“…Recently, these wastes have attracted the scientific community to utilize them as filler material in polymeric composites. Blas furnace slag is being utilized mostly as a filler material in the polymeric resin for the development of polymer composites [4][5][6]. LD slag and LD sludge are also explored as a single filler and in combination with other reinforcement for the development of a hybrid composite [7,8].…”

This article reports an investigation of the thermal behaviour of the epoxy/LD-slag composites prepared by hand layup method at varied loading of filler from 0 wt. % to 40 wt. %. The main aim of the work is to establish hazardous industrial waste as a filler material for the development of polymer composites.The thermal conductivity of neat epoxy is 0.15 W/m-K and the same improves to 0.292 W/m-K with the addition of 40 wt. % LD-slag. The addition of LD slag appreciably improves the epoxy matrix's thermal stability by increasing its degradation temperature at different levels along with the enhancement in the char residue. The maximum glass transition temperature of 74.74 o C is attained for a filler loading of 20 wt. %, whereas, a negligible reduction is observed at higher filler loading. Further, the material's specific heat capacity also progressed with the inclusion of LD slag and reached 1.115 kJ/kg-o C showing an increment of 57.7 over the neat epoxy resin for a combination of epoxy/40 wt. % LD slag composite. The coefficient of thermal expansion gainfully declines with filler loading and decreases by 14.18 % for 40 wt.% of LD slag. The minimum coefficient of thermal expansion value registered is 59.3 × 10 -6 / o C.

The necessity to adapt sustainable development, green chemistry and industrial ecology leads to the creation of newer materials and the utilization of waste. In this context, this work aims at exploring the feasibility of the fabrication of hybrid composites comprised of a polymeric resin reinforced with a natural fiber (hemp) and an industry waste filler (dolomite dust). While the hemp fiber content is kept constant, epoxy‐based hybrid composites are fabricated with different weight percentages of dolomite dust using the conventional hand lay‐up route. The microstructural features of the constituent materials are studied using stereo and scanning electron microscopes which show the shape and size of dolomite particles and the arrangement of fibers. An x‐ray diffraction analysis revealed the presence of hematite, graphite, lime and manganite. The presence of functional groups like hydroxyl, carboxyl and azide is ascertained from the transmittance spectra of Fourier transform infrared spectroscopy. The density and void fractions are increasing with the amount of filler particles in the composite. It is observed that the tensile and flexural strengths of the composites marginally drop with increase in dolomite dust content, but there is a reasonable improvement in their inter‐laminar shear strength, micro‐hardness and impact strength values.
