Composite models, which suggest a possible substructure of fundamental
particles, can be directly proven by the discovery of the excited quark.
Higher energy and higher-luminosity particle colliders are needed to
discover the composite structure predicted in the proposed models. The
High Energy Large Hadron Collider (HE-LHC) has the potential to be a
possible discovery machine for composite models. In this collider, with a
center-of-mass energy of 27 TeV and integrated luminosity between 750
and 15000 fb\textsuperscript{-1}, we calculated the exclusion,
observation, and discovery limits for the mass of spin-1/2 excited quark
in the \textit{di-jet} final state, as well as the attainable
compositeness scale values. In addition to these calculations, we
scanned free parameters from 0.06 to 1 to determine the HE-LHC potential
to reveal spin-1/2 excited quark.
