prime is confronted by a vengeful Barricade. Before the Decepticon can dispatch Prime, the humans attack Barricade and Prime manages to work himself free. He easily hands Barricade his skid plate and returns to the surface where Starscream has fled."
