FIG. 4 is a cross-sectional view of a basalt fiber tape laminate according to an embodiment of the present invention. A second embodiment for explaining a method for producing a basalt fiber tape laminate according to a method for producing a fiber composite material.

Referring to FIGS. 1 to 4, basalt fibers are prepared (S110). The basalt fibers may extend in a first direction. The first direction may be the longitudinal direction of the basalt fibers. According to one embodiment, the basalt fiber can be produced by melt spinning a basalt ore to produce a basalt filament, and adjusting the tex or denier of the basalt filament to suit the application.

The basalt fibers can be spread (S120). The basalt fibers can be spread by shaking the basalt fibers in a second direction. The second direction may be a direction intersecting with the first direction. According to one embodiment, the basalt fibers are moved through the rollers, vibrating the bases in a direction perpendicular to the direction of movement of the basalt fibers (the longitudinal direction of the basalt fibers) have. Hot air can be applied to the basalt fibers while the basalt fibers are spread. Thus, the basalt fibers can be easily spread at uniform intervals.

The step of spreading the basalt fibers may include spreading the basalt fibers at a first temperature and spreading the basalt fibers at a second temperature lower than the first temperature. Thus, the basalt fibers can be spread more uniformly.

If, in contrast to the above-described embodiment, a surfactant is provided immediately after the basalt fibers are spread at high temperatures, as described below, it is not easy for the basalt fibers to be coated by the surfactant. However, as described above, according to an embodiment of the present invention, when the basalt fibers are spread at the first temperature and the basalt fibers are spread at the second temperature lower than the first temperature, An activator can be easily coated on the basalt fiber.

Impurities may be present on the surface of the basalt fibers. For example, the impurities may be a silane compound. Before the basalt fibers are spread, the basalt fibers may be heat treated to remove impurities remaining on the surface of the basalt fibers. Thus, the basalt fibers can be easily spread.

Surfactant may be provided to the spread basalt fibers (S130). Thus, the spacing between the basalt fibers can be more uniform. The surface of the basalt fibers may have an alkaline character. Thus, according to one embodiment, the surfactant may be a cationic surfactant, whereby the spacing of the basalt fibers provided with the surfactant may be more uniform. For example, the surfactant may include at least one of quaternary ammoniums, amine salts, and pyridium salts.

The surfactant may be provided to the basalt fibers spread as described above or alternatively may be provided to the basalt fibers in the process of spreading the basalt fibers. Specifically, according to one embodiment, after the basalt fibers are first spread, the surfactant is coated and dried on the basalt fibers, and after the basalt fibers are secondarily spread and dried, A binder may be provided to the basalt fibers as described above.

A binder may be provided to the basalt fibers provided with the surfactant (S140). The binder may comprise a hydrolyzable functional group, and an organic functional group to which it is attached. The hydrolyzable functional groups can be combined with the surfaces of the basalt fibers. More specifically, OH ^- present on the surface of the basalt fibers reacts with the hydrolyzable functional group such that the binder can be strongly bound to the basalt fibers. Further, the organic functional group may be combined with a thermoplastic resin described below. For example, the hydrolyzable functional group may include at least one of methoxy and ethoxy, and the organic functional group may include at least one of vinyl, epoxy, amino, and methacryl.

According to one embodiment, the basalt fibers provided with the surfactant may be dried before the binder is provided to the basalt fibers provided with the surfactant. For example, the basalt fiber provided with the surfactant may be dried using hot air.

The thermoplastic resin may be impregnated into the basalt fibers by providing a thermoplastic resin to the basalt fibers provided with the binder (S150). For example, the thermoplastic resin may include at least one of polyethylene, polypropylene, polycarbonate, nylon, polyurethane, and polyamide.

As noted above, the basalt fibers may be provided with the binder, which may include the hydrolyzable functional group associated with the surface of the basalt fibers, and the organofunctional group associated with the thermoplastic resin have. As a result, the bonding force between the basalt fibers and the thermoplastic resin can be improved, thereby minimizing the phenomenon that the basalt fiber is extracted from the thermoplastic resin.

The basalt fiber 100 impregnated with the thermoplastic resin may be passed through a slit to produce a basalt fiber tape 100 (S160), as shown in FIG. In the basalt fiber tape 100, the basalt fibers 110 extending in the first direction (x direction in FIG. 2) may be surrounded by the thermoplastic resin 120. In the basalt fiber tape 100, the basalt fibers 110 may be spaced apart from each other in the second direction (y direction in FIG. 2).

1, the basalt fiber tape having passed through the slit may be heated and passed through a roller (S170). Accordingly, the thermoplastic resin in the basalt fiber tape passed through the slit may not be hardened immediately. As a result, at least part of the thermoplastic resin in the basalt fiber tape may be discharged to the outside during the passage of the basalt fiber tape through the roller. Accordingly, the proportion of the thermoplastic resin in the basalt fiber tape decreases and the proportion of the basalt fiber increases, so that the strength of the basalt fiber tape can be increased.

According to the above-described method, a plurality of the above-mentioned basalt fiber tapes can be produced. A plurality of the basalt fiber tapes may be laminated to produce a basalt fiber tape laminate.

Specifically, as shown in Fig. 3, the basalt fiber tape laminate can be manufactured by laminating a plurality of the basalt fiber tapes and thermocompression bonding. In the process of thermocompression of a plurality of laminated basalt fiber tapes, the thermoplastic resin in the basalt fiber tape may melt to produce the basalt fiber tape laminate from a plurality of the basalt fiber tapes.

