Rowing with superfine fibre and its formation

A technology of super fiber and rowing boats, which is applied in the direction of warships, non-magnetic metal hulls, hulls, etc. It can solve the problems of reducing the rigidity of the hull, poor impact resistance of the hull, discounts on the service life of the rowing boat, etc., and improve the bonding strength. and impact toughness, avoiding high labor intensity and substantial rigidity of the hull

Problems solved by technology

Most of the current rowing boats are made of aramid fiber/carbon fiber and Nomex honeycomb sandwich structure. Due to the limitation of material performance and molding process, its comprehensive performance index is still low, and it cannot meet the requirements of Olympic equipment "lighter, stronger and faster". High standards and high requirements, there are the following defects and deficiencies:
[0003] (1) The contradiction between hull stiffness and hull quality is difficult to solve
Due to the limitations of existing materials, structures and molding processes, it is difficult to achieve the best of both worlds in hull rigidity and hull quality
[0004] (2) Poor impact strength of hull
Especially for rowing boats with full carbon fiber honeycomb structure, they will be damaged if there is a slight bump during transportation, storage, training and competition; and the rowing boats made of this material lack the necessary sense of sports elasticity
[0005] (3) The hull is easy to absorb moisture and increase in weight
Under normal conditions, the weight of the hull will increase by as much as 10% after 1 to 2 years of use; at th...

Abstract

A super-fibrous racing boat has a sandwich structure composed of the external and internal jackets prepared from the pre-dipped poly-p-phenylene benzobisthiazole (PBO) super-fibers and the sandwich prepared from the cellular material Nomex. Its advantages are high specific strength, high specific modulus, high impact strength, high rigidity and light weight.

Example Embodiment

[0020] Examples:
[0021] See figure 1 The structure of the present invention is that the inner end surface 2 and the outer end surface 3 of the Nomex honeycomb sandwich core 1 are respectively bonded with an inner skin 4 and an outer skin 5, and both the inner and outer skins are made of special PBO super fiber prepreg. Glue 6 is formed at the bonding position of the honeycomb sandwich core to improve the bonding strength and impact resistance of the honeycomb sandwich core and the skin.
[0022] The invention adopts the dry forming process, which not only realizes the more accurate calculation in design, but also effectively controls the quality of various raw materials during the blanking and forming construction process, and then achieves the control of the standard quality of the final finished product; and in the blanking, There is basically no pollution during the process of laying and curing. The overall structure of the rowing boat is solidified and formed, which realizes standardization and civilized construction, and ensures the high performance and high quality of the product.
