Description

The forming method of batten fiber reinforced plastic composite engineering material pultruded by wood-fiber glass and goods
The invention belongs to the fiber hybrid composite production technical field, particularly wood fibre bar (wood is slightd bar or wood chip or the like) and glass fibre etc. are cooperated to strengthen the forming method that various prismatic linear batten glass fiber reinforced plastic composite engineering materials and goods are made in the thermosetting resin pultrusion.
At present, the pultrude process of known fibre glass roving is a kind of method of continuous producd fibers reinforced plastic section bar.It is the non-twist fibre glass roving on the creel to be carried out resin with other continuous reinforcing material, surface of polyester felt etc. soak achievement, then by keeping shaper, the shaping die of definite shape, and make it in mould, be pulled continuous depanning behind the solidifying, through cutting off a kind of automatic production process that can obtain the glass fibre reinforced plastics pultrusion product.Various glass fibre reinforced plastics pultrusion product performance are good, have wide range of applications, but cost are too high, and the application scale is not very big.The densification of hard miscellaneous tree equipment structure, resistance to compression, tension, wear-resisting property are good, and the specific humidity rate that rises is less mutually with other vegetable fiber except that bamboo material, and its corrosion resistance more is better than other vegetable fibers such as softwood.Timber is renewable raw materials, compares cheaply with other man-made fibre material, produces the usage requirement that various drawing and extruding section bar products can satisfy many occasions with good wood materials.But because timber length, diameter are limited, directly become the flexible distortion forfeiture of plate usability, isolating property, to compare weather resistance poor with plastics or glass fibre reinforced plastics series products under the nature, directly with the compound compatibility performance difference of various fluoropolymer resins or the like multiple reason, make it fail to use on the pultrusion product, therefore a large amount of wood materials fails to bring into play its due effect.
In order to overcome the deficiency of short and small or the like the shortcoming of the high and wood materials of existing glass fibre reinforced plastics pultrusion product price, batten fiber reinforced plastic composite engineering material pultruded by wood-fiber glass product provided by the invention, it is little that this batten glass fiber reinforced plastic composite engineering material product can not only guarantee to make full use of hard miscellaneous tree material contour projector, the proper property that tensile strength parallel to grain and parallel-to-grain compressive strength are good, and have the outward appearance and a performance of glass fibre reinforced plastic material, permeability with glass fibre reinforced plastics under the situation about needing also can make it to have the outward appearance that manifests wood materials, utilize the coating skin of glass fibre reinforced plastic material to intercept wood materials and air simultaneously, unfavorable and hostile environments such as mould, the contact of material, therefore can be under the prerequisite of the original performance that guarantees wood materials, prolonged working life widely, also be easy to simultaneously by increasing, the content that reduces glass fibre improves, reduce glass fibre reinforced plastics content and control the performance and the price of batten fibre glass product manufacture, can satisfy the usage requirement of many applications, also be better than glass fibre reinforced plastics as heat-shielding performance etc., the particularly reduction of price can realize large-scale promotion application.
The technical solution adopted for the present invention to solve the technical problems is: the wood fibre bar that at first Wood Processing is become all size that needs by design, in advance the limited long lignocellulose bar of same specification cross section through butt joint, finger, play splicing such as groove overlap joint, lining felt, lining paper, lining cloth or mechanical coupling becomes the continuous wood fibre bar of endless, be called for short continuous batten, the batten coiling is called for short the batten volume continuously.Next the wood that as required batten of multireel same size or different size volume is placed on the fiber frame is rolled up on the frame, corresponding with every batten as required a volume or multireel woven glass roving fabric be placed on the fiber frame with the corresponding creel of this batten on, other roving volume, glass fiber mat, glasscloth or the like other reinforcing material is placed on the fiber frame on corresponding yarn, felt, the fabric frame, draw various reinforcing fibers such as batten, rove, felt, fabric by organiser, as required by the dehumidifying of dehumidifying heater, heating.Enter steeping vat preimpregnation achievement resin, the reinforcing material that preimpregnation is good (batten, rove, felt, fabric or the like) passes pre-setting device, mould or device with the mould pre-setting, it with batten, rove, felt, fabric etc. accurately in conjunction with, remove the bubble in unnecessary resin, the eliminating system.Then enter the continuous batten glass fibre reinforced plastics pultrusion product that the forming and hardening mold heated with multistage heating function is solidified into required sectional shape, this product deflects from mould under the traction of traction gear, after the cutting device fixed length cutting becomes the batten glass fibre reinforced plastics pultrusion product of Len req.Pultrusion batten fibre glass product manufacture can be solid also can be hollow, the batten glass fibre reinforced plastics drawing and extruding section bar that can be all size also can be various not specification batten glass fibre reinforced plastics pultrusion profile shapes; Solid, the hollow plate of batten glass fibre reinforced plastics pultrusion; Batten glass fibre reinforced plastics pultrusion circular pipe, the pultrusion of batten glass fibre reinforced plastics is square, rectangle tubing; Batten glass fibre reinforced plastics pultrusion empty stomach, real abdomen door and window profile material; Batten glass fibre reinforced plastics pultrusion hollow, sandwich and real core vertical axis wind generator blade; By cooperate also solid, the hollow various non-linear batten fibre glass product manufacture that can pultrusion goes out various iso-cross-sections rotations or curve with mould.
The invention has the beneficial effects as follows, the various pultrusion batten fibre glass product manufactures that go out by this processes can enlarge the application area and the application of wood materials widely, can guarantee that wood materials given play to huge usefulness, adopted by the coating of glass fiber mat, fabric etc. by batten and glass fiber yarn and to have reduced isolating property, simultaneously also increased compatibility with fluoropolymer resin by glass fiber yarn, realize can leaning between the batten mechanical connection of glass fiber yarn and resin, this has eliminated batten and the compound segregative disadvantage of polymeric matrix.Can determine or not non-twist glass fiber yarn, felt, fabric to wait around single batten, many battens, whole batten and fibers according to usage requirement rotates, what are around amount, can require to design the batten glass fibre reinforced plastics pultrusion product of various structural styles and wooden glass ratio according to usability around the few good product performance of the big batten surface exposure amount of amount, and improve wooden glass ratio as far as possible to reduce the demand that cost satisfies large-scale application.Wood glass Wella squeezes material and compares with wood glass fabric pultrusion product to have reduced and weave link and shortened technological process, therefore has the low advantage of cost.
