Description
Technical field
The utility model relates to a kind of reinforcing material that is used for fiberglass, is specifically related to a kind of goods of fibre layered thing.
Background technology
Fiberglass is a kind of composite of being made up of reinforcing material and matrix material, claims fiberglass reinforced plastics again, and it has advantages such as light weight, high-strength, anticorrosion, insulation, insulation, sound insulation.The reinforcing material of fiberglass plays skeleton function, and its composition is fiber-like materials such as glass fibre, carbon fiber, boron fibre, aramid fiber, alumina fibre and silicon carbide fibre; The matrix material of fiberglass plays cementation, and its composition is synthetic resin such as epoxy resin, unsaturated polyester resin, phenolic resins.Traditional glass fiber reinforced plastics product is to stick with paste manufactured by hand.This method is ready to the corresponding mould of article shape earlier, on mould, be coated with the last layer releasing agent, cut and the corresponding glass fabric of mold shape, according to certain prescription, auxiliary compositions such as curing agent (comprising crosslinking agent, initator and promoter), colouring agent, filler are transferred in the synthetic resin of glue-like and obtained containing the synthetic resin of auxiliary agent.When pasting, with synthetic resin glass fabric is papered on mould layer by layer up to the requirement that meets thickness, after pruning burr, synthetic resin issues biochemical variation in the effect of curing agent under suitable temperature, gradually the synthetic resin of hardening is bonded together soft glass cloth firmly and finishes up to curing, has then finished the making of goods substantially.But the shortcoming of this method: the one, the materials of synthetic resin are more; The 2nd, the labour intensity height; The 3rd, because the crosslinking agent in the curing agent adopts styrene usually, and styrene is volatile substance, and operator's health is had infringement, also causes atmosphere pollution easily.
As its improvement, a kind of closed moulding method has appearred at present, that is to say, in airtight mould, finished the manufacturing of glass fiber reinforced plastics product.One scheme is to offer groove on the polyurethane foam material of 1.5～2 cm thicks, again glass fabric, polyurethane foam material, glass mat are put into mould successively, under airtight condition, inject the synthetic resin layer that contains auxiliary agent then, then obtain corresponding glass fiber reinforced plastics product after curable synthetic resin is finished.The preparation method of the goods of this fiberglass only is applicable to the goods that wall ratio is thicker, that is to say be subjected to thickness can not be less than 3 centimetres restriction, and the intensity of this goods is lower.
The utility model content
The purpose of this utility model is to overcome the problems referred to above, provide a kind of cost lower, as the fiberglass reinforcing material and fibre layered article composite product that be applicable to fiberglass closed moulding technology.Adopt the glass fiber reinforced plastics product of this fibre layered article composite product as reinforcing material, its thickness is not subjected to can not be less than 3 centimetres restriction, and intensity is stronger.
The technical scheme that realizes the utility model purpose is: a kind of fibre layered article composite product, it is characterized in that: link together and constitute by glass layer, synthetic fibers Nomex and the stacked merging of fortifying fibre, and the synthetic fibers Nomex is positioned in the middle of glass layer and the fortifying fibre layer.
Described fortifying fibre layer is made up of glass fiber warps layer and glass fibre weft layers, and the glass fiber warps layer be positioned at the outside, the glass fibre weft layers is positioned at the inboard; Glass fiber warps layer, glass fibre weft layers, synthetic fibers Nomex and the disposable loop bonding of glass layer and link together; The material of glass fiber warps layer and glass fibre weft layers is woven glass roving fabric.
Described glass layer is short glass fiber layer, glass chopped strand mats, glass fibre continuous felt or glass fibre mat.
The synthetic fibers of synthetic fibers Nomex are polypropylene fibre, polyacrylonitrile fibre, polyester fiber or Fypro.
Described synthetic fibers Nomex is the polypropylene fibre Nomex, and wherein the single fiber diameter of polypropylene fibre is 80～100 μ m, and porosity is 50%～90%.
The material of described fortifying fibre layer is glass fibre warp knitting cloth, aramid fiber cloth or carbon cloth; Glass layer, synthetic fibers Nomex and the disposable loop bonding of fortifying fibre layer and link together.
The thickness of above-mentioned fibre layered article composite product is 2mm～15mm.
The utlity model has positive effect: (1) fibre layered article composite product of the present utility model is with a loop bonding moulding of multilayer material, be suitable for RTM (resin transfer molding technology), VARTM closed moulding technologies such as (vacuum assisted resin transfer molding technologies), has the advantage that designability is strong, technology is simple, work efficiency is high, gained fibre glass product manufacture intensity height, cost are low, particularly improve work situation and reduced labour intensity, because styrene can all enter in the fibre glass product manufacture as crosslinking agent, so eliminated the pollution that atmosphere is produced.(2) synthetic fibers Nomex of the present utility model is a kind of functional layer that plays guide functions, because the synthetic fibers single fiber diameter in this functional layer is bigger, has higher porosity again, not only make the fibre layered article composite product that makes have at a high speed impregnability and water conservancy diversion fast, and make fibre layered article composite product have elasticity and crimpness preferably.This not only can satisfy the requirement of closed moulding technology to water conservancy diversion, and can be so that the maximum ga(u)ge of synthetic fibers Nomex reaches 15mm, thereby when the thicker glass fiber reinforced plastics product of preparation thickness, can save the consumption of resin; Simultaneously because the minimum only 2mm of the thickness of synthetic fibers Nomex can make the glass fiber reinforced plastics product that thickness has only 1 centimetre under the prerequisite of proof strength.(3) with fibre layered article composite product of the present utility model be the fiberglass manufacturing technology of reinforcing material, can be widely used in the manufacturing of generator kuppe, engine room cover, refrigerator car truck board, railway car shell etc. in shipbuilding, wind electricity blade manufacturing, the wind-power electricity generation, and the intensity of these fibre glass product manufactures is higher, anti-shear performance better, can satisfy the requirement of thickness.
