In 1972 the Faculties of Chemistry and Biology were founded. At the same time the Faculty of Technology was split into the Faculties of Mechanical Engineering and Electrotechnology, Architecture/Regional and Environmental Planning/Educational Sciences.

In 1975 the twin university was split into two independent universities: The University of Trier and the University of Kaiserslautern. The Faculties, which were established successively, continuously strengthened the university's scientific character: Electrotechnology (1975), later Electrical and Computer Engineering (1999), Computer Science (1975), Engineering (1975), later Mechanical and Process Engineering (1995), Architecture/Regional and Environmental Planning/Civil Engineering (1978–1979) and Social and Economic Studies (1985). The official name of the University is Technische Universität Kaiserslautern according to the new law on Higher Education of the Land Rhineland Palatinate which came into force on September 1, 2003.
