Composite panels are lightweight building materials that offer similar strength to traditional wood or steel. There are three types: engineered wood, aluminum, and fiberglass. They are used in various applications, from structural stability to furniture and transportation industries.
A composite panel is a type of building material used in place of traditional wood or steel. These panels are much lighter than solid wood or steel, yet offer similar levels of strength and structural support. There are three basic types of composite panels, including engineered wood, aluminum, and fiberglass units. Each of these panels may consist of multiple layers of the same material or a lightweight core sandwiched between sheets of some type of protective material.
An engineered wood composite panel is typically made from pressed wood fibers or sawdust mixed with epoxy resin. The wood is shredded or ground into a fine pulp, then dried. The dried fibers are mixed with the epoxy resin and formed into sheets under high levels of heat and pressure. Depending on the type of wood fibers used, these panels may be known as medium density fiberboard (MDF), particleboard, or hardboard.
Composite wood panels are used in many different building applications and have greatly reduced the demand for plywood. Engineered wood panels are used to add structural stability to wall framing or to build floors and roofs. Since these panels generally have a smooth and uniform appearance, they can also be used to make doors and furniture. Many cabinets and other types of furniture are made using a composite board topped with a thin layer of wood veneer. This can be used to mimic the look of solid wood at a fraction of the cost.
Aluminum composite products are often known as “sandwich panels”. They consist of a lightweight core wrapped in thin aluminum foil. The core can be made using rigid foam or honeycomb-shaped resin board. These panels offer similar levels of strength to traditional steel construction, yet the weight is significantly reduced. These panels are used in the transportation and aerospace industries to create lightweight vehicles and venues that are still strong enough to carry a full load.
A composite panel can also be made from a combination of fiberglass, foam, and epoxy resin. Typically these materials are sandwiched so that sheets of fiberglass surround a foam core. This type of composite panel is commonly used in water based applications. Many surfboards and kayaks are made from fiberglass panels, as are boats and other vessels. The light weight of the panels helps ensure the vessel stays afloat, while the high level of strength of the panel allows the vessel to carry passengers or cargo.
