Corvette fenders and boat dinghies are commonly manufactured this way. It is very different from the hand lay-up process. The difference comes from the application of the fibre and resin material to the mould. Spray-up is an open-moulding composites fabrication process where resin and reinforcements are sprayed onto a reusable mould.
Kayaks made of fiberglass. Fiberglass composite boats have been made since the early 1940s, [20] and many sailing vessels made after 1950 were built using the fiberglass lay-up process. As of 2022, boats continue to be made with fiberglass, though more advanced techniques such as vacuum bag moulding are used in the construction process. [21]
During these sea trials, Fisher found another small flaw in the boats design: it was "wetter than hell." "A lot wetter," he said, "than the other boat had been." The reason for this, according to him, was the 9-inch-wide (23 cm) sole throwing spray into the boat. [1]
The fiberglass spray lay-up process is also used to produce molds, and can provide good filling of corners and cavities where a glass mat or weave may prove to be too stiff. Once the final layers of fiberglass are applied to the mold, the resin is allowed to set up and cure. Wedges are then driven between the plug and the mold in order to ...
Bill Tritt (August 29, 1917 - March 25, 2011) was an American yacht builder. [1] [2]He began working in Glass-reinforced plastic in 1948. He founded Glasspar Corporation in 1949 [3] due to his keen interest in boats and cars and his belief in fiberglass as a material.
Fiberglass seemed the logical construction material, and Otto Bayer of Wizard Boats was enlisted as laminator. The boat was named the Green Dolphin, and four were built in various lengths. This was Tritt's first effort in fiberglass-reinforced plastic (FRP). By 1948 he was building small fiberglass sailing dinghies, and built the first ever ...
