TL;DR
This paper studies how to bond steel with pine wood, comparing different adhesives for strength and cost-effectiveness.
Contribution
The study introduces a cost-effective thermosetting adhesive mixture with high shear strength for bonding steel in wood.
Findings
Thermosetting adhesives offer a cheaper and effective alternative for bonding steel in wood.
A PF/pMDI adhesive mixed with recycled tire powder achieved high shear strengths of 1.63 N/mm2 and 3.14 N/mm2.
Ribbed steel bars produced stronger bonds compared to flat specimens.
Abstract
Combining steel with wood has been practised for many years. The issue is related to two main areas, i.e., bonding steel elements with wood so that they serve as connectors facilitating the assembly of wood elements and bonding steel elements to wood beams to improve their load-bearing capacity. In the first case, the adhesives used may be relatively expensive and more difficult to apply, whereas in the second one, especially when steel elements are glued inside the glulam (GL) beams, it is better if the adhesives used are more accessible to apply and cheaper. As it seems rational to reinforce wood with high-modulus ties, research has been carried out to compare the connection quality of commercially available adhesives that can be used for this purpose. Moreover, thermosetting adhesives have been applied as an alternative and cheaper solution. Thermostat adhesives also have a high pH…
