Strategies to mitigate these challenges include replacing these polymer composites with smart materials, ceramics, or metamaterials, using filler doping, surface modification, functionalization, and multilayer dielectric structures, incorporation of porous structure into the polymer to increase air gaps, and use of hybrid composite, nanomaterials, 3D materials, or low-cost alternatives with improved or at least comparable performance. Maintaining long-term and reliable performance at higher temperatures is still a challenge [26]. Some of the scientific and technical challenges include how to (i) realize the synergistic improvement of the wave transmission performance, mechanical properties, and high-temperature resistance through integrated structure/function design for new generation radomes [18]; (ii) design and synthesize high performance composite radomes to withstand high working temperatures while keeping their stability and performance intact [10]; (iii) improve the surface characteristics, interface properties, and interfacial adhesion of fibers; (iv) analyze and characterize the surface performances of fiber composites and the transmission process of electromagnetic wave at the interface; (v) establish wave transparent models to relate the molecular chain electromagnetic wave transmission mechanism and characteristics; and (vi) dynamically simulate the reflection, loss, and transmission process of electromagnetic wave, and to illustrate the transmission mechanism [25]. Glass fibers possess several advantageous characteristics such as low \(\varepsilon_{\mathrm{r}}\) and \(\delta\), reasonable mechanical strength, higher softening point, and good adhesion compatibility with epoxy resin which render them suitable as reinforcement in composites. Additionally, they offer benefits, including excellent dielectric properties, high strength to weight ratio, high modulus, corrosion resistance, high-temperature resistance, and a minimal environmental footprint [27]. In a composite structure, the combined area or link between the resin and fibers is known as the interface. The fiber-resin adhesion is responsible for weak or strong interfaces which play an important role in the functionality of reinforced composites [28]. Due to their excellent dielectric, mechanical, and thermal properties, quartz fibers are recognized as the best fibers among the glass fiber family [29]. Moreover, they have good adhesion compatibility with polymeric resins [30]. Compared to pure epoxy composites, reinforced glass fiber composites can withstand higher temperatures (\(\geq\)300 \({}^{\circ}\)C) for longer durations while retaining their mechanical and thermal stability along with the desired electric performance [31]. Glass fibers are suitable in electronic applications and radome manufacturing due to their dielectric stability, low moisture absorption, good mechanical, and thermal stability [32]. However, the final properties of composites depend on the properties and proportion of the constituents, which can be estimated through the rule of mixtures for the evaluation of composite properties [33]. Extensive research has been carried out to investigate the properties of fiber-reinforced composites [12]. Selecting the most suitable reinforcing fibers [34] and polymer matrix [35] is beneficial to obtaining polymer fiber-reinforced composites for radome applications [36]. Keeping in view the above challenges, the current study aimed to fabricate composite reinforcing the polymer matrix with glass fibers for radome applications which will have excellent wave transmission performance, reasonable mechanical strength, and high-temperature resistance. However, this study is concentrated on the influence of embedding quartz fiber quantity to attain combination of specific characteristics include low \(\varepsilon_{\mathrm{r}}\) and low \(\delta\), mechanical integrity, and low moisture absorption. A fiber-reinforced composite radome material was fabricated by embedding a small fraction of quartz fibers in epoxyresin.
