The so-called ultra-thin thermoplastic fiber reinforced composite material in the present invention is mainly a prepreg composite sheet or a composite plate, and the material includes carbon fiber, glass fiber, and the like, and the fibers suitable for the molding process do not exceed the scope disclosed in the present invention.

Please refer to FIG. 1a, a molding apparatus for a very thin thermoplastic fiber reinforced composite material according to the present invention. The first preferred embodiment according to the process sequence includes at least: a yarn spreading module 70 and a hot pressing module 100. A full-bundle arranging device X is provided in front of and / or behind the yarn spreading module 70.

Please refer to FIG. 1b, another embodiment of the present invention is under the setting of the yarn spreading cloth module 70, the hot pressing module 100, and the whole bundle arranging device X of the first preferred embodiment. A yarn bundle tension control module 20 is arranged in front of the yarn spreading cloth module 70, or a yarn bundle processing module 40 is set in front of and / or after the yarn spreading cloth module 70, or the hot pressing module After 100, a winding device 110 is provided to enhance the effect of regulating the yarn spreading and the impregnation of the thermoplastic resin according to the present invention.

The manufacturing equipment of the ultra-thin thermoplastic fiber reinforced composite material S of the present invention is a continuous process equipment. The following describes the setting and using methods of the aforementioned modules or devices, respectively.

Please refer to FIG. 1 b. First, the yarn bundle tension control module 20 includes a creel 21 and a plurality of tension control brackets 22. The tension control bracket 22 is disposed on the creel 20. In addition to being fixed on the top, the bundle 10 also has the function of monitoring and controlling the tension of the yarn bundle; a specific and preferred implementation method is that the yarn bundle 10 is first wound on a bobbin, which is a hollow columnar shape and can be tightly packed. It is sleeved on the tension control bracket 22 and linked with it, so that the yarn cone wound with the yarn bundle 10 can adjust the tension effect of the yarn bundle 10 with the degree of resistance given by the tension control bracket 22; The yarn bundle 10 is composed of a plurality of fiber yarns. The yarn bundle 10 used in this embodiment is a carbon fiber yarn bundle, but other yarn bundles that can be made into a board can also be used, such as glass fiber yarn bundles; The tension control bracket 22 provides a tension monitoring method by setting a tension sensor, and the tension regulation method can be provided with an electric motor in the tension control bracket 22, which automatically rotates the tension control bracket 22 through the electric motor and links the yarn. To increase or decrease the The degree of tightening or roll beam 10 put sheets, tension control to achieve the effect, in addition to the motor control, may manually adjust the tension, it is not limited thereto. The yarn bundle tension control module 20 needs the function of tension control. The main reason is that the different angles that the yarn bundle 10 enters in subsequent processes will cause tension differences. At this time, the yarn bundle tension control module 20 can be adjusted accordingly. The tension degree of each of the plurality of yarn bundles 10 is made uniform, so that each fiber yarn in the yarn bundle 10 is unfolded to obtain a relatively even yarn spreading effect, but the yarn bundle tension control of the present invention When the module 20 is the device provided by the present invention, it is only necessary to set correspondingly if there is a need to regulate the tension of the yarn bundle, and it is not intended to limit the device of the present invention to include the yarn bundle tension control module 20.

Please refer to FIG. 2a to FIG. 2b. The yarn spreading module 70 of the present invention is provided with an accommodating slot 71, a plurality of yarn spreading guides 73, and a plurality of air inlet holes 75. The yarn spreading guides 73 are provided. On the side groove wall of the accommodating groove 71, the air inlet hole 75 is provided at the bottom of the accommodating groove 71. The accommodating groove 71 contains a thermoplastic rubber powder H therein.

Please refer to FIG. 2b. The air inlet hole 75 of this embodiment is preferably a perforated plate 74 disposed at a position higher than the bottom of the receiving groove 71 but lower than the yarn spreading guide 73. The plate 74 is provided with a plurality of the air inlet holes 75, and the size of the air inlet holes 75 is smaller than the thermoplastic rubber powder H, so that the thermoplastic rubber powder H can be carried above the porous plate 74. The bottom of the slot 71 is provided with a ventilation channel 77. After an airflow A passes through the ventilation channel 77, the thermoplastic rubber powder H is driven through the air inlet hole 75 to form a rolling effect such that the yarn passing by The bundle 10 can evenly adhere the thermoplastic rubber powder H.

