摘要:The paper presents the results of the compression tests for carbon-epoxy composites in order to assess theamount of energy absorbed depending on the process velocity and content of axial fbres. Two types of prepreg(UD 200 g/m2 and woven 160 g/m2) were used to prepare the specimens with a diameter of 20 mm and a heightof 34 mm. The specimens were subjected to compression under various speed conditions (static, dynamic andSHPB tests). The calculated specifc energy absorption values showed a 50–60% decrease with increasing process velocity and depending on the type of specimens architecture. The highest energy values were absorbed bythe specimens with the highest share of axial fbres in the sample.
