Benefits of technology

[0012] In one aspect, the present invention is a surfboard or similar recreational board for surfing and other water sports which comprises an elongated, shaped core, said core having an upper surface, a lower surface, and a longitudinal axis; a skin or skin layers completely covering said core, at least one skin layer comprising a woven fiberglass fabric having a multiplicity of reinforcing strands woven into said fabric and extending the length of said board parallel to the longitudinal axis, said strands increasing the rigi

Problems solved by technology

However, foam cores alone did not possess enough material strength to maintain the structural integrity of the board for long periods of strenuous use and, consequently, the foam cores required additional structural support which, in some designs, was in the form of wooden stringers to provide the necessary strength for a successful b

Example

[0028] In a typical or representative process of forming a surfboard, the foam core or blank is formed in a large, cement mold roughly the desired shape of the finished surfboard. The mold is constructed in two halves, and the two halves are clamped together and heated. Liquid polyurethane containing a foaming agent is introduced into the mold, the heat initiates the foaming reaction, and a dense, white foam is produced. After the foaming is completed, the mold is opened and the foam core is taken out and allowed to harden. Once the core is hard, it is cut in half vertically from the nose to the tail. A thin wooden stringer is glued between the two halves. The core is then clamped back together to dry. The stringer provides longitudinal stiffness and strengthens the board.

[0029] Next, the outline of the finished board is traced onto the rough core and the outline is cut out with a saw. Starting with the bottom of the core, the surface is smoothed and contoured to its final shape wi...

Abstract

A fiberglass covered recreational board for surfing and other water sports having increased strength and rigidity provided by a longitudinal, central band or bands of higher strength glass fibers such as S Glass and S-2 Glass, or by aramid fibers, or by quartz fibers that are woven into the fiberglass cover as warp threads.

Description

FIELD OF THE INVENTION [0001] This invention relates to surfboards and similar recreational boards for water sports. More particularly, the present invention relates to high strength, lightweight, durable surfboards and to the construction of such surfboards. BACKGROUND OF THE INVENTION [0002] The popularity of surfing and water sports in general has increased significantly in recent decades and includes not only the use of surfboards but also body boards, water skis, and wind-surfing craft. Because of the increased interest, the demand for improved construction has likewise increased. Accordingly, one general object of this invention is to make a lightweight and durable surfboard so that the rider will have a board that lasts longer and will enhance his performance on the waves. [0003] The first surfboards, it is believed, were originated by Polynesians and were made of wood from trees found on their islands. They were carved and shaped by hand and stained and finished with natural...
