A recent study has shed light on the mechanical properties of Fiberglass Reinforced Polymer (FRP) composites, which are increasingly popular in the construction of small boats in Indonesia. Conducted by Ismail Abdi from the Research Center for Hydrodynamic Technology, this research aligns closely with practical yard practices in lamination, addressing a gap in existing literature that often overlooks real-world applications.
The study examined various fiberglass layer configurations to determine their impact on tensile and bending strength, crucial factors for ensuring the durability and safety of marine vessels. Notably, samples from Bojonegara and Makassar 3 demonstrated compliance with the standards set by the Indonesian Classification Bureau, Korean Register, and American Bureau of Shipping. These samples not only met the necessary criteria but also exhibited the best specific strength among those tested.
Abdi’s research utilized Analysis of Variance (ANOVA) to assess the significance of different fiberglass configurations. The results indicated that the number of layers significantly influences strength, with four or five layers providing similar tensile and bending strength. This finding is particularly valuable for shipbuilders, as it suggests that investing in these configurations could optimize performance without incurring excessive costs.
Furthermore, the study highlighted the importance of the Unsaturated Polyester Resin brand used in the lamination process. While it had a notable impact on tensile strength, its effect on bending strength was less significant. This insight can guide manufacturers in selecting materials that enhance the overall structural integrity of their vessels.
“The samples from Bojonegara and Makassar 3 can be recommended for practitioners in FRP shipyards as they have met the requirements of international regulations,” Abdi stated, emphasizing the commercial viability of these materials.
The implications of this research extend beyond compliance; they present a commercial opportunity for the maritime sector in Indonesia and beyond. By adopting these optimized fiberglass layer configurations, shipbuilders can improve the performance of their vessels, potentially leading to increased market competitiveness. Moreover, as the demand for lightweight yet strong materials in marine construction continues to rise, this study published in ‘Curved and Layered Structures’ provides a solid foundation for future developments in FRP applications.
