Table 7 Comparative overview of the mechanical properties of the developed polyurethane–cellulose composites and selected conventional and bio-based composite boards reported in the literature. Values are presented as representative ranges due to differences in material density, specimen geometry, and applied testing standards.
Material | Density (kg/m3) | Tensile strength (MPa) | Compressive strength (MPa) | MOE (GPa) | Impact strength (kJ/m2) | References |
|---|---|---|---|---|---|---|
Polyurethane–cellulose composite (this study, C30–C50) | n/a | up to ~ 13 | up to ~ 50 | 0.5–1.2 | higher than MDF (trend) | This study |
Oriented Strand Board (OSB) | 600–700 | 5–10 | 10–15 | 3–5 | moderate | Chen and He27 |
Medium Density Fiberboard (MDF) | 700–800 | 10–20 | 15–25 | 2–4 | low | EN 622–5 |
Bio-based polymer composite (natural fiber reinforced) | 900–1200 | 20–40 | 20–60 | 2–6 | moderate to high | Faruk et al. (2012) |
Waste-derived composite board (polymer-based) | 500–900 | 8–25 | 15–40 | 1–3 | moderate | Koronis et al. (2013) |
