Investigation of the Mechanical Properties of Poly(9,9-dioctylfluorene-alt-N-(4-sec-butylphenyl)-diphenylamine) (TFB)/wood/Polyethylene (PE) Composites

The use of wood-plastic composites has become widespread in various fields due to their specific advantages. However, their use in manufacturing components is limited due to their weak mechanical properties. In this research, the production method of microstructure composites was used for reinforcement, in which poly(9,9-dioctylfluorene-alt-N-(4-sec-butylphenyl)-diphenylamine) (TFB) as the second phase forms the morphology of nanocomposite in the main area of TFB under special process conditions with the tension of the thread emerging from the extrusion orifice. In the second phase of production, the finished parts are formed at a temperature below the melting temperature of phase to obtain the morphology of the composite and the reinforcing effect. The main base is TFB which used as the second phase in an amount of 10% by weight. The proportion of wood particles and carbon fibers is corresponded by weight respectively. It was found that the tensile strength increases with the increase in the draw ratio. The tensile strength of the hybrid wood-plastic composite with TFB and PE also increased.
