The compound loop bonding felt of glass fibre
Technical field
The utility model relates to the compound loop bonding felt of a kind of glass fibre, is used for the reinforcing material of tubing, waterproof building material.
Background technology
At present, many woven fabrics with coating resin, woven roving etc. are as waterproof, reinforcing material in building, pipeline or the various glass fiber reinforced plastic shapes and since woven fabric, woven roving during with various resin-bonded mobile differ from and, wetting-out rate is slow, can cause the consumable quantity of resin to increase accordingly, cost improves; Main is that its hot strength, fatigue durability are relatively poor, and general hot strength can only reach about 220Mpa, and is not easy for glass fiber reinforced plastic surface.
Summary of the invention
The utility model purpose provides a kind of hot strength height, good, the surfacing of fatigue durability, the compound loop bonding felt of glass fibre of being convenient to resin flows and soaking into.
The compound loop bonding felt of this glass fibre comprises woven glass roving fabric braid and glass chopped yarn tiling layer, and two superimposed is compound, and sews up continuous by suture.
Said braid is the two-way woven roving of plain weave that is formed by woven glass roving fabric longitude and latitude weaving, and roving is wherein formed by the Split Down of glass fibre spun yarn.
Glass fiber diameter in the said glass chopped yarn tiling layer is 12 μ m~14 μ m, and length is 12mm~20mm.
Said suture is organic fiber yarn, glass fiber yarn or carbon fiber yarn.
The compound loop bonding felt of this glass fibre whole block material softness, flexible moulding can not produce any buckling stress; Because the gap is few between the fiber, the intensity height, integrally stretching intensity can be the twice of woven fabric; The straight arrangement of roving measuring fiber is convenient to resin flows and is soaked into, the gas enclosure phenomenon in the time of can reducing resin impregnated, and can reduce resin demand, alleviate composite article weight; Interlayer adopts loop bonding compound, and operating procedure is simple, and cost is low.This felt floods unsaturated polyester resin, vinylite, epoxy resin or phenolic resins etc. as reinforcing material and is used for various water-proof section bars such as preparation building, pipeline.
Description of drawings
Fig. 1 is the cross-section structure schematic diagram of this glass fibre stitch combo mat.
Fig. 2 is that the A of Fig. 1 is to topology view.
Among the figure: 1-woven glass roving fabric braid, 1-1-warp-wise Split Down roving, 1-2-broadwise Split Down roving, 2-glass chopped yarn tiling layer, 3-suture.
The specific embodiment
Structure below in conjunction with the compound loop bonding felt of this glass fibre of description of drawings.
As Fig. 1, the compound loop bonding felt of this glass fibre comprises woven glass roving fabric braid 1 and glass chopped yarn tiling layer 2, and two superimposed also sews up continuous by suture 3.
Fig. 2 represents the planar structure of woven glass roving fabric braid 1.Represent among the figure: warp-wise roving 1-1 and broadwise roving 1-2 are formed by the non-twist merging of multiply glass fibre spun yarn respectively, and warp-wise becomes the two-way woven roving of plain weave with broadwise roving such as Fig. 2 weaving, and outward appearance is like woven roving.
Glass fibre spun yarn weak point is cut into the length of 12mm~20mm, evenly is tiled in a side surface of braid, by knit-stitch machine with suture 3 with two-layer sew up continuous, i.e. the compound loop bonding felt of cost glass fibre.
Embodiment
Adopt the woven roving of 600g and the compound loop bonding of glass chopped yarn of 450g to form, mass area ratio is 1050g.
Wherein, the fiber finer yarn diameter 16 μ m of woven roving; Density 2.6 * 2.5; Mass area ratio 600 ± 30g.Glass fiber diameter in the glass chopped layer is 12 μ m, moisture content≤0.1; Length is 12mm, and the omnidirectional woven roving surface that is distributed in.
