maintenance techniques to address this. Therefore, innovation is needed in the form of wood-based materials that are relatively easier to obtain but possess mechanical properties that meet the criteria of fishermen in building fishing boats. Wood-based composite (WBC) refers to composite materials that incorporate wood. WBC is generally manufactured for specific purposes, such as achieving better mechanical properties and obtaining environmentally friendly materials (Zanuttini and Negro, 2021). Despite various efforts and research to improve wood materials, innovation in developing wood materials for ship structure applications is still relatively lacking. This article reviews wood composite technology innovations that have the potential to be applied to ship structures and interiors. These technological innovations include superhydrophobic technology to reduce corrosion, fireproof material with a transparent coating that maintains the aesthetic value of the wood grain, PLA composite with more environmentally friendly wood, and aluminum tube composites with wood filler to improve mechanical properties. By reviewing these innovations and tests, it is hoped that more effective solutions can be found to improve traditional wooden ships' performance and durability in facing the maritime environment's challenges. 2. Superhydrophobic Wood for Enhancing Anti-Corrosion and Mechanical Strength Superhydrophobic treatments have significant potential for application in wooden ship structures due to their ability to enhance wood's corrosion resistance while increasing its strength. These treatments utilize methyltrimethoxysilane (MTMS) to improve wood performance by isolating the wood from direct contact with water, thereby reducing water absorption (Chen et al., 2019; Tang et al., 2016; Zhang et al., 2017). This process helps to avoid issues such as matrix cracking, deformation, biological degradation, and surface discoloration. Figure 2 illustrates the process for producing Superhydrophobic wood.

The wood beams undergo vacuum and pressure treatment using MTMS, C₂H₅OH, and O₂ solutions, followed by air drying for 10 days to produce Hydrophobic Wood (H-Wood) (Xu et al., 2011; Tang et al., 2016; Fei et al., 2014; Sharma et al., 2020). Subsequently, H-Wood is processed using the Chemical Vapor Deposition (CVD) method, involving MTMS and a MeOH/NH₂OH mixtur e in a desiccator heated to 103°C, resulting in Superhydrophobic Wood (SH-Wood) (Wang et al., 2020, Zheng et al., 2017). Mechanical strength testing on superhydrophobic wood was conducted using the UTM5105 machinery following National Standards GB/T 1935 – 2009 and GB/T 1939 – 2009. Anti-corrosion testing was also performed. The corrosion resistance of superhydrophobic wood was assessed by immersing samples in HCl solution (pH = 1) and NaOH solution (pH = 13). The exposed surfaces' Water Contact Angle (WCA) and Sliding Angle (SA) were measured. The treatment involved soaking for 4 hours and heating at
