It forms a foundation for designing tools for bending and determines the stress that products and their parts can be exposed to during use. This study analyzes the effects of selected factors on the selected characteristics, such as the coefficients of wood bendability (<i>K</i><sub>bendC</sub> and <i>K</i><sub>bendB</sub>). The selected factors of this study were wood species (WS) (<i>Fagus sylvatica</i> L. and <i>Populus tremula</i> L.), non-wood component (carbon fiber and glass fiber), position of the non-wood component in the laminated material (top and bottom), material thickness (<i>T</i>) (6 mm, 10 mm, and 18 mm), and adhesive (polyvinyl acetate and polyurethane), as well as their combined interaction on the monitored characteristics described above. The results contribute to the advancement of knowledge necessary for the study and development of new materials with specific properties for their intended use. The measured values of laminated structures can be compared with the values measured on the samples from the wood. The results can improve the innovative potential of wood processing companies and increase their performance and competitiveness in the market.https://www.mdpi.com/1999-4907/10/6/470coefficient of wood bendabilitylaminated woodtechnological and product innovationsminimal curve radius |

Knowledge of the coefficients of wood bendability (<i>K</i><sub>bendC</sub> and <i>K</i><sub>bendB</sub>) and of the effects of selected factors on the listed characteristics in bending stress has both scientific and practical significance. It forms a foundation for designing tools for bending and determines the stress that products and their parts can be exposed to during use. This study analyzes the effects of selected factors on the selected characteristics, such as the coefficients of wood bendability (<i>K</i><sub>bendC</sub> and <i>K</i><sub>bendB</sub>).
