The hand-lay-up method is one of the oldest and most traditional techniques used in composite production. This method involves laying layers of reinforcing fibers onto the mold surface and saturating them with resin as the matrix. Despite advances in automated composite production methods, hand-lay-up remains a versatile and widely used process for producing composite parts with complex geometries and custom designs. While it may have limitations in terms of uniformity and labor-intensity, its cost-effectiveness and flexibility make it an efficient and inexpensive method, particularly for small-scale production, prototyping, and repair applications.
