“…The combination of two kinds of fillers in a single matrix can show advantages of both fillers. The following different combinations of fillers can be used to produce hybrid composites: banana/glass [ 12 ], kenaf/glass [ 13 ], wood/glass [ 14 ], palm/kenaf [ 15 ], and biocarbon/basalt [ 16 ]. Hybridization can help to change the properties of different composite applications.…”

Basalt/glass fiber polypropylene hybrid composites were developed as subjects of investigation, with the aim to characterize their properties. An injection molding machine was used to produce the test samples. The following three different tests, at various specimen temperatures, were conducted: tensile test, three-point flexural test, and Charpy impact test. To determine fatigue behavior, the samples were uniaxially loaded and unloaded. Mechanical hysteresis loops were recorded and the dissipation energy of each loop was calculated. To determine the adhesion and dispersion between the fibers and the matrix, the fractured surfaces of the various specimens, after the tensile test, were investigated using a scanning electron microscope. The results show that the production of a composite with both basalt and glass fibers, in a polypropylene matrix with maleic anhydride-grafted polypropylene, can be successfully achieved. The addition of the two types of fibers increased the tensile strength by 306% and the tensile modulus by 333% for a composition, with 20% by weight, of fibers. The material properties were estimated with the help of a simulation software, and validated with a FEA. A satisfactory correlation between the simulation and measurement data was achieved. The error lays in a range of 2% between the maximum stress values. At a lower strain (up to 0.02), the stress values are very well matched.

“…Table 1 shows the variation in the CTE of rPE depending on all cellulose types and additive ratios. In general, it has been stated that with the increase of the reinforcement ratio in composites, swelling due to the trapped moisture in the composite and expansion, as a result, will occur 65 . However, the thermal expansion coefficient of the produced composites is lower than that of rPE.…”

Hemp is a good option for polyethylene additives because of its high cellulose and fibrous content. This study aims to modify natural hemp fibers with the maleic anhydride/ionic liquid method, manufacture the composites, and compare the thermal and mechanical properties of natural hemp fiber and hemp cellulose. In this study recycled polyethylene as a binder, and filling ratios between 0 and 50 (wt/wt)% are investigated as a parameter. Differential scanning calorimeter and thermomechanical analysis were performed, and it was determined that the coefficient of thermal expansion from 973 to 147 ppm/K. It was determined that the strength of composite materials obtained from cellulose fibers with maleic anhydride/liquid ionic modification improved by around 20% from 19.5 to 24.4 MPa. In addition, as a result of scanning electron microscope analyses performed on the fractured surfaces, it was determined that the pressure, temperature, and time were suitable for producing composite materials. This work shows the potential of recycled polyethylene/hemp composites as a sustainable green material with simple fabrication procedure and useful mechanical and thermal properties.

“…In the rubbery zone, the loss modulus (E″) also falls. According to earlier research, the peak of E″ provided transition temperature values that were more trustworthy than the peak of tan δ [2,26,27]. The transition temperature is raised by the fiber loading and fiber treatment.…”

Dynamic mechanical analysis (DMA) is a helpful technique in the evaluation of natural fiber composites (NFCs) for investigating the viscoelastic behavior with respect to time, temperature, and frequency and calculating the phase shift. The authors have previously studied the DMA behavior of reinforced composites made of single (mono) and synthetic fibers. In this work, the DMA responses of bio composites, nanocomposites, and hybrid natural fiber composites are compared, and the factors influencing the responses are evaluated. Fiber loading, filler addition, fiber treatment, fiber stacking, and matrix all affect how viscoelastic NFCs behave. Previous investigations have indicated that the ranges for the storage modulus are 2000 MPa to 5800 MPa, the loss modulus is 150 MPa to 450 MPa, and the tan δ is 0.2 to 0.6. The nanocomposite's mesh reinforcement improves the interaction between all of its constituent parts, which raises the storage modulus. More specifically, because of the better component-to-component contact in nano composite, the mesh size of the reinforcement improved the storage modulus. This review study has contributed to a broad understanding of the viscoelastic behavior of fiber composites utilized in automobile, aerospace, building science, housing, textile, and food packaging applications.
