Description
Technical field
The utility model relates to a kind of test bracket, particularly relates to a kind of modified ultra-high molecular weight polyethylene fibre resin and extracts test bracket.
Background technology
Superhigh molecular weight polyethylene fibers is a kind of fiber that the tygon of molecular weight more than 1,000,000 is obtained by gel spinning process, have that intensity is high, modulus is high, crystallinity is high, density is low and the advantage such as good weatherability properties, be widely used in the fields such as military affairs, Aero-Space, naval vessel, ocean, physical culture and protective articles (shellproof, anti-stab, anti-cutting).
Superhigh molecular weight polyethylene fibers has the high degree of orientation and crystallinity, compact structure; Structural unit is the extended-chain configuration of vinyl, and strand arrangement high-sequential; Macromolecular structure does not have polar group, and without chemical activity, surface energy is very low.It is wetting that said structure feature makes superhigh molecular weight polyethylene fibers be difficult to, and not with matrix generation chemical reaction and produce crosslinked, interfacial effect is poor.When superhigh molecular weight polyethylene fibers is used for ballistic area as reinforcing material, poor and cause shock resistance not enough with resin matrix adhesive property, inadequate to the protection of blunt wound.
Due to the inertia of polyethylene molecule, fiber and interlaminar resin are difficult to bonding, and therefore fiber is not easily by resin wetted, have impact on the mechanical property of superhigh molecular weight polyethylene fibers compound substance, the interlayer shear of such as shellproof UD plate, cross directional stretch and fracture property etc.
In order to change the interface inertia that superhigh molecular weight polyethylene fibers causes because of its structure, the method for modification is often adopted to improve the bond effect with resin boundary surface, for improving shock resistance, the ballistic performance of protective materials.Conventional method of modifying has: surface emissivity grafting, cross-linking modified, blending and modifying, filler modified, corona discharge, Cement Composite Treated by Plasma etc.Through modification, the mechanical property of fiber slightly declines, but the adhesive property between fiber and resin matrix obtains larger improvement, makes compound substance have good combination property.
Adhesive property assay method between modified fibre and resin matrix mainly contains: pulling out method, release method, micro-mull technique and section split method etc.Wherein pulling out method is the method for interface performance between conventional mensuration modified fibre and resin matrix, can obtain interface information intuitively.Pulling out method treats resin solidification after normally fiber being imbedded resin matrix, the intensity that test fiber is extracted in resin matrix.
In fiber and resin embedding process, there is no the fibrous framework of a kind of specification and handled easily, cause fibrous bundle to arrange in resin matrix in a jumble, vertically with resin not embed, embed the defects such as error is large.The utility model spy devises a kind of modified ultra-high molecular weight polyethylene fiber monofilament drawing support in resin, make fibrous bundle rule ordered arrangement, vertically embedding is with resin matrix, when using yarn strength machine drawing, fibrous bundle uniform force, improves the accuracy of pull-out strength data.For the interface performance of test fiber (being not only confined to superhigh molecular weight polyethylene fibers) with a certain resin matrix, provide a kind of servicing unit efficiently.
When superhigh molecular weight polyethylene fibers makes compound substance as reinforcing material, often because the chemical inertness of fiber and resin matrix lack necessary cohesiveness, fiber and the gluing interfacial effect of resin very poor, cause composite materials property not reach due index.And when after this fibre modification process, the interface adhesion with resin matrix effectively can be improved, contribute to the mechanical property promoting compound substance.The interfacial bond property of conventional pulling out method inspection modified fibre and resin matrix.But in practical operation, when adopting pulling out method, not have the support of unified, specification regular to imbed resin matrix by neat for fiber, cause test result error larger.
Utility model content
The utility model mainly solves the deficiencies in the prior art, provides a kind of compact conformation, and can imbed in resin by neat for fiber rule, the modified ultra-high molecular weight polyethylene fibre resin that improve test accuracy extracts test bracket.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of modified ultra-high molecular weight polyethylene fibre resin extracts test bracket, comprise back up pad, the two side ends of described back up pad is respectively equipped with test suite, described test suite comprises test platform, described test platform and back up pad fix, the below of described test platform is provided with paper tube, the outer wall of described back up pad is provided with more than one conducting wire pole, described test platform is provided with the resin die of distribution corresponding with conducting wire pole, described paper tube is wound with fiber, described fiber is platform outer wall after tested, conducting wire pole enters in resin die.
As preferably, described conducting wire pole and resin die are upper and lower lineal layout, and the bottom of described back up pad is provided with collet, and described paper tube is located between test platform and collet, and described test platform and back up pad are in vertical distribution.
Therefore, modified ultra-high molecular weight polyethylene fibre resin of the present utility model extracts test bracket, and structure is simple, and usability is outstanding, tests respond well.
