Description
Technical field
The utility model relates to a kind of novel bar pin assembling type glass-fiber reinforced plastic grille sheet material.
Background technique
Glass fibre reinforced plastics another name glass fiber reinforced plastic, is commonly called as FRP(Fiber Reinforced Plastics), i.e. fibre-reinforced plastics.Fiber difference according to adopting is divided into glass fiber reinforced composite plastics (GFRP), fibre reinforced composite plastic (CFRP), and boron fiber strengthens composite plastic etc.
It as reinforcing material, makes a kind of composite material of body material using glass fibre and goods (glass cloth, band, felt, yarn etc.) thereof with synthetic resin.Fibre reinforced composites are made up of reinforcing fiber and matrix.The diameter of fiber (or whisker) is very little, and generally below 10 μm, defect is less less again, and fracture strain is about within 30/1000ths, is brittle material, easy damaged, ruptures and is corroded.Matrix phase is for fiber, and intensity, modulus are all much lower, but can withstand large strain, often has viscoelasticity and elastoplasticity, is toughness material.
Because used resin variety is different, therefore there is the title of organic toughened glass, fiber glass epoxy, phenolic fiberglass reinforced plastics.Light weight and hard, non-conductive, mechanical strength is high, recycles few, corrosion-resistant.Steel manufacturing machine part and automobile, ship housing etc. can be replaced.
The advantage of glass fibre reinforced plastics is: high-strength light.Relative density, between 1.5 ~ 2.0, only have 1/4 ~ 1/5 of carbon steel, but tensile strength is close, even exceedes carbon steel, and specific strength can compared with high-grade alloy steel.Therefore, at aviation, rocket, astrovehicle, high-pressure bottle and need to alleviate in the product application of deadweight at other, all there is remarkable effect.The stretching of some epoxy FRP, bending and compression strength all can reach more than 400Mpa.Corrosion-resistant.FRP is good anticorrosive material, has good resistivity to the acid of air, water and general concentration, alkali, salt and multiple oils and solvent.Be applied to the All aspects of of chemical anticorrosion, replace carbon steel, stainless steel, timber, non-ferrous metal etc.Good electrical property.Be excellent insulating material, be used for manufacturing insulator.Still good dielectricity can be protected under high frequency.Microwave transparent is good, is widely used in radome.Thermal characteristics is good.FRP thermal conductivity is low, is 1.25 ~ 1.67kJ/(mhK under room temperature), only having 1/100 ~ 1/1000 of metal, is excellent thermoinsulation material.In instantaneous superhigh temperature situation, be desirable thermal protection and ablation resistant material, astrovehicle can be protected more than 2000 DEG C to bear washing away of high velocity air.Designability is good.(1) as required, various infrastructure product can be designed neatly, meet usage requirement, product can be made to have good integrity.(2) fully can meet the performance of product by selection material, as: can corrosion resistant be designed, resistance to TRANSIENT HIGH TEMPERATURE, product direction has special high strength, dielectricity is good, etc.Manufacturability is excellent.(1) moulding process can be selected neatly according to the shape of product, technical requirements, purposes and quantity.(2) technique is simple, can once-through, and economic effect is given prominence to, especially few to quantity that is complex-shaped, not easy-formation product, its technique superiority more outstanding.
The shortcoming of glass fibre reinforced plastics is: Young's modulus is low.The large twice of modular ratio timber of FRP, but less than steel (E=2.1E5) 10 times, in product structure, therefore often feel that rigidity is not enough, be easily out of shape.Thin-shell construction, sandwich structure can be made, also by high modulus fibre or do the forms such as stiffening rib to make up.Long-term temperature tolerance is poor.General FRP can not at high temperature Long-Time Service, and general purpose polyester FRP intensity more than 50 DEG C just obviously declines, general only use 100 DEG C below; Universal epoxy FRP is more than 60 DEG C, and intensity has obvious decline.But can fire resistant resin be selected, make Long-term service temperature be possible at 200 ~ 300 DEG C.Deterioration phenomenon.Deterioration phenomenon is the common defects of plastics, and FRP is no exception, under the effects such as ultraviolet, dust storm sleet, chemical mediator, mechanical stress, easily cause hydraulic performance decline.Shear strength is low.Interlaminar shearing strength is born by resin, so very low.Can, by selecting technique, using the methods such as coupling agent to improve interlayer adhesion, most importantly when product specification, avoid interlayer is cut as far as possible.The production method of glass fibre reinforced plastics divides two large class, i.e. wet method contact type and dry method compression and moulding substantially.As divided by process characteristic, there is hand pasting forming, laminated into type, RTM method, ironing, compression molding, Wrapping formed etc.Hand pasting forming comprises again hand and sticks with paste method, pressure bag method, gunite, wet paste low-pressure process and stick with paste method without mould hand.
Model utility content
The purpose of this utility model, is to overcome above-mentioned limitation, thus provides a kind of novel structure, and be convenient to transport, safety coefficient high cost is low, and working efficiency is high, non-damageable one novel bar pin assembling type glass-fiber reinforced plastic grille sheet material.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel bar pin assembling type glass-fiber reinforced plastic grille sheet material, comprise upper plate and lower plate, described upper plate and lower plate are provided with multiple square through hole and form grid, described upper plate upper surface is provided with multiple groove, described lower plate lower surface is provided with multiple disc slots, described upper plate is connected by bar with lower plate, described bar is provided with screw thread near upper plate lower surface one end, described screw thread is furnished with nut, described bar two ends are provided with nut, and described upper plate and lower plate corner are equipped with bolt hole.
