In this study, we investigated property differences and failure mechanisms of hot-pressed, binder-free wood fiber composites. Random-in-plane microfibrillated lignocellulose (MFLC) composites showed better mechanical properties than microscale wood fibers WF due to stronger strain-hardening from lower porosity and better interfibrillar adhesion, provided by the intrinsic lignin-hemicellulose binder. Axially oriented wood fiber composites (O-WF) reached comparable mechanical properties to random MFLC, with lower values for eco-indicators. Investigation of these differences are meaningful.