The yarn spreading cloth module 70 mainly provides the functions of yarn spreading and cloth spreading. There are two main mechanisms for yarn spreading. One is to use the yarn bundle 10 to pass through the yarn spreading guide 73 and the yarn spreading guide 73. The frictional force and tension generated between the two sides are used to spread the yarn. The second is to use the airflow A provided by the air inlet hole 75 to disperse the thermoplastic rubber powder H in the accommodating groove 71 and pass through the airflow A and the thermoplastic The rubber powder H impacts the yarn bundle 10 to spread the yarn bundle 10, and the friction force and tension with the yarn spreading guide 73 make the yarn bundle 10 expand more. Further, the present invention can also achieve the effect of increasing or decreasing the tension of the yarn bundle 10 through the position, angle, diameter and number of the guide rods 73 provided in the accommodating groove 71, and help to adjust the yarn bundle 10 Yarn spread of the yarn bundle 10.

The mechanism of the cloth distribution of the yarn spreading module 70 lies in that the yarn bundle 10 generates a surface electrostatic charge due to the friction between the yarn bundle 10 and the yarn spreading guide 73, and the static charge can cause the thermoplastic rubber The powder H can be adsorbed on the surface of the yarn bundle 10 to complete the cloth distribution process.

The yarn spreading module 70 of the present invention has the advantage that the yarn bundle 10 can be unrolled at the same time and the thermoplastic rubber powder H can be dispersed in advance between the fibers of the yarn bundle 10, which improves the subsequent thermoforming. Impregnated, achieve or approach the effect of the existing thermosetting resin process; and the thermoplastic rubber powder H can be distributed uniformly in the yarn bundle 10, and the uneven film thickness and resin can be overcome only in the subsequent hot-press molding into extremely thin sheets. Unfavorable conditions such as uneven distribution, dry yarn (no resin), discontinuous arrangement of resin or yarn bundles, and breakage.

Next, the yarn bundle 10 enters the hot-pressing module 100 after the yarn distribution module 70 is developed. It preferably includes a rolling mechanism that can heat the yarn bundle 10 in the radial direction. Pressure is applied and hot-pressed to form an ultra-thin thermoplastic fiber reinforced composite material S. The hot-pressed module 100 used in this embodiment is a double-strip hot-press or a heated roller.

Please refer to FIG. 3, the present invention may be provided with the whole-bundle arranging device X before and / or after the yarn spreading module 70. The first embodiment of the whole-bundle arranging device X is a multi-groove whole-bundle mechanism. It includes an upper roller 91 and a lower roller 93. The surfaces of the upper roller 91 and the lower roller 93 are provided with a plurality of convex portions 94 and concave portions 95 corresponding to convex and concave portions. The convex portions 94 and the concave portions 95 limit the yarn bundle 10. Position, reducing the problem that the yarn bundle 10 is turned over or folded, and the average width of the yarn spread of the yarn bundle 10 and the distance between the yarn bundles are evened.

Through the plurality of convex portions 94 and concave portions 95 of the whole bundle arranging device X, the yarn bundle 10 can be arranged neatly, and its resin content (Resin content, RC) can be adjusted according to the ultra-thin thermoplastic fiber reinforced composite material S to be formed. %), Fiber area weight (Fiber Areal Weight, FAW (g / m ² )) and width, etc., and control the spacing and arrangement uniformity of fiber yarns.

The aforementioned method of adjusting the resin content (Resin content, RC ratio, RC%) and the fiber weight per unit area (Fiber Areal Weight, FAW (g / m2)), for example, can pass through the thermoplastic rubber powder on the yarn bundle 10 The H distribution control and the compression gap control of the hot-pressing module 100 (which can squeeze out the excess resin and control the thickness) can control the ratio of the thermoplastic rubber powder H to the yarn bundle 10 and the thickness of the sheet. Effect; or when the pressing distance is fixed at the rear of the hot pressing module 100 (that is, the thickness of the ultra-thin thermoplastic fiber reinforced composite material S is fixed), each convex portion 94 of the upper roller 91 and the lower roller 93 is fixed. Increasing the number of the yarn bundles 10 in both the recesses 95 can increase the content of the S-fiber yarn of the ultra-thin thermoplastic fiber reinforced composite material that is subsequently formed, and the RC ratio will be significantly reduced; otherwise, each convex 94 and recess 95 In this yarn bundle 10, the RC ratio and the effect of controlling the fiber weight per unit area (FAW) can be increased.

