A British building material manufacturer has won a $36 million verdict in its federal breach of contract case against Zoltek Corporation, a St. Louis-based carbon fiber manufacturer.
In its lawsuit filed in U.S. District Court, Eastern District of Missouri, Structural Polymer Systems, Ltd. claimed that Zoltek quit supplying its requirements for large filament count carbon fiber in breach of a 10-year supply contract signed in 2000. But Zoltek maintained that the contract covered only an earlier version of the product SP Systems had ordered through 2003, not an improved version launched in 2004.
