The principal objective of the research project is to identify the thickness of an advanced
composite adhesive material used as part of a glued connection of wooden surfaces. The active
ingredients of the proposed adhesive material include an epoxy matrix and a glass fiber fabric. The
author has analyzed the bearing capacity and deformability of the proposed connection in relation
to the thickness of the composite material. The author used the methodology of assessment of the
bearing capacity of wooden structures developed by professor Yu.M. Ivanov. For the purposes of
development of optimal parameters of the "QM Glued" connection, the author identified the optimal
ratio of b, or width of the surface of connected elements, and the thickness of the composite material:
t = 1/40 b.
