Abstract
The invention discloses a composite glass fiber material with a mixed reinforced form. Multiple layers of glass fiber grid cloth and glass fiber braided fabric are soaked with thermosetting resin, semi-solidified and pressed to form the composite glass fiber material with the mixed reinforced form. Short-cut glass fibers are mixed into the thermosetting resin. The glass fiber braided fabric is introduced in terms of the composite material to reduce cost of the composite material and meanwhile, the short-cut glass fibers are introduced into the surface of each layer of glass fiber braided fabric and bonding force between layers is reinforced when the multiple layers of the glass fiber braided fabric are stacked. Glass fiber sewing threads are used for sewing the multiple layers of the glass fiber braided fabric to form a three-dimension composite structure. The shear strength and the tensile strength of the composite material are improved.
Description
Technical field
The present invention relates generally to the glass fiber compound material field.
Background technology
At special occasions, the footwear that people wear need to add a toe-cap with higher mechanical strength, with the safety of pin front end in the protection walking process.Safety toes adopts the metal toe-cap at present, but the metal toe-cap is heavier, and with vamp upper layer, is combined bad.Therefore there is the composite of employing to make safety toes.As the composite that uses the glass woven roving to strengthen, but the glass woven roving is expensive, so cost performance is low is difficult to be accepted by market.Even adopt the glass fibre woven roving, but have between each layer glass fibre woven roving, lack fiber and connect, so the shear strength of composite and anti-bending strength low, the stamping press that makes toe-cap to bear is less.In addition, because there is many longitudes and latitudes intertwined point in woven roving, resin viscosity is larger simultaneously, and intertwined point is difficult to be infiltrated by resin, and exposed glass fibre is wear-resisting and folding strength is low.
Summary of the invention
Goal of the invention: for the problem and shortage of above-mentioned existing existence, the purpose of this invention is to provide a kind of composite glass fiber material that strengthens form and safety toes of preparation thereof of mixing, it is anti-shearing and bend resistance intensity is large, and cost is low.
Technical scheme: for achieving the above object, the present invention by the following technical solutions: a kind of composite glass fiber material that strengthens form that mixes, is then formed by semi-solid preparation pressing by multilayer glass woven roving and glass braid after the heat of emersion thermosetting resin; In wherein said thermosetting resin, be mixed with short glass fiber.
Described glass woven roving and glass braid by glass fiber sewing thread, be stitched into one between layers.
The weight sum of described glass woven roving, glass braid, glass fiber sewing thread and short glass fiber accounts for 50～70% of composite glass fiber material gross weight.。
Meridian between the adjacent two layers of described glass woven roving and glass braid with an angle.
Meridian between the adjacent two layers of described glass woven roving and glass braid has equal angle, and this angle is 30 ° or 45 °.
In thermosetting resin, the weight content of short glass fiber is 3～10%.
Described glass woven roving, glass braid, glass fiber sewing thread and short glass fiber are the E glass fibre.
Another purpose of the present invention has been to provide a kind of above-mentioned composite glass fiber material and has made the safety toes of preparation, by multilayer glass woven roving and glass braid after the thermosetting resin that contains short glass fiber infiltrates, after semi-solid preparation processing and cutting, be superimposed together, then by glass fiber sewing thread by every layered suture integrator, and heating in mould, pressurization form safety toes.
Beneficial effect: compared with prior art, the present invention has the following advantages: when composite of the present invention is introduced glass braid reduction composite cost, on every layer of glass fabric surface, introduce short glass fiber, made the adhesion that has strengthened interlayer when laying; Utilize simultaneously glass fiber sewing thread to make the formation three dimensional composite structure to multilayer glass braid, improved shear strength and the tensile strength of composite.
The specific embodiment
Below in conjunction with specific embodiment, further illustrate the present invention, should understand these embodiment only is not used in and limits the scope of the invention be used to the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
Mixing of the present invention strengthens the composite glass fiber material of form and by glass fiber sewing thread, makes simultaneously by the introducing short glass fiber of the surface in glass grid layer of cloth and glass braid layer, thereby making when Multi-stacking compaction chopped strand be distributed in interlayer forms distributed in three dimensions and has improved the stress transmission, stress when the minimizing composite is subjected to External Force Acting is concentrated, and the distributed in three dimensions mode has improved the shear strength of interlayer simultaneously.Glass braid Partial Replacement glass woven roving can reduce the cost of material in addition.
In epoxy resin solution, adding specification is the short glass fiber of 2～3mm, and addition is 5%, and carries out agitation as appropriate.Then E glass woven roving and E glass braid are carried out to pre-preg in above-mentioned mixed solution, dry and make it reach primary solidification (reaching the B stage), guarantee that glass, by the resin complete wetting, does not exist interweave white point and bubble, then with plastic sheeting, coat stand-by.Then the prepreg fabric of the above-mentioned E of containing short glass fiber is carried out to cutting, laying, then make the all-in-one-piece three-dimensional structure with glass fiber sewing thread.And be placed in the toe-cap particular manufacturing craft, pressurized, heated production obtains the safety toes that anti-shear performance is higher.Glass woven roving, glass braid, glass fiber sewing thread and short glass fiber all belong to glass fiber reinforced materials in process of production, and their specific gravity control in composite are good 50～70%.In addition when carrying out laying, E glass woven roving and E glass braid are adopted to alternately appearance, and the meridian of the relatively front one deck of later layer staggers 45 °, thereby make graticule between layers be tension and the shear strength that staggered promiscuous mode can improve composite.
