“…This reduction in flexural strength of BEZ composites at higher wt% loading of ZnO nanoparticles into the epoxy matrix is due to agglomeration of ZnO nanoparticles beyond 2 wt% inclusion into the epoxy matrix. Similar observations were made by Thipperudrappa et al, [ 49 ] Samad et al, [ 50 ] Torres et al [ 51 ] and Garcia et al [ 52 ] The agglomerated ZnO particles tend to get unevenly distributed within the matrix which reduces the toughening effect imparted by the otherwise evenly distributed nanoparticles, to the epoxy matrix and thus, rendering the weak and brittle epoxy matrix vulnerable to external loads. This can be visualized through SEM images illustrated in Figure 4.…”

This paper discusses the fabrication of nano ZnO filled epoxy/basalt fiber composites and investigates the effect of such hybridization on the mechanical properties of the composites. The epoxy resin is modified by the addition of ZnO nanofiller in different wt.% (1-5 wt%). The dispersion of the nanofiller within the epoxy resin is brought about by sonication technique. The composites are fabricated through wet layup followed by curing under compression molding. To ascertain the effect of resin modification, flexural and tensile strengths are evaluated. The inter-laminar shear strength (ILSS) is determined to identify the compatibility of the ZnO nanofiller with the epoxy and the basalt fibers. The improvement in the ILSS indicates thorough wettability being achieved between all the composite components. The addition of ZnO nanofiller improved the flexural strength, while there was no remarkable improvement in the tensile strength of the ZnO modified epoxy/baslat (BEZ) composite. Maximum improvement in the strengths is observed for BEZ2 composite with 2 wt% of ZnO nanofiller. For BEZ2 composite, the flexural and tensile strength increased by about 22% and 9.78% respectively in comparison to unfilled BEZ0 composite. The ILSS for BEZ2 composite improved by 21.74% in comparison to BEZ0 composite. In addition, more than 2 wt% addition of the ZnO nanofiller resulted in the reduction of flexural, tensile and ILSS of the composite due to agglomeration. Such agglomeration resulted in the failure of the composite due to delamination, matrix cracking and fiber fracture as observed through scanning electron microscopy images of the fractured composites.

The sustainable use of agricultural waste to generate valuable products while minimizing environmental burdens is increasing rapidly. Multiple sources of fibers have been intensively studied concerning their application in various fields and industries. However, few publications have extensively discussed the property’s performance of oil palm empty fruit bunches (OPEFB) composites. With main properties similar to composites currently listed for industrial applications, OPEFB is worth listing as a potential composite for industrial applications and non-structural material alternatives. OPEFB-reinforced polymer composites are expected to be applied to automotive interior parts. This study aims to determine the effect of adding zinc oxide (ZnO) and polyurethane on OPEFB-reinforced polymer composites for automotive interior parts. This composite was produced using the hand lay-up method with 70% resin, 15% OPEFB fiber, 15% polyurethane as a blowing agent, and four variations of ZnO at 5%, 10%, 15%, and 20%. The OPEFB particle sizes are 40, 60, 80, and 100, respectively. The composite was examined to determine mechanical, morphology, chemical, and thermal characteristics. It was observed that the addition of 20% ZnO caused ZnO agglomeration, weakening the interfacial bond between OPEFB particles, polyester, polyurethane, and ZnO filler. Overall, the results showed that adding ZnO and polyurethane to the composite increased tensile, compressive, flexural, and impact strength, as well as thermal stability with more significant values up to 160%, 225%, 100%, 100%, and 4.3%, respectively. This result depicted that the best composition was specimens with 15% ZnO and 149 microns OPEFB fibers particle size. It is considered a promising candidate to be applied in automotive interior components.

“…It has been shown in the study that thermal stability and degradation delay in composite materials can also be achieved by adding nano‐filling materials to the material composition in an appropriate amount. [ 60 ] Thus, additives will provide composite materials with superior thermal stability in high‐temperature applications. [ 61 ]…”

Composite structures have become one of the most preferred materials in the automotive industry by being improved day by day with their high strength per weight performance as well as their lightness. Natural fiber reinforced composite structures have an important share among all composite forms with recent developments. In this study, composite products in which epoxy resin is the matrix element with different stacking orders were produced by vacuum assisted resin transfer method. Basalt fabric was hybridized with carbon fabric and aramid fabric and the effect of this hybridization on thermal properties, mechanical properties, and morphological effects were examined. The mechanical test results indicated the tensile strength of the basalt/carbon hybrid configuration composite structure gave %40.18 better results than the basalt/aramid hybrid configuration structure. In terms of microhardness, in basalt/carbon hybrid configuration %22.34 better results were obtained in comparison with basalt/aramid hybrid configuration. Moreover, thermal analysis results displayed hybrid samples increased the combustion initiation temperature compared to homogeneous samples. In addition, the dominance of carbon fabrics was observed in the determination of cold crystallization temperature in hybrid samples, while basalt materials were predominant in melting temperature. Results of the article displayed that the carbon fiber hybridization to basalt fabric will greatly improve the deformation resistance and heat resistance of the materials compared to the aramid fabric hybridization process.
