Appeared in last few years a variety of is aimed at successive fiber increases high-powered beforehand the macerate method that dip expects, have melt dipping process, solution dipping process, pulverous vulcanization dipping process, pulverous suspension dipping process commonly, mix standard of work out equipment to wait. 1. Foreign technology develops a condition

Abroad increases to successive fiber high-powered beforehand the research that dip expects starts earlier, already was in industrialized stage of production at present, at present PEEK beforehand dip expects main supplier has TenCate, Fiberforge, Victrex, Celanese and Dong Bangte to be able to bear or endure gram silk, PPS beforehand dip expects main supplier has TenCate, Fiberforge. Company of industry of British empire chemistry (Imperial Chemical Industries Ltd, abbreviate is ICI) the company carries melt dipping process, develop in succession since 1982 gave the carbon fiber such as APC-1 and APC-2 / get together ether aether ketone is one-way composite material beforehand dip makings; American Ticona (Celanese) the company uses melt dipping process, preparation high-powered one-way and successive fiber increases thermoplastic composite material beforehand dip makings, equipment is shown 1 times like the graph. German Augstin used preparation of success of pulverous suspension dipping process to go out thermoplastic beforehand dip belt. Its produce speed to be 5m/min, beforehand the fiber bulk content that dip takes is 60% . Additional, BASF company of France also used preparation of this macerate method to go out thermoplastic product of carbon fiber composite material. Dutch Tencate and France.

Graph company of Atochem of 　 of 　 of craft of 1 melt macerate uses pulverous liquefaction dipping process to undertake powder beforehand dip silk bundle preparation, first carbon fiber silk bundle spreading is exhibited thin; Was full of the fluid-bed of the tiny powder of 10μm through next, make colophony powder besmears Fu is in equably fiber surface; Colophony film package uses his after, get lapping having the fasciculus of colophony powder, namely pulverous beforehand dip silk bundle (Powder Impregnated Bundles) , this kind beforehand dip silk bundle texture is soft, can braid all sorts of fabric, after via overmuch layer the shop is stuck into fixed appearance, add lukewarm pressurization to be able to make composite material, use very convenient. The fiber that American NASA invents is mixed invent a technology, will thermoplastic colophony machines imperceptible fiber, mix its and carbon fiber the work out to raise colophony and fiber wellability into fabric next, if pursue,2 are shown. Graph 2 mix make up beforehand dip makings reachs his to shape craft 　 　 2. Country of 　 of state of affairs of domestic technology development increases to successive fiber high-powered thermoplastic composite material beforehand the research of technology of dip makings preparation just starts, at present industrialization is: Fibre glass enhances PP thermoplastic composite material beforehand dip belt, had reached the application on car of box type freight in house car, cold storage car, container. Achievement of domestic other research has: The person such as Xian Guijun developed a macerate successive fiber is thermoplastic beforehand the small-sized test facilities that dip takes. This device uses mechanical roller to make fiber silk bundle spreading, macerate means is melt macerate, reach colophony content is after 40% ? The successive carbon fiber of 70% beforehand dip belt and successive fibre glass beforehand dip belt. The person such as Chen Ping uses solution dipping process, macerate of solution of research PPESK colophony all sorts of fibrous processes, analyse the different parameter effect to macerate effect and composite material function; In the suspension liquid that the person such as Rao Jun expects macerate of successive carbon fiber in PPS pink and ketone of 2 benzene aether mixes and becomes, preparation gave performance advantageous beforehand dip makings; Zhang Yi decides the PPS slop that waits to the person mixes PPS and water and become suspension fluid state, come with this macerate is successive fiber, preparation is thermoplastic beforehand dip makings. The person such as Zhou Xiaodong studied the pulverous macerate process of successive fibre glass, conclusion shows, pulverous macerate effect is reduced as pulverous bead diameter or roller amount increases and increase; Zhang Feng breaks up etc use pulverous liquefaction dipping process, fiber silk bundle preparation is become thermoplastic beforehand dip belt, built a preparation thermoplastic beforehand the test facilities that dip takes. 3. What the 3.1 home of 　 of technical craft 　 of industrialization commercialize is thermoplastic beforehand the preparation method of industrialization of home of 　 of circumstance of dip material progress is to shed fine of Bo of the preparation that extend a law to enhance PP, PA, PC, PE to wait thermoplastic resinous beforehand dip belt, at present also partial manufacturer makes carbolic a rope for towing a boat beforehand of dip PA or PEEK beforehand dip makings, but be controlled to apply a reason to do not have batch application downstream. Nowadays applies in the market wide is Bo fine PP beforehand dip makings, main volume of home produces manufacturer to have strange one, Pisces, outstanding thing outstanding, Sui gold, China get together, handsome Er, golden hair, extremely power wait. What 3.2 abroad commercialize is thermoplastic beforehand dip makings makes progress circumstance