Alternatively, as shown in FIG. 4, a plurality of the basalt fiber tapes may be laminated, and a resin film 130 may be provided between the plurality of basalt fiber tapes. In this case, the thermoplastic resin and the resin film 130 in the basalt fiber tape melt in the process of thermocompression of the plurality of laminated basalt fiber tapes and the resin film 130, The above-mentioned basalt fiber tape laminate can be produced.

The tensile strength of the basalt fiber tape laminate can be controlled according to the temperature and the pressure at which the plurality of basalt fiber tapes are thermocompression bonded.

Specifically, when the pressure for thermally bonding a plurality of the basalt fiber tapes is relatively low, the tensile strength of the basalt fiber tape laminate may increase as the thermocompression bonding temperature increases. In addition, when the pressure for thermally bonding a plurality of the basalt fiber tapes is relatively high, the tensile strength of the basalt fiber tape laminate may decrease as the thermocompression bonding temperature increases.

Further, when the temperature at which the plurality of basalt fiber tapes are thermocompression-bonded is relatively low, the tensile strength of the basalt fiber tape laminate may increase as the thermocompression pressure increases. In addition, when the temperature for thermocompression bonding of the plurality of basalt fiber tapes is relatively high, the tensile strength of the basalt fiber tape laminate may decrease as the thermocompression pressure increases.

In addition, according to one embodiment, the types of the thermoplastic resin included in the plurality of basalt fiber tapes constituting the basalt fiber tape laminate may be different from each other. For example, the basalt fiber tape laminate may comprise a basalt fiber tape comprising polyurethane, and a basalt fiber tape comprising polypropylene. Accordingly, depending on whether the thermoplastic resin is mixed or blended, a basalt fiber composite material having various properties depending on applications and a method of manufacturing the same can be provided.

According to an embodiment, when the resin film 130 is provided between a plurality of the basalt fiber tapes as described above, the resin film 130 may be formed of the thermoplastic resin included in the basalt fiber tape It may be a different kind of resin. Accordingly, a basalt fiber composite material having various properties and a manufacturing method thereof can be provided.

Hereinafter, the evaluation results of the characteristics of the basalt fiber composite according to the embodiment of the present invention will be described.

12K carbon fiber, 2400 Tex basalt fiber, and thermoplastic resin.

The carbon fiber and the basalt fiber were prepared by spreading tow through a tow spreading apparatus and a spread tow having a fiber width of about 7 mm to 20 mm was prepared through a furnace friction roller to improve spreadability.

After the spreading process, in order to impregnate the carbon fiber and the basalt fiber into the polypropylene, the impregnation tank was filled with polypropylene and heated to dissolve the polypropylene. The molten polypropylene was impregnated with the carbon fiber and the basalt fiber, and a carbon fiber tape (resin content 66 wt%) having a width of 18 to 19 mm and a thickness of 0.15 mm, a basalt fiber tape having a width of 16 to 19 mm and a thickness of 0.25 mm 38.1 wt%).

The number of the carbon fiber tapes to be laminated, the process temperature , And pressure were adjusted as shown in [Table 1] below.

As can be seen from Figs. 6 to 10, it can be confirmed that the surface characteristics of the carbon fiber tape laminate to be manufactured are changed according to the applied pressure and temperature after the carbon fiber tape is laminated. In other words, it can be seen that the surface characteristics of the carbon fiber tape laminate or the basalt fiber tape laminate can be controlled by controlling the pressure and the temperature.

As shown in Figs. 11 and 2, the carbon fiber tape and the basalt fiber tape were thermally bonded to each other as in the case of Example 1-1, Example 1-3, Example 3-1, and Example 3-3 It can be seen that the tensile strength of the basalt fiber tape laminate increases as the thermocompression temperature increases from 130 캜 to 140 캜 when the pressure is relatively low (5 MPa). This is presumably because the viscosity of the thermoplastic resin is lowered as the temperature is increased and the lamination has progressed more effectively than the relatively lower temperature.

Further, as in the case of Examples 2-1, 2-3, 4-1, and 4-3, when the pressure for thermocompression bonding of the plurality of basalt fiber tapes is relatively high (10 MPa) As the compression temperature is increased from 130 ° C to 140 ° C, the tensile strength of the basalt fiber tape laminate decreases. This is presumably because the spacing of the fibers increased as the pressure increased, resulting in a decrease in the mechanical strength of the basalt fiber tape laminate.

Further, as in the case of Examples 1-1, 2-1, 3-1, and 4-1, when the temperature at which a plurality of the basalt fiber tapes are thermocompression bonded is relatively low (130 ° C) As the thermocompression pressure increases from 5 MPa to 10 MPa, the tensile strength of the basalt fiber tape laminate increases. This is presumably because lamination was effectively carried out by using a thermoplastic resin having a relatively low temperature by high pressure.

Further, as in the case of Examples 1-3, 2-3, 3-3, and 4-3, when a plurality of the basalt fiber tapes are thermocompression-bonded at a relatively high temperature (140 ° C) As the thermal compression pressure increases from 5 MPa to 10 MPa, the tensile strength of the basalt fiber tape laminate decreases. This is presumably because a high pressure was applied to the thermoplastic resin having a low viscosity at a relatively high temperature to increase the spacing of the fibers and to decrease the mechanical strength of the basalt fiber tape laminate.

In other words, the tensile strength can be controlled by adjusting the temperature and pressure in the thermocompression bonding step of laminating the carbon fiber tape and the basalt fiber tape to produce the carbon fiber tape laminate and the basalt fiber tape laminate can confirm.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention is not limited to the disclosed exemplary embodiments. It will also be appreciated that many modifications and variations will be apparent to those skilled in the art without departing from the scope of the present invention.
