LAYERED PRODUCTS

Description

B32 encompasses the manufacture, treatment, and properties of composite materials formed by bonding or assembling multiple layers of different substances into integrated structures. This class covers laminated products, sandwich structures, coated substrates, and multi-ply materials where individual layers provide distinct functional properties (mechanical, thermal, electrical, or protective). Applications include decorative laminates, thermal insulation panels, reinforced composites, and industrial coatings on various base materials. The classification focuses on the structural and manufacturing aspects of layered constructions rather than the properties of individual component materials, which are covered in related material-specific classes.
