Abstract
CDF dijet data have been analyzed to search for evidence for quark substructure in the angular distributions. The data consist of 11,903,325 events obtained with the single jet E_T>100 GeV trigger, and an integrated luminosity of 1109 pb-1. No evidence for quark substructure was found, and a limit on the coupling parameter Lambda>2.4 TeV 95% confidence was obtained. Systematic uncertainties dominate the limit.
