This paper presents the method of using glass fibre with carbon deposit (GFCD), derived from the recycling of wind turbine blades, for production of composite materials based on poly(vinyl chloride) (PVC). Composite materials containing from 1 to 15 wt% of GFCD were produced by plasticising with a plastographometer and then by pressing. The processability and performance were studied. Mechanical properties in static tension, impact strength, and thermal stability were determined. Glass transition temperature was also determined by means of the dynamic mechanical thermal analysis (DMTA). The GFCD percentage of up to 15 wt% was found not to slightly affect the change in the processability, thermal stability, and glass transition temperature. PVC/GFCD composite materials are characterised by a definitely greater elastic modulus with simultaneous decrease of tensile strength and impact strength. An analysis with scanning electron microscopy revealed good adhesion between the filler and the polymer matrix.

Electrospun poly(vinyl chloride) (PVC) nanofibrous were prepared by electrospinning. Various concentration of polyurethane (PU) were added to PVC solution for plasticization of the electrospun nanofibrous. The pristine and plasticized nanofibrous were characterized by field emission scanning electron microscopy (FE-SEM), differencial thermal analysis (DTA), and thermogravimetry analysis (TGA), respectively. Thermal properties form DTA and TGA results indicated that the addition of PU decreased glass transition temperature (Tg) of PVC and increased heat resistance of PVC nanofiber. The dielectric constant of plasticized nanofibrous measured using precision LCR meter indicated that the membrane were dense.
