Wood cement composites reinforced with polypropylene fibre

Journal of Achievements in Materials and Manufacturing Engineering

Vol. 76, nr 2

Purpose: This paper presents basic investigation into the effect of different lengths of polypropylene fibres in surface layers of wood cement boards is investigated on their physical and mechanical properties including density, moisture content, thickness swelling, modulus of elasticity, modulus of rupture, internal bond strength and screw withdrawal strength of the samples. Design/methodology/approach: Wood cement composites with a dimension of 400x400x10 mm were produced using three different lengths of PPF and with a constant wood/ement ratio (1/3 by weight) and target density (1.2 g/cm3). Findings: The results showed that PPF usage had statistically significant effect on the properties of wood cement composite. The highest mechanical properties were obtained from samples of control-WCB group while the lowest moisture content and thickness swelling were observed in PPF reinforced cement boards. Research limitations/implications: It was observed that the PPF usage decreased thickness swelling values of the boards up to 80%, according to wood. Using wood and PPF together resulted in better mechanical values of the boards compared to using PPF alone and higher MOR and MOE values than the EN 634-2 standards. Physical properties of all the boards satisfied the minimum requirements for the EN 634-2 standard. Originality/value: The results can be assessed as novel in the range of usage a modified material in wood cement board.
