Abstract
An extremely light-weight racing paddle is disclosed which is formed of a very light-weight core of low structural strength surrounded by a shell formed of an extremely strong, light-weight fibrous material which supplies structural strength to the core material. The thickness of the fibrous material is varied along the shaft of the paddle so as to be thickest in the regions of highest stress. The blade of the paddle is reinforced by a selected pattern of fiber strips. Various embodiments of the basic paddle structure are disclosed, as is the method of making the paddle.
Claims9
An extremely light-weight racing paddle comprising:
- a core shaft formed of a very light-weight, easily shaped material,
- a core blade, also formed of a very light-weight and easily shaped material, secured to said core shaft, to form a paddle core structure,
- an external shell formed of hardened light-weight filamentary material molded around and bonded to said core shaft for providing an external structural reinforcement thereof,
- said external shell including continuous layers of said hardened light-weight filamentary material which overlap said core shaft and said core blade;
- and,
- a pattern of reinforcing strips of hardened light-weight filamentary material bonded to said core blade for providing an external structural reinforcement thereof,
- whereby an extremely light-weight, high-strength racing paddle is formed in the shape of said light-weight paddle core structure.
A method of making an extremely light-weight racing paddle, comprising the steps of:
- forming a core shaft of a very light-weight material,
- forming a core blade of a very light-weight material,
- securing said core blade to said core shaft to form a core paddle structure,
- coating said core paddle structure with a layer of resin for waterproofing said core,
- sequentially applying carbon fiber tows along said core shaft and said core blade to form an external shell such that said carbon fiber tows overlap said core shaft and said core blade, and coating said carbon fiber tows with hardening resin.
