Which manufactured board is made by bonding wood fibers?

• A. MDF
• B. Plywood
• C. Chipboard
• D. Blockboard

Answer: (A)

Wood-based boards come in several types based on how the wood is processed and bonded. The board made from wood fibers is created by grinding timber into fine fibers, mixing them with a resin adhesive, laying the mixture into a mat, and then hot-pressing it to fuse the fibers into a dense, smooth panel. This produces a uniform surface and consistent strength throughout the sheet, which is why MDF is prized for painting and finishing. In contrast, other boards use different structures: plywood is built from thin layers (veneers) glued together in alternating directions for strength; chipboard uses larger wood particles rather than fibers; blockboard has blocks or strips of wood in the core with veneers on the outside. None of these rely on bonding fine wood fibers like MDF does, so the board made by bonding wood fibers is the one described.
