Glass steel ship and boat with PP composite board

Abstract

The invention relates to a glass steel ship and boat with a PP composite board. The ship body PP composite board and a function area are included. The function area is arranged on the inner side of the ship body PP composite board. A ship resin mixture layer is arranged on the surface of a honeycomb plate in a brush application manner, and a horsehair roller is utilized for repeated piercing typerolling. The ship resin mixture in the resin mixture layer slowly seeps into the honeycomb plate through liquid permeating holes till curing is complete and a firm inner structure is formed. A curingagent is contained in a liquid inlet pipe and seeps into various structure layers through seepage holes, the structure of the ship body PP composite board is more stable, the structure strength is high, the surface of the completely-cured PP composite board is ground, burrs are removed, the surface smoothness is improved, and practicability is improved. According to different design requirements,the thickness for manufacturing a glass fiber layer and the filling amount of resin into a filling cavity are flexibly selected, different ship and boat design requirements are met. The glass steel ship and boat with the PP composite board is small in weight, high in weather resisting performance and high in cost performance and structure strength.

Description

technical field [0001] The invention relates to the technical field of fiberglass boat manufacturing, in particular to a fiberglass boat with a PP composite board. Background technique [0002] FRP is a new type of shipbuilding material and an important part of the modern material revolution. FRP has not been used in the shipbuilding industry for a long time, but it has highlighted its strong vitality and broad development prospects. The characteristics of FRP ships are quality Light, high strength, great potential for weight reduction, suitable for high-performance ships and rowing boats with limited weight; corrosion-resistant, anti-water biofouling, more suitable for use than traditional shipbuilding materials; non-magnetic, so it is a minesweeper, The best structural and functional material for minehunting boats; good dielectric properties and microwave penetration, suitable for warships; can absorb high energy, good impact toughness, ships are not easily damaged by coll...

[0002] FRP is a new type of shipbuilding material and an important part of the modern material revolution. FRP has not been used in the shipbuilding industry for a long time, but it has highlighted its strong vitality and broad development prospects. The characteristics of FRP ships are quality Light, high strength, great potential for weight reduction, suitable for high-performance ships and rowing boats with limited weight; corrosion-resistant, anti-water biofouling, more suitable for use than traditional shipbuilding materials; non-magnetic, so it is a minesweeper, The best structural and functional material for minehunting boats; good dielectric properties and microwave penetration, suitable for warships; can absorb high energy, good impact toughness, ships are not easily damaged by collisions and extrusions; low thermal conductivity, insulation Good thermal performance, suitable for building fire-resistant lifeboats, fishing boats and refrigerated ships, etc.; the surface of the hull can be mirror-smooth, and can have various colors, especially suitable for building various yachts with beautiful appearance; good designability, can be customized according to the ship structure According to the different requirements of the components, the optimized design can be realized through material selection, layup research and structural modeling; the integrity is good, the hull has no seams and gaps, and it can prevent leakage; the forming is simple, labor-saving compared with steel and wood, and mass production is special Well, the potential for cost reduction is great; it is easy to maintain, the maintenance cost is much less than that of boats made of other materials, and the economic performance of the whole life cycle is good. , poor weather resistance, low cost performance and low structural strength
