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
Technical field
The present invention relates to the job operation of glass fiber reinforced plastics product, particularly a kind of connection structure and processing technology that is applicable to the web in the glass-reinforced plastic boat manufacturing.
Background technology
As everyone knows, hunt mine sweeper and will ignite submarine mine when executing the task, this just requires naval vessels to have great antiknock ability, and glass-felt plastic to hunt one of key of mine sweeper design be the design of connecting joint.The first kind is connected to hull self each several part, and (connection that ship shell, deck and bulkhead are connected, Equations of The Second Kind are connected to ships and light boats and are connected with ships and light boats body each several part with equipment, facility.From the material angle, the first kind connects and to belong to being connected between glass-felt plastic and the glass-felt plastic, and Equations of The Second Kind connects the connection that belongs to glass-felt plastic and non-glass steel (mainly be metal, but do not get rid of other materials), when using the glass-felt plastic pedestal, also just become being connected between glass-felt plastic and the glass-felt plastic.The designing technique research of these connecting joint, be one of important research task of 863 projects, and T-shaped node is again the principal mode in these connecting joint, T-shaped connecting joint want as shell and deck horizontal, vertical configuration and skewed is arranged, bulkhead generally is vertical configuration and not flat-shaped.
When the ship shell of hunting mine sweeper when glass-felt plastic is subject to the shock wave of untouchable blast under water, large energy upwards can be stated the structure transmission, the T-shaped connecting joint between ship shell and the bulkhead just stand in the breach becomes the significant points of impact.In order to reduce gathering of blast impulse effect, should consider that node has suitable flexibility, consider that again node has sufficient intensity; Should make node under the effect of Blast Load, can produce larger distortion, transferring energy effectively again, its anti-detonating quality will satisfy the general requirement of impact factor 0.66, the T-shaped connecting joint connection structure of glass-reinforced plastic boat as shown in Figure 1 now, the figure Chinese herbal medicine is bottom plating, the 2nd, web, the 3rd, glass chopped strand mats, the 4th, glass fabric, the 5th, resin putty, t

Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose simple, the easy construction of a kind of technique; The node that connects has flexibility, under shock wave high-frequency alternating load action, and connection structure and the processing technology of the glass-reinforced plastic boat web that the ability of its opposing tensile load is strong.
The present invention is to reach by following measure.
A kind of connection structure of glass-reinforced plastic boat web, it is characterized in that being provided with the glass-felt plastic base plate with bottom web, bottom web and base plate are perpendicular, and the bottom web top is provided with epiplastron, be provided with the plastic foam bed course between epiplastron and bottom web, epiplastron is connected with the translateral connecting panel of bottom web.
Epiplastron among the present invention is the plastic foam sandwich plate, namely pastes the glass-felt plastic protective cover at plastic foam core body plate, makes it have lightweight, insulation and sound insulation value is good, low cost and other advantages.
The present invention is filled with the flexible resin synnema in the slit of epiplastron and bottom web junction, to improve Joint strenght and the shock-resistant ability of epiplastron and bottom web.
Processing step of the present invention is:
One, epiplastron is relative with the bottom web that is connected fixing, epiplastron and bottom web are provided with the plastic foam bed course,
Two, adopt flexible resin to paste end connecting panel at epiplastron and both sides, bottom web junction,
Three, adopt injection in the gap that epiplastron, bottom web and plastic foam bed course form, to inject the flexible resin synnema,
Four, adopt flexible resin to paste two-layer at least upper junction plate at low connecting panel, upper junction plate successively shortens,
Five, vacuum pressed, with with the plastic film of air exhaust nozzle with arc connecting panel position good seal, the periphery of plastic film is connected with the periphery of connecting panel, air in arc connecting panel and the plastic film is taken away through air exhaust nozzle with vacuum pump, formed vacuum, it is real to utilize barometric pressure to stick with paste by hand the arc connecting panel lamination that spreads, pressurize is to resin solidification, at last plastic film is removed, to reduce the defective of connecting portion, improve the stability of quality of connection.
The present invention is because the second bonding face of web junction is to bear shearing under the tensile load effect of junction, its shearing strength value is much higher than again normal extension intensity, and the interlayer normal extension intensity in the integrated base plate is much higher than the normal extension intensity of second bonding face, this just makes the ability of the opposing tensile load of junction can be improved again, because the overlap joint laying of junction is used flexible resin, simultaneously on the pad of interstitial position foam, this just makes the junction still have larger " flexibility ", and construction was more convenient when web connected in addition.
