Recent research has unveiled promising advancements in the realm of hybrid composites, particularly significant for the construction sector. A team led by Harini Sosiati from the Department of Mechanical Engineering at Universitas Muhammadiyah Yogyakarta has explored the mechanical and physical properties of nylon fiber mesh (N), woven glass fiber (G), and unsaturated polyester (UPE) resin, enhanced with various oxide ceramic particles. The findings, published in ‘Materials Research Express’, shed light on how these materials can be optimized for better performance in construction applications.
The study meticulously examined the influence of different stacking sequences of nylon and glass fibers—specifically configurations like GGNNGG, GNGGNG, NGGGGN, and NNGGGG—on the performance of the composites. “Our goal was to identify the best combination of ceramic particles and stacking sequences to enhance composite properties while minimizing water absorption,” Sosiati explained. The results showed that composites reinforced with aluminum oxide (Al2O3) and zinc oxide (ZnO) exhibited superior mechanical properties, with the Al2O3 variant demonstrating lower water absorption rates, making it particularly appealing for construction applications where moisture resistance is crucial.
The research highlights that the N/G/UPE-2Al2O3 composite, with a flexural strength of 125.12 MPa and an impact strength of 84.2 kJ m−2, could serve as a viable biomaterial in various construction scenarios. This development is not just an academic exercise; it has tangible implications for the construction industry, where the demand for durable, lightweight, and moisture-resistant materials is ever-growing. The potential for these composites to replace traditional materials could lead to more sustainable building practices, reducing overall material costs and enhancing structural integrity.
Sosiati’s team utilized a two-step manufacturing process involving hand lay-up and press molding techniques, which could be scaled for commercial production. The research opens avenues for further exploration into hybrid composites, suggesting that variations in material composition and stacking sequences could lead to even more robust solutions in the future.
As the construction sector increasingly seeks innovative materials to meet sustainability goals, this research stands at the forefront, paving the way for the next generation of composite materials.
