Fig. 2 (a) Integration of the carbon fiber tow as electrical contact before filament winding procedure; (b) Specimen for flexural loading after manufacturing; (c) Configuration of electrical resistance measurement during flexural test; (d) Configuration of electrical resistance measurement during torsional test. Detailed description of composite layers is given in Kropik et al 2022. Specimens for bending test were manufactured as one half of specimens for torsional tests, see Fig. 1 and Fig. 2. 2.2. Electrical contact preparation Electrical contacts were prepared from a carbon fiber tow ex-PAN T300 ((Toray Composite Materials America, Inc., USA). Carbon fiber tow was cut in the length of 310 mm and 150 mm in order to compare manipulability during specimen manufacturing, the circumference of the cross section of the specimens was 160 mm.
