Heat Resistance of Glued Finger Joints in Spruce Wood Constructions

BioResources, 2014
The heat resistance of glued spruce wood was evaluated for different joint types and adhesives. Bending strength, modulus of elasticity, and also fracture evaluation were investigated on glued spruce samples made by the finger-jointed principle.

Optimization of Starch–Tannin Adhesives for Solid Wood Gluing

Polymers
Bio-based solutions for solid timber gluing have always been a very sensitive topic in wood technology. In this work, we optimize the gluing conditions of a starch–tannin formulation, which allows high performance in dry conditions and resistance to water dipping for 3 h, allowing for the D2 classification to be reached according to EN 204.

Numerical simulation of bubble rising behavior in a tannin-based foaming precursor resin

Heliyon
A two-dimensional volume of fluid (VOF) model was developed to simulate the deformation of the bubble, the end speed of bubble rise, the distance of bubble rise and the movement trajectory in different initial conditions of tannin-based foaming precursor
