In composite Higgs models the scalar particles in the Higgs sector are not elementary particles, but of composite nature, arising as pseudo Nambu-Goldstone bosons from higher broken symmetries. In a composite 2-Higgs-Doublet Model thus a 2HDM-like structure is generated but with couplings already predetermined by the composite nature of the model. In this talk we present Higgs Pair production in this model via gluon fusion. We give a brief introduction into the model and an overview over the calculation, highlighting the contributing couplings and diagrams. We apply current experimental limits for Di-Higgs production on our results and study differential distributions for specific benchmark scenarios.
