Problems solved by technology

[0006] The invention provides a method for improving the wear resistance of the bottom of the FRP assault boat, which can overcome the existing disadvantages of increasing the weight of the boat body and deteriorating the molded line, and solves the problem of contact between the bottom of the assault boat and the beach or underwater obstacles. For the problem of damage to the boat body caused by friction or impact, according to the special requirements of adding a wear-resistant layer to the assault boat, optimize the material, structural form and process method of the wear-resistant layer to reduce the impact of modification on the shape line and sailing performance of the assault boat , the technical effect of improving the damage resistance and safety and reliability of the assault boat

Embodiment

[0064] The factory processes and manufactures wear-resistant profiles of ultra-high molecular weight polyethylene wear-resistant modified composite materials with different structural types according to the bottom profile of the assault boat's easy-to-wear parts, and provides them to users; Purification treatment, and then use epoxy structural adhesive and bonding process to paste the wear-resistant profile on the designated part of the bottom of the assault boat, and after solidification, it will be trimmed by grinding and scraping to complete the wear-resistant modification of the bottom of the assault boat.

[0065] The ultra-high molecular weight polyethylene wear-resistant modified composite material is composed of the following components:

[0066] Ultra-high molecular weight polyethylene substrate

[0067] 1% to 2% carbon fiber (short fiber and long fiber each 50%);

[0068] Domestic PE toughening agent with 5% to 6% of substrate quality;

[0069] 8% to 10% NDZ-105 ti...

Abstract

The invention discloses a process for improving boat bottom wear resistance of a glass steel assault boat. A superhigh molecular weight polyethylene wear-resistant modified composite material is manufactured into a wear-resistant block material close to a boat bottom line through compression moulding and then is subjected to secondary modification; and the wear-resistant material is adhered to easily-worn parts at the bottom of the assault boat by an epoxy structural adhesive to form a boat bottom wear-resistant layer. By the process, the wear-resistant material has high wear resistance, small frictional coefficient and high structural strength; the adhering process is reliable and convenient in mounting; influence on properties, such as molded line, navigation and the like, of the assault boat caused by modification can be effectively reduced; damage resistance, safety and reliability of the assault boat are improved; the modification process is simplified; maintenance cost is reduced; and service life of the assault boat is prolonged.

Description

technical field [0001] The invention belongs to the technical field of ship building and relates to a method for improving the wear resistance of the bottom of a ship, in particular to a process for improving the wear resistance of the bottom of a FRP assault boat. Background technique [0002] In wars, assault boats, which are shallow, light, high-strength, and high-speed mobile water mobile support equipment, are frequently responsible for quickly transporting combat personnel and materials from water to shore, overcoming obstacles in rivers, and carrying out assaults or attacks on the shore. The task is to seize and consolidate waterfront beachheads and ensure important support equipment for combat victory; in non-combat operations such as flood fighting and rescue, assault boats are regarded as "boats of life", and are used in rescuing people in distress, transporting disaster relief materials, and Rescue command and other aspects play a very important role.