The above-mentioned multi-groove whole-bundle mechanism of the whole-bundle aligning device X is an upper and lower double-roller type embodiment, which has the advantage of directly limiting the upper-roller 91 and the lower-roller 93 to pinch the limiting effect formed by the abutment. The yarn bundle 10 from the second heating unit 80 is still maintained at the original horizontal plane for processing operations, to prevent the equipment from generating additional tension on the yarn bundle 10, and reducing the problem that the continuous process tension accumulation causes the yarn bundle 10 to break. .

In addition to the double-roller type, the second embodiment may also be a single-roller type. The so-called single-roller type is substantially the same as the double-roller type, but only the upper roller 91 or the lower roller 93 is used The yarn bundle 10 is arranged in a limited position, but at this time, in order to avoid that the yarn bundle 10 cannot be kept in the recess 95, it is preferable that at least the recess 95 of a single roller is positioned higher or lower than the front end. The original horizontal position of the yarn bundle 10 comes so that the yarn bundle 10 can be angled to the original horizontal position to achieve the purpose of being located in the recess 95 and being bundled. In addition, the distance between the yarn bundles 10 can be adjusted by replacing roller sets having different width dimensions of the convex portion 94.

The third embodiment of the whole bundle arranging device X includes an adjustable needle comb set 50 and a flat roller set. As shown in FIG. 4, the adjustable needle comb set 50 includes a plurality of perpendicular to the horizontal direction of the yarn bundle 10 travel. The needle comb 51 is preferably arranged at intervals in a zigzag (or W-shaped) form, and the separation distance of the needle comb 51 can be adjusted so that the interval of the yarn bundle 10 can be increased or decreased according to demand. Avoid arranging the plurality of yarn bundles 10 too close to each other and squeezing and overlapping each other to affect the yarn spreading effect. The flattening roller group preferably includes two rollers corresponding to each other and having a flat surface, and receives the yarn bundle 10 from the adjustable needle comb group 50, because the yarn bundle 10 passes through the adjustable needle comb group 50 The fiber may be overturned and folded due to contact friction. Therefore, the yarn bundle 10 can be flattened and trimmed by subsequent setting of the flattening roller group to achieve a flattening effect.

In addition, the whole bundle arranging device X of this embodiment is mainly arranged to arrange the yarn bundles 10 at regular intervals, and the whole bundle arranging devices are used to maintain the proper spacing of the yarn bundles 10 so as not to squeeze each other and affect the yarn spreading, or Avoid too much separation of the yarn bundle 10 to cause gaps or breaks in subsequent sheet products, and the width of the yarn spread has a positive relationship with the amount of H covering the thermoplastic rubber powder. Through the equal distance of the yarn bundle 10, uniformity is achieved The yarn spreading contributes to the impregnation degree of the yarn bundle 10. In addition to the configuration of the three different whole-bundle arranging devices described above, the whole-bundle arranging device X may also adjust the order and arrangement of arrangement according to the characteristics of each embodiment of the whole-bundle arranging device X or the yarn spreading requirements of the yarn bundle 10 The type of use, using three sets of the whole bundle arrangement device, so that each of the plurality of yarn bundles 10 can achieve the best yarn spreading effect.

