Problems solved by technology

[0003] In addition, the current assembly method of the horizontal bar and the bar head is relatively simple. The stress and firmness between the horizontal bar and the bar head are also one of the factors that affect safety. Few horizontal bar manufacturers on the market consider this aspect.

Embodiment 1

[0022] Use M40 grade carbon fiber, T700 grade carbon fiber woven cloth with an outer covering surface density of 50-200g / ㎡, and the innermost layer of high toughness material. After molding, the fiber-reinforced thermosetting resin-based composite material round rod 1 and the inner high-toughness material region 4 are produced by pultrusion or molding process, wherein the fiber volume content in the fiber-reinforced thermosetting resin-based composite material round rod 1 is 45%-75%, wherein the circumferential fiber accounts for 0-10% of the total fiber content, and the elastic modulus of the fiber-reinforced thermosetting resin matrix composite rod 1 is between 150GPa-260GPa. Then the fiber-reinforced thermosetting resin-based composite material round rod 1 is subjected to sandblasting, polishing or grinding to roughen the surface, and the surface of the fiber-reinforced thermosetting resin-based composite material round rod 1 is cleaned with a cloth dipped in a solvent, and ...

Embodiment 2

[0024] Use M46 grade carbon fiber, T700 grade carbon fiber woven cloth with an outer covering surface density of 50-200g / ㎡, and the innermost layer is a high-toughness material. In this embodiment, the high-toughness material is preferably aramid fiber. After molding, the fiber-reinforced thermosetting resin-based composite material round rod 1 and its internal high-toughness material area 4 are produced by stretching and winding process, wherein the fiber volume content in the fiber-reinforced thermosetting resin-based composite material round rod 1 is 50% -75%, wherein the circumferential fibers account for 5%-10% of the total fiber content, and the elastic modulus of the fiber-reinforced thermosetting resin matrix composite rod 1 is between 150GPa-260GPa. The fiber-reinforced thermosetting resin-based composite material round rod 1 is roughened by sandblasting, polishing or grinding, etc., and the surface of the fiber-reinforced thermosetting resin-based composite material r...

Embodiment 3

[0026] Use M46 grade carbon fiber, T700SC carbon fiber unidirectional prepreg and high-strength carbon fiber to produce fiber-reinforced thermosetting resin matrix composite rod 1 and its internal high-toughness material area 4, in which high-strength carbon fiber is used as high-toughness material Filled in the high-toughness material area 4, the fiber volume content in the fiber-reinforced thermosetting resin-based composite material round rod 1 made is 75%, wherein the circumferential fibers account for 10% of the total fiber content, and the fiber-reinforced thermosetting resin-based composite material round rod The elastic modulus of 1 is between 150GPa-260GPa. The prepared fiber-reinforced thermosetting resin-based composite material round rod 1 is treated by sandblasting, polishing or grinding to roughen the surface of the fiber-reinforced thermosetting resin-based composite material round rod 1, and the fiber-reinforced thermosetting resin-based composite material is cl...

Abstract

The invention relates to sport equipment and particularly relates to a powder-coated composite material horizontal bar. The powder-coated composite material horizontal bar comprises a lateral bar, thelateral bar orderly comprises a high-toughness material zone, a fiber-reinforced thermosetting resin matrix composite material round bar and a surface functional layer from inside to outside. The high-toughness material zone fills the fiber-reinforced thermosetting resin matrix composite material round bar, is located in the inner layer in the center of the lateral bar and is filled with a high-toughness material. The surface functional layer is bonded to the fiber-reinforced thermosetting resin matrix composite material round bar through a binder and is composed of a wear-resistant material.

Description

technical field [0001] The invention relates to a sports equipment, in particular to a horizontal bar made of powder-coated composite material. Background technique [0002] Most of the current conventional horizontal bars for sports at home and abroad are solid metal round bars. It is difficult to adjust the rigidity and energy-absorbing and shock-absorbing performance of the horizontal bar structure, which is easy to cause damage to the athletes’ joints, and the defects such as inclusions and shrinkage cracks in the metal round bar products are difficult to adjust. Avoid, making the metal round bar in the long-term use process, the cracks caused by these defects are easy to expand, so that the entire horizontal bar structure suddenly breaks, which brings a huge threat to the life and health of athletes. There are also some products on the market that use low-carbon steel chrome-plated to make horizontal bars, but chromium is a toxic metal, and long-term use is harmful to...
