🏗️ This study examines the impact of accelerated aging on the dimensional stability and mechanical performance of wood-based panels designed for exterior applications. Three types of panels are investigated: two particleboards (PB1 and PB2) bonded with phenol-formaldehyde adhesive, and a medium-density fibreboard (MDF) bonded with polymeric methylene diphenyl diisocyanate. The objective is to assess their resistance to severe environmental conditions simulated in the laboratory, including repeated wetting and drying cycles.
The results show that PB2 offers the best stability and retains its mechanical properties the most effectively, while PB1 shows intermediate performance and MDF is the most sensitive (high swelling, low strength). In conclusion, PB2 is suitable for demanding exterior applications, whereas PB1 and MDF are better suited to semi-protected environments.
