“…A tensile strength of ∼29 MPa was observed for both HGM filled composite. The decrease in tensile strength can be attributed to the spherical shape of the HGM fillers which makes them a stress concentrator 34 in the continuous matrix and also during the tensile test, the filler particles breakdown due to limited strength of its glass shell. 35 Furthermore, in case of the hybrid composites the tensile strength initially decreased for BM/8 f -CF/10G (59.22 MPa) and BM/10 f -CF/10G (69.80 MPa) in comparison to their counterpart BM/8 f -CF (69.95 MPa) and BM/10 f -CF (71.13 MPa), respectively.…”

Light-weight hybrid composites of relevant industrial applications were prepared using surface functionalized hierarchical carbon fibers ( f-CF), silane treated hollow glass microspheres (HGM), and a blend of polypropylene (PP) and maleic anhydride-grafted-styrene ethylene butylene styrene as the base polymer matrix. The f-CF were prepared by coating amine functionalized carbon nanotubes onto silane treated CF using an ultrasonic assisted electrophoretic deposition technique to improve fiber-matrix interfacial adhesion. For hybrid composition of 20 wt.% f-CF and 10 wt.% HGM, the tensile strength and modulus improved by ∼141 and ∼536% over neat PP while flexural strength and modulus increased by ∼118% and ∼583% respectively. Impact strength of 11.06 kJ/m2 was obtained and uniform dispersion and distribution of f-CF and HGMs was observed in Scanning electron microscope (SEM) images. Desirable reduction in density and melt viscosity along with improvement in composite stiffness were observed due to addition of HGM filler. Compared to PP, the crystallization temperature increased by ∼12°C while a maximum decrease of ∼5°C in melting temperature was obtained for the hybrid composites. Crystallinity of the hybrid composites decreased with an evident β crystal formation brought in by the nucleation.

The modern development of the construction industry needs to find ways to create new competitive materials. Such materials are polymer composites, since the range of their application can be wide, due to the possibility of regulating their technical properties. This work presents a research on the development and production of polymer composites and products from them with the improved mechanical properties by adding finely dispersed techno-genic mineral raw materials as a functional filler. As a dispersed filler of the polyvinyl chloride composition, waste from the production of refined silicon was used, which is dust from the entrainment of furnaces captured by an electrostatic precipitator. To predict the characteristics of the materials obtained, the applicability criteria of techno-genic raw materials in the polyvinyl chloride composition are studied. Studies of the mechanical and operational properties of the obtained composites have confirmed the possibility of using techno-genic raw materials as functional fillers that affect the mechanics, durability, and also significantly reduce the cost of finished products.

“…The purpose of the work is to create polymeric compositions based on polyvinyl chloride filled with industrial waste products, and to analyze the effect of particle size characteristics of various fillers on the properties of the materials obtained. A number of studies previously conducted [3] have established that finely dispersed mineral industrial waste can not only reduce the cost of PVCcompositions, but also improve the physical and mechanical properties, reduce the coefficient of linear thermal expansion -compression, improve resistance to UV exposure, reduce flammability [4][5][6][7][8].…”

The article is devoted to research in the development of composite materials based on polyvinyl chloride and industrial waste from the metallurgical, energy and mining industries. The properties of dispersed waste have been studied, which make it possible to speak of the possibility of their use as fillers for polymer compositions. A comparative analysis of the tested physical and mechanical properties is carried out, depending on the characteristics of the particle size of the fillers. It was revealed that from the point of view of construction materials, all the wastes under study can be used as fillers. The development will make it possible to dispose of industrial waste to obtain useful products and save natural non-metallic materials used in the creation of composites.
