The preparation of high‐filled composites by compounding with calcium carbonate (CaCO3) and polymer has received much attention. However, challenges such as enhancing the interaction between CaCO3 and the polymer and improving the performance of the resulting composites need to be addressed. In this paper, composites with a high filler content were made by adding fillers of various CaCO3 gradations into unsaturated polyester resin (UPR). The mechanical properties, curing degree, component distribution, and structural phases of resulting blends were analyzed by a universal testing machine, differential scanning calorimeter, Raman, and scanning electron microscope/energy‐dispersive x‐ray spectroscopy (EDX), respectively. Based on the research findings, optimizing the CaCO3 gradation significantly increased the strength of the resulting blends. The average flexural strength increased by 343.5%, while the average compressive strength increased by 888.9%. The composites with an optimized gradation of filler showed a significant reduction in uncured domains, leading to an improvement in the curing degree of the composites. The interfacial defects between the optimized graded CaCO3 filler and the UPR were reduced, resulting in a uniform distribution with no visible interface. The Raman and EDX analyses show that the gradation optimization technique has successfully prevented structural phase separation and enhanced the tendency to agglomerate between CaCO3 and UPR. This study proposes an effective method for developing high‐performance UPR/CaCO3 composites with a high filler content.Highlights The optimized gradation of CaCO3 was used as filler to address the weak interaction of CaCO3 with the UPR in a high‐filled UPR/CaCO3 composite system while improving the performance of the composite. The gradation optimization of CaCO3 filler can improve the morphology and reduce the porosity of the high‐filled UPR composites. The gradation optimization of CaCO3 filler can effectively improve the curing effect of UPR. Optimizing the CaCO3 gradation resulted in a significant increase in the average flexural strength (by 343.5%) and average compressive strength (by 888.9%) of the resulting blends.

“…Significant improvement in transverse properties of fiber reinforced composites have resulted from enhanced fiber-matrix interfacial strength. 1 Combined with superior matrix toughness, the possibility of out-of-plane damage of fiber reinforced composites have been well controlled. Many researchers have successfully enhanced the polymer matrix properties by incorporating nanofillers like nanoclay, carbon nanofiber, multi-walled carbon nanotube (MWCNT), and graphene nanoplatelets (GNP).…”

The effect of incorporation of micron sized aluminum trihydrate, multi‐walled carbon nanotubes, and graphene nano platelets into glass fiber reinforced epoxy matrix is investigated using dynamic mechanical analysis. The objective of the investigation was to develop polymer central core of high temperature low sag transmission conductor. The effect of individual and hybrid carbon fillers on the viscoelastic properties of the epoxy composites is investigated and discussed. The storage modulus of the glass reinforced epoxy increases by 20% at room temperature due to incorporation of carbon nanofillers. In glass transition region, the increase is higher between 40% and 60% and it varies up to 90% in the rubbery region. Key attributes of carbon filler addition are limited enhancement of storage modulus at room temperature, higher enhancement over glassy, glass transition, and rubbery regions. The carbon fillers extend the temperature range of the glassy region. The cross‐link density, filler efficiency, and degree of entanglement of fibers are estimated to understand the implications of the carbon fillers on the viscoelastic properties. The loss modulus peak of glass epoxy composite increases from 2800 to 3900 MPa with carbon fillers and the increase in glass transition temperature is 47°C. Incorporation of carbon fillers leads to increase of damping factor peak from 0.2 to 0.28. Cole–Cole plots have established the inherent heterogeneity of epoxy systems due to the presence of carbon fillers. Prediction models for storage modulus and damping factor have been proposed to highlight the influence of geometry and size of carbon filler.

The demand for sustainable and environmentally friendly practices by reducing the usage of virgin materials and minimizing the environmental impact associated with textile production has increased. However, due to the subjectivity of reuse and recycling for waste management, developing textiles with sustainable and quality yarn characteristics remains a challenge. The main goal of this experiment is to produce a new sustainable blended open end (OE)‐rotor yarn by using pineapple leaf fiber (PALF) and recycled waste fiber (RWF). OE‐rotor yarns are made in various proportions from RWFs generated from clothing wastes and bleached PALF at 20%, 50%, and 80%, respectively. To provide a more accurate evaluation, the properties of 100% PALF OE‐rotor yarns versus PALF‐RWF blended OE‐rotor yarns are compared. The evaluation of various physical properties led to the discovery that rotor yarns with up to 80% RWF‐PALF blended yarns had an acceptable number of physical attributes. The findings were encouraging given that the created yarns from RWF with PALF blended are less expensive than the yarns produced from standard raw materials. It also has a dual‐benefit for the manufacturers that it allows them to make money from the waste while also addressing zero waste management and disposal challenges.
