Connecting structure and connection processing process of web plates of ferry glass reinforced plastic boat

Abstract

The invention relates to processing methods of glass reinforced plastic products, in particular to a connecting structure of web plates of a ferry glass reinforced plastic boat. The connecting structure is characterized in that a glass reinforced plastic bottom plate with a lower web plate is arranged, the lower web plate is perpendicular to the bottom plate, an upper web plate is arranged above the lower web plate, a plastic foam pad layer is arranged between the upper web plate and the lower web plate, and the upper web plate is connected with the lower web plate through connecting plates on two sides. A connection processing process includes the process steps: relatively fixing the upper web plate and the lower web plate connected with the same, pasting bottom connecting plates on two sides of a joint of the upper web plate and the lower web plate respectively by the aid of flexible resin, injecting flexible resin tows by an injection method, pasting the connecting plates on the bottom connecting plates by the aid of flexible resin prior to vacuum pressurization, compacting manually pasted and spread arc-shaped connecting plate layers by the aid of atmospheric pressure and maintaining the pressure until resin curing. The connecting structure has the advantages of high shearing strength, high resistance to tensile load, light weight, good sound insulation and heat insulation effects, practicality, convenience and the like, and is particularly applicable to ferry glass reinforced plastic boats.

Description

[0001] technical field [0002] The invention relates to a processing method of glass fiber reinforced plastic products, in particular to a connection structure and processing technology of webs suitable for manufacturing glass fiber reinforced plastic boats. Background technique [0003] As we all know, minehunters will detonate mines during their missions, which requires the ship to have a strong anti-explosion capability, and one of the keys to the design of FRP minehunters is the design of connection nodes. The first type of connection is the connection of the various parts of the hull itself (hull, deck and bulkhead), and the second type of connection is the connection between the equipment and facilities of the boat and the various parts of the hull. From the material point of view, the first type of connection belongs to the connection between FRP and FRP, and the second type of connection belongs to the connection between FRP and non-FRP (mainly metal, but not exclud...

AI Technical Summary

Problems solved by technology

The connection thickness and connection strength of the above nodes are drawn according to the "Fiberglass Reinforced Plastic Fishery Ship Construction Specification" published by the Fishery Vessel Inspection Bureau of the People's Republic of China "Guoyujianfa 2008] No. 78, and other civil FRP ship construction specifications. The regulations are similar to this, basically the same. Under the action of explosion shock waves, the above-mentioned T-shaped connection nodes are difficult to withstand high-frequency alternating loads, and the compression bending and tension bending are constantly alternated. The connection method of this corner joint node is used On fiberglass ships that require anti-blast capabilities, the joints are very prone to detachment of the bottom plate or web from the corners and breakage at the corners of the corners
