We study possible strong first-order electroweak phase transitions inComposite Higgs models and we quantify the part of parameter space that can beprobed with future gravitational Wave experiments. We focus on models where theComposite Higgs sector arises from underlying four-dimensional stronglyinteracting gauge theories with fermions, and where the Standard Model fermionmasses are induced via linear mixing terms with composite fermions -- theso-called fermion partial compositeness framework. We perform our analysis forthe general class of Composite Higgs models arising from $ N $ Weyl fermions ina pseudo-real representation of the new strongly interacting gauge group thatdynamically triggers the global chiral symmetry breaking pattern$\rm{SU(}$$N$$\rm{)}\rightarrow \rm{Sp(}$$N$$\rm{)}$. The minimal model has $N=4 $ and for $ N>4 $ the models feature complex scalar dark matter candidatesarising as pseudo-Nambu-Goldstone bosons. We find a large number of points inthe models parameter space which yield strong first-order electrowea}$k phasetransitions and identify the most important operators characterizing thestrength of the phase transition. Almost all of these points are testable withfuture GW detectors such as LISA, Taiji, Tianqin, BBO, DECIGO andUltimate-DECIGO.
