The Response of Screw Corner Joints Manufactured of Honeycomb Panels to Changes in Relative Air Humidity
Year: 2025
Type: conference-paper
Abstract: Honeycomb panels are an attractive material for furniture production.However, their usefulness in industrial practice depends on the technological quality of corner joints and the effect of temperature and relative humidity changes on the stiffness and strength of these joints.This work made corner joints from 37 mm thick honeycomb panels.A screw confirmat type was used for the connection.It was experimentally determined to what extent a change in air relative humidity from 40% to 85% will affect the strength and stiffness of corner joints.Numerical models were developed to predict the behavior of joints in variable climatic conditions.It was shown that an increase in air humidity reduces the stiffness and strength of joints.However, in conditions of extreme humidity of 85%, the stiffness and strength of joints are still acceptable compared to dry conditions (40%).Numerical models allow for correct estimation of the quality of joints.
