techniques vary from one builder to another
In 1949, the first board with a Styrofoam core was built. While this basic construction has remained the same for many years, the shapes and styles have certainly changed. The process of surfboard design and construction is surprisingly complicated today, especially when you consider that the surfboards used a century or Oxygen Absorber Films Manufacturers two ago were literally boards cut from a single tree trunk. The fin of the board is made either of wood or of laminated fiberglass and resin layers. When done, the leg leash and fin are attached to the board. Some builders use computer-guided machines to do this, while many surfboard builders often use only their experienced eye to guide the shaping process. The core of the board is covered with a fiberglass cloth, and then a layer of polyester laminating resin.
This early style consisted of two hollow, molded pieces with a piece of redwood running down the center for stability.While for centuries surfboards were solid wood, the modern era of surfboard design began in 1946, a date which marks the first fiberglass surfboard design.Although there are certainly many brands offering standardized and mass-produced boards, the highest quality surfboards are individually crafted by talented surfboard makers. The outline is cut and then smoothed into its final shape. Today, surfboard makers continue to experiment in the search for the perfect board. The first truly modern boards were built beginning in 1958. Often, a redwood stringer, or stabilizer is contained within the core.Many surfing aficionados often wonder exactly how the board they are riding was built.
Liquid polyurethane is poured into the mold in order to form a dense foam.Now, the core is cut in half, from the nose all of the way to the tail, to allow for the insertion of the stringer. Today, nearly every surfboard design uses this mode of construction. Although techniques vary from one builder to another, most surfboards are built one at a time starting with the formation of the foam core. The purpose of a stringer is to provide stability, keeping the board from snapping in half. Serious surfers may use as many as five or even ten different boards for different surf styles and beaches..Now, it’s time to finish the shaping of the board. These surfboards, designed by Hobie Alter, were produced with a polyurethane foam core and fiberglass shell.
During the final finishing process, excess resin is sanded away, leaving a glossy and perfectly smooth coating. This buoyant center was enclosed not by fiberglass but by thin sheets of plywood sealed with resin.Typical surfboards sold today have a polyurethane core, surrounded by fiberglass and polyester resins. Over the past few decades, boards have grown shorter and longer several times, with popular designs including one fin, two fins, or three fins. Glued between the two halves, the core is then clamped back together. Once cooled, the surfboard core is removed from the mold. The blank is now ready to be covered in a fiberglass and resin shell. Known as a blank, most surfboard builders form this core in a large mold that is roughly the shape of Packaging Film Manufacturers the finished surfboard.
