Description
Technical field
The present invention relates to Penetrating preparing technical field, refer to a kind of preparation method of abnormally-structured wideband wave transparent bimaleimide resin base antenna house particularly.
Background technology
Polymer matrix composites pressing, with its good feature such as anti-heat-proof quality, low cost, low-density, high strength, is used widely in Aeronautics and Astronautics field.But along with the raising of missile flight speed, too high Aerodynamic Heating is had higher requirement to the anti-heat-barrier material performance of guided missile, in particular for protecting the antenna house of Antenna Operation, need the high temperature of ability more than 450 DEG C.The bimaleimide resin base composite material that heatproof oxidation performance is high, dielectric properties are excellent is one of a few resin-based materials that can be suitable for, and is widely used in the wideband wave transparent products such as wave transparent window, antenna lid, head-shield, antenna house.But bismaleimide monomer moulding process difference (fusing point is high, poorly soluble, the prepreg that quartz fibre increases dipping obtained is stiff, inviscid, solidification temperature is high), usually there is the defects such as poly-glue, Density inhomogeneity, crackle in pressing, product percent of pass is low, at present only, structure simple product little for mold pressing size, and adopt that reserved to add the method for surplus compared with multimachine shaping more, operation is long, and waste of raw materials is serious, the high and unstable product quality of cost.Along with various technical requirement is more and more higher, product profile becomes increasingly complex, and Wall-Thickness Difference is increasing, and during mold pressing, Resin Flow is poor, and pressing lacks material, wedge angle groove gathers that glue is serious, machine adds difficulty increasing etc. and causes pressing qualification rate very low.
Summary of the invention
Technical problem to be solved by this invention is just to provide the dead size forming method of the effective large scale of a kind of finished product, the dimaleoyl imino wave-penetrating composite material antenna house that abnormally-structured, difference in thickness is large.
For solving the problems of the technologies described above, the dead size forming method of a kind of abnormally-structured wideband wave transparent resin-based antenna house provided by the invention, comprises the following steps:
1) meter takes by ratio of weight and the number of copies: the quartz fibre yarn that the resin-based of the bimaleimide resin of 100 parts, the white carbon of 1 ~ 2 part and 60 ~ 85 parts infiltrates; Not, this is a kind of special quartz fibre.
2) resin toughening: add white carbon in bimaleimide resin, mix;
3) prepare premix: the quartz fibre yarn that resin-based infiltrates is immersed in toughness reinforcing after bimaleimide resin in, be squeezed to dipping evenly, then dry, loose, namely prepare premix; Wherein, this premix is made up of the premix of long fibre shape and the premix of short fiber shape;
4) premix is sheared: premix is cut into the premix of long fibre shape and the premix of short fiber shape; Wherein, the premix length of described short fiber shape is 5 ~ 15mm, and the premix length of described long fibre shape is 30 ~ 50mm;
5) preheated mold: use alcohol and cotton by mold cleaning totally, then at mold cavity surface brush coating release agent, by mould and die preheating to 120 ~ 200 DEG C, insulation 10 ~ 30min, makes mould-cavity temperature even;

7) lay the premix bed of material of long fibre shape: the premix of laying long fibre shape on the premix bed of material surface of short fiber shape, matched moulds compacting, repeats to lay compacting 1 ~ 3 time; Form the premix bed of material of long fibre shape, wherein, the premix layer thickness of long fibre shape is from progressive additive under upper, and maximum gauge difference 15mm;
8) clear dimension compression molding: the die with premix is carried out matched moulds, then is 170 ~ 230 DEG C in temperature, pressure is 7 ~ 23MPa condition compacted under, 3 ~ 8h, the demoulding, obtains abnormally-structured wideband wave transparent resin-based antenna house.
Further, described step 3) in, premix content in premix of short fiber shape is no less than 35%.
Again further, described step 6) and 7) in, laying temperature is 60 ~ 100 DEG C.
Again further, described step 8) in, curing molding condition is: be forced into 7 ~ 23MPa after mould being warming up to 140 ~ 160 DEG C with 0.5 ~ 1.5 DEG C/min speed, 20 ~ 40min is incubated after being warming up to 180 ~ 200 DEG C again, then 200 ~ 220 DEG C of insulation 1 ~ 2h are warming up to, cooling pressurize 1 ~ 2h, natural release after being down to 60 DEG C, 220 ~ 240 DEG C of Post RDBMS 220 ~ 260min.
Large scale of the present invention, the quartz fibre that abnormally-structured, difference in thickness is large strengthen bimaleimide resin base composite material dead size forming method, the resin-based adopted infiltrates formulation quartz fibre, improve the adhesion of quartz fibre and resin, improve the mobility of fiber in resin in solidification temperature-rise period, in resin, add white carbon simultaneously, to resin toughening modification, improve the mobility of resin, to solve in compression molding process that mold cavity is complicated, Resin Flow poor being difficult to fill up mould, product is difficult to one-shot forming, the problem that qualification rate is low.Combine the lay mode of " overall lay+local emphasis is filled " simultaneously, outermost layer lay short fiber, short fiber good fluidity, solve the problem that profile complex product wedge angle groove gathers glue, product wall thickness place increases reinforced lay mode can solve large, the loose quality problems of product different wall place density variation, and internal layer lay long fibre can effectively improve product mechanical property.The molded composite material product that the present invention is shaping, each part interior is closely knit, and product relative density difference controls within 5%.Surface quality is good, without defect such as loose, poly-glue, cavity etc., can solve at present because bimaleimide resin moulded manufacturability difference causes the not high problem of its composite dead size molded product qualification rate and large scale, profile complexity, molded product that wall thickness variation is large to be difficult to dead size formation problems.
Beneficial effect of the present invention is:
1) the present invention is specially adapted to shaping bimaleimide resin base composite material, adopt extraordinary quartz fibre and resin toughening modification to improve the special lay mode of long and short fiber of resin forming manufacturability and " overall lay+local emphasis is filled ", solve large scale, profile complexity, the large molded product of wall thickness variation be difficult to one-shot forming problem.
2) the present invention prepares one-shot forming complex profile pressing, adds, decreases operation, decrease raw-material consumption, reduce cost, improve stock utilization and product quality without the need to machine.Simultaneously easy and simple to handle, be convenient to follow-up production in enormous quantities;
3) one-shot forming complex profile, the surface quality of the large pressing of wall thickness variation and the internal soundness prepared of the present invention is good, and qualification rate is high.
