Abstract
The influence of saw blade microgeometry on the adhesive strength of wood–metal composites
Incoming article date: 18.11.2025This article examines the influence of used saw blade surface roughness parameters on the load-bearing capacity of adhesive joints in wood-metal composites. Various methods of steel surface preparation, including mechanical and abrasive treatment, are considered. The focus is on establishing a quantitative relationship between metal surface roughness and adhesive joint strength with varying reinforcement depth and adhesive layer composition. Experimental studies were conducted using the Protodyakonov-Teder multifactorial design method. It was found that surface treatment method has a decisive influence on the load-bearing capacity of the joint, and optimal roughness ensures maximum mechanical adhesion between the adhesive and the metal.
