The specific embodiment
are as shown in Figure 1; The novel centre of this kind elongated yarn enhanced fiber composite comprises mylar 3, is inclusive in first fiber-reinforced layer, 2, second elongated fiber-reinforced layer 4 and the 3rd fiber-reinforced layer 5 in the mylar 3, and the described second elongated fiber-reinforced layer 4 is arranged between first fiber-reinforced layer 2 and the 3rd fiber-reinforced layer 5.Described first fiber-reinforced layer 2 and the 3rd fiber-reinforced layer 5 are glass chopped yarn, and length is 5~8cm; The described second elongated fiber-reinforced layer 4 is parallel and the continuous fiber production line direction, and continuous fiber does not evenly have the gap arranges, and on width, every meter novel centre elongated yarn enhanced fiber composite includes 170 elongated yarns; Described mylar 3 is a kind of adjacent benzene type, metaphenylene, p-phenyl's resin, vinylite, epoxy resin one of them or wherein multiple mixture.
As shown in Figure 2, above-mentioned novel centre elongated yarn enhanced fiber process for producing composite materials may further comprise the steps:
Lower floor's polyester carrier film 1 that one, will be wound in the rotating shaft moves to certain orientation with certain speed through the traction of hauling machine 10, is synchronized with the movement with hauling machine 10 free ends;
Two, on lower floor's polyester carrier film 1, lay mylar 3, first fiber-reinforced layer, 2, the second elongated fiber-reinforced layer 4 and the 3rd fiber-reinforced layer 5 successively; Blank after lay accomplishing through soaking into, spreading upper strata polyester carrier film 12 behind the row's bubble, compacting operation, is controlled thickness through plastic squeeze roller 6 then;
three, will pass through novel centre elongated yarn enhanced fiber composite blank behind the plastic squeeze roller 6 and send into and carry out heating for fixing shape in the heating furnace 9.
