AI overview
Plywood is an engineered wood product made by gluing together thin layers of wood veneer in alternating grain directions, which gives it strength and stability. It's widely used in construction and manufacturing because this cross-grain structure makes it resistant to warping and splitting, while being lighter and more affordable than solid wood.

胶合板也叫夾板、多层材（英語：Laminated Veneer Lumber，縮寫LVL，更通用的英文用語是Plywood）是第一种发明的科技木材。由比较薄的木单板制作。由相邻两层木纹相互垂直的木片（单板）叠合。木片之间涂上强力胶，在一定温度一定压力下压合而成。通常用酚醛胶、胶和三聚氰胺胶。使用胶合板代替木板的普遍原因是因为胶合板具有很强的抗破裂、抗收缩、抗扭曲和普通的高强度属性。胶合板與Glued laminated timber（Glulam）不同。
