In recent years, cross-laminated timber (CLT) has been used in multi-story wooden buildings and in the civil engineering field. However, the manufacturing and construction costs of CLT hinder its use. Hydraulic presses are used to manufacture domestically produced standard CLT panels. However, some factories overseas manufacture CLT panels using vacuum presses, whose manufacturing cost is lower than hydraulic presses. Although the compression pressure of the vacuum press is small, only a vacuum pump can be used to press with large sheet covering the material, and CLT of various sizes and shapes can be manufactured with lower manufacturing costs. This study aims to examine the possibility of using vacuum presses in the manufacture of CLT made from domestic timber. Test species and adhesive conditions were prepared using vacuum presses and hydraulic presses respectively, and bending performance and adhesion durability were evaluated.
