The aim of the project is to study the impact of some parameters relating to gluing (moisture content, gluing process, open assembly time and assembly time in gluing) on the formation of urea formaldehyde (UF) and urea melamine formaldehyde (UMF) adhesive bond , and the mechanical properties of the latter. Research will focus on the dependence of penetration of UF and UMF with regard to different wood moisture contents. Wood moisture content gradients will be selected on the basis of experience-based moisture content interval as used in the gluing of wood in practice. Also studied will be the influence on the manner of gluing (standard and HF gluing) and on adhesive penetration.. The assessment of the depth of penetration of adhesive will be carried out by a special technique of florescent microscopy and by means of a computer programme designed for qualitative assessment of penetration. By means of multiple range analysis, specific differences regarding the penetration of adhesive as a function of moisture content and the wood gluing process will be determined. Following the analysis and the determination of correlation between the gluing parameters used and adhesive penetration depth in the adhesive bond, by means of correlation analysis, correlation will be sought between adhesive penetration depth and shearing strength of the adhesive bond. In the final stage, research will focus on the development and application of fracture mechanics - a special method of adhesive bond testing (still in the development phase also elsewhere in the world) , which should provide more accurate and reliable testing of the strength of adhesive bond.
