Prediction of the modulus of elasticity of building materials based on wood-polymer composites

Abstract

Abstract The modulus of elasticity of mixtures of two polymers in glassy or crystalline states is predicted. In addition, the elastic modulus of composites containing a mixture of organic polymers and a mineral filler is predicted. The preparation of wood-polymer composites increases the elastic modulus from 2400 to 4660 MPa under tensile conditions. The introduction of a mineral filler in the form of CaCO3 leads to an increase in the E modulus to 3230 MPa with a CaCO3 content relative to the wood filler of 42%. The prediction of the elastic modulus for composites containing moso bamboo as a wood filler shows that with this content of wood filler, the modulus of elasticity can increase to 4400 MPa.
