Description
Technical field
The present invention relates to a kind of continuously/long fibre strengthens thermoplastic impregnation mold and using method thereof, belong to continuously/technical field of long fiber reinforced thermoplastic composites preparation.
Background technology
Continuously/long fiber reinforced thermoplastic composites is a kind of fortifying fibre unidirectional array and the length composite identical with the composite pellet.
Continuous fiber obtains long fiber reinforced thermoplastic composites (LFT) after the dipping pelletizing, refer to that specifically length surpasses the fortifying fibre of 8mm (as glass fibre, carbon fiber, aramid fiber etc.) and thermoplastic polymer carries out plastic granule or the goods that fusion is compounded to form.LFT has advantages such as high strength, high rigidity, dimensionally stable, low warpage, antifatigue, anti-creep, can increase substantially the mechanical property of material, have broad application prospects aspect the mechanical property improvement of general-purpose plastics, engineering plastics and special engineering plastics.Continuously/long fibre enhancing technology is one of important engineering that realizes general-purpose plastics, engineering plastics high performance, is subjected to the generally attention of domestic and international scientific research department and industrial quarters in recent years.Not only (mass fraction is 20%～40% to the mechanical property of LFT usually with performance, the content of the performance of thermoplastic polymer, fortifying fibre, can reach 60%) relevant, also and the interface configuration that forms between the fortifying fibre, thermoplastic polymer closely related.In addition, the mechanical property of LFT also keeps length with fortifying fibre close corresponding relation.Compare with the minimum fibre length that is kept in the SFT injection-molded item, the minimum fibre length that is kept in the LFT injection-molded item is big, so the rigidity of LFT, intensity, shock resistance and S. E. A. all are greatly improved.
Because LFT has advantages such as mechanical property, processing characteristics, dimensional stability, cost, and is widely used in automobile, machinery, building, space flight and aviation and high-technology field, particularly the application in automobile day by day increases.The goods that have been widely used in the automobile at present have front end assemblies, bumper, dashboard, instrument board, storage room base plate, door module etc.
In Europe and North America, many auto-parts manufacturer all uses the LFT technology generation to replace original glass mat reinforced thermoplastics (GMT) technology, has become technology with fastest developing speed in the plastics market.
LFT compares with GMT has following good performance:
(1) the mechanical property height of goods, particularly impact strength improve significantly;
(2) goods rigidity and mass ratio height, the distortion little, be particularly conducive to the application of LFT in automobile;
(3) goods toughness improves;
(4) the goods creep-resistant property is good, dimensionally stable;
(5) material superior fatigue resistance;
(6) materials processing performance is good, can be used for forming shape, baroque goods, and GMT can only be used for compression molding, thereby the LFT design freedom is higher than GMT.
Continuously/preparation process of long fiber reinforced thermoplastic composites in the problem of most critical be exactly the dipping and the scattering problem of fiber.Announced at present the impregnating equipment and the impregnation technology of some continuous/long fiber reinforced thermoplastic composites, but some patent does not still solve the dipping and the scattering problem of fiber well, also has a lot of defectives at the mould design aspect.
Patent CN 1037679 discloses a kind of impregnation mold of continuous fiber reinforced thermoplastic composite material, it is characterized in that utilizing a similar sinusoidal crooked dipping runner that fiber is flooded.The resin melt that plasticizing is good is injected the dipping runner from die orifice, and fiber passes the dipping runner under the tension force traction, and at the crest and the trough of curved channel, fiber is subjected to tension force and to the both sides expansion, realizes the dipping of melt to fiber.Though this runner can impregnation of fibers, fiber is actually in runner along crooked raised strip face and floods, and can not well make fiber obtain disperseing.Patent CN 1827671A discloses a kind of improved curved channel impregnation mold, it is characterized in that the crest height in the curved channel is successively decreased from the melt inlet to the outlet, but the problem that still exists is well to make fiber obtain disperseing in the dipping process.Patent CN 101913255A discloses a kind of impregnation mold of continuous fiber reinforced thermoplastic composite material, it is characterized in that at its described installation disk spreader of adjusting on the axle, fiber is disperseed to open under the effect of disk spreader, thereby realize the dipping of fiber, but thermoplastic resin can be detained in the space between disk and the disk in the dipping process, necessary periodic cleaning influences its serialization and produces.