Further, the present invention may also provide the yarn bundle processing module 40 in front of and / or behind the yarn spreading module 70. The first preferred embodiment is to set the yarn bundle processing module 40 in front of the yarn spreading module 70. The main purpose of the yarn bundle processing module 40 is to remove the slurry and water vapor on the surface of the yarn bundle 10 so as to be used in the subsequent cloth manufacturing process. Since the surface of commercially available carbon fibers generally contains slurry, if the yarn spreading is performed directly, the yarn bundle 10 is easy to stick, which makes it difficult for the yarn bundle 10 to spread, and then affects the uniformity and thickness of the fiber yarn after the yarn expansion. This implementation For example, setting the yarn bundle processing module 40 in front of the yarn spreading cloth module 70 can remove the sizing agent and water vapor on the surface of the yarn bundle 10 first, so as to avoid affecting the yarn spreading effect due to the surface sizing agent relationship. The yarn bundle processing module 40 may be, but is not limited to, hot air, an electric heating plate, an electric heating tube, or an infrared lamp (IR lamp).

The second preferred embodiment of the yarn bundle processing module 40 is disposed behind the yarn spreading module 70. The main purpose is to avoid the thermoplastic rubber powder H attached to the surface of the yarn bundle 10 in subsequent processes. It is heated by the yarn bundle processing module 40. The heating temperature is preferably higher than the melting temperature of the thermoplastic rubber powder H in a short time, so that the thermoplastic rubber powder H can be temporarily attached. On the surface of the yarn bundle 10, the thermoplastic rubber powder H can also be pre-melted between the fibers of the yarn bundle 10, and the over-expanded yarn bundle can be reduced to the required width by heating at this time. .

In addition, before the yarn bundle 10 enters the yarn spreading module 70, the yarn bundle 10 may be arranged at intervals by a porous whole bundle group 30, as shown in FIG. 5, the porous whole bundle group 30 It includes a plate 31 and a plurality of yarn guide openings 32 spaced thereon. By passing a plurality of the yarn bundles 10 out of the yarn guide openings 32, the yarn bundle tension control module 20 will be different from each other. The yarn bundles 10 in a directional or horizontal position are gathered and regularly arranged and advance in the same direction, so as to facilitate the implementation of the subsequent yarn exhibition process. The peripheral wall of the yarn guide opening 32 is preferably made of a wear-resistant but smooth surface material, such as porcelain eyes, Teflon material, etc., which can withstand friction of the yarn bundle 10 and also prevent the yarn bundle 10 from breaking.

The first way for the yarn guide openings 32 to be spaced apart is to have two yarn guide openings 32 as a group, and multiple groups are arranged closely and regularly in a top-left, bottom-right, or bottom-right, and top-left manner. Yarn openings 32 are equidistant and arranged on the same horizontal plane, all of which can achieve the aforementioned purpose of gathering the yarn bundles 10 and regularly arranging them and advancing in the same direction. The present invention is not limited here.

Finally, a winding device 110 is disposed behind the hot-pressing module 100 to wind the ultra-thin thermoplastic fiber reinforced composite material S for subsequent transportation or processing.

The present invention corresponds to the aforementioned molding equipment for the extremely thin thermoplastic fiber-reinforced composite material S, and a method for spreading yarn and cloth thereof is provided below.

Please refer to FIG. 1 and FIG. 6, which are preferred embodiments of the yarn spreading method of the present invention. The steps include: Step S1: Provide a force to a plurality of yarn bundles, and arrange the plurality of yarn bundles at intervals and in the same direction. Go forward; Step S2: Unfold the plurality of yarn bundles by means of friction control, tension adjustment, and airflow impact, so that the plurality of yarn bundles are expanded into a plurality of fiber yarns in the horizontal direction, and the airflow disperses a thermoplastic compound The powder is distributed on the surface of the plurality of yarn bundles, and the frictional force generates electrostatic charges on the surface of the plurality of yarn bundles to adsorb the thermoplastic rubber powder; and step S3: heating and pressing the plurality of yarn bundles into one pole Thin thermoplastic fiber reinforced composite.

It can be known from the foregoing description that the present invention achieves the effect of spreading the yarns of the plurality of yarn bundles 10 evenly by means of tension, friction and maintaining the distance between the yarn bundles 10 in the manufacturing process, and successfully uses the airflow and electrostatic charge adsorption methods The thermoplastic rubber powder H is evenly adhered to the surface of the yarn bundle 10 to facilitate the quality of the subsequent forming plate.

The above are only examples of the preferred embodiments of the present invention, and are not intended to limit the scope of the rights claimed by the present invention.
