The experimental study results of the of the carbon/epoxy laminated curved beams strength of samples based on laminated carbon fiber and laminated carbon fiber reinforced in the transverse direction by Tufting firmware with four-point bending are presented. We obtained loading diagrams and diagrams of the dependence of the cumulative energy values of acoustic emission signals for layered samples and layered samples reinforced with transverse piercing. The tests were carried out according to the procedure agreed upon with the international standard ASTM D6415 with using the electromechanical system Instron 5965 and the acoustic emission signal recording system AMSY-6.
