強基材の提供を目的とする。As a molding method when the molded body has a three-dimensional structure having a certain size, a hand in which a resin is applied and impregnated while cutting and reinforcing a reinforcing base material such as a woven fabric or a chopped strand mat. A matched metal die that preforms a reinforcing base material by a lay-up method or a preform method in a shape close to the shape of the molded body, inserts this preform into the mold, and supplies resin to the mold to cure to obtain a molded body Method and RIM method. Further, there is also a filament winding method in which glass fibers impregnated with resin, which have a special shape, are wound around a mandrel and cured and molded. However, these molding techniques also require equipment for manufacturing preforms in the case of the preform method, and require considerable skill to reduce variations in the obtained preforms. Also in the case of the FW method, equipment for winding glass fibers is required, and the shape of the obtained molded product is also considerably restricted. The hand layup method naturally has a problem that productivity is poor. An object of the present invention is to provide a reinforcing base material suitable for forming a molded product having a three-dimensional structure in view of the above situation.

点で望ましい。Means for Solving the Problems The inventors of the present invention have made extensive studies to solve the above-mentioned problems, and as a result, in a glass fiber knitted fabric, a glass whose constituent yarns are aligned yarns of glass fiber yarns and glass fiber bulky yarns. It was found that the problem can be solved by using a fiber knitted fabric, and further, the tex count of the above-mentioned aligned yarn is in the range of 200 to 500, and the glass fiber bulky yarn in the aligned yarn is It has been found that the problem can be solved by using a glass fiber knitted fabric having a tex count ratio of 25 to 75% and a knitted mass of 400 to 1100 g / m 2 . The knitting structure is roughly divided into weft knitting and warp knitting. The weft knitting is further divided into flat knitting, rubber knitting, double-sided knitting, pearl knitting, and the like, and warp knitting is divided into half knitting, reverse half knitting, quinz cord knitting, double atlas knitting, and the like. The structure of the glass fiber knitted fabric of the present invention is not particularly limited, but it is desirable that the structure does not have front and back. Since the end of the knit is easily rolled up when the structure has a front and back like a flat knit,
Workability is poor when fitting to a mold. In addition, in the knitted fabric, since the weft knitting is generally more elastic than the warp knitting,
The weft knitting of the glass fiber knitted fabric of the present invention is more preferable than the warp knitting. In the case of weft knitting as well, rubber knitting, rib knitting and the like are preferable in terms of stretchability and knitting property.

なる。In the glass fiber knitted fabric of the present invention, the aligning yarn of the ordinary glass fiber yarn and the bulky yarn obtained by subjecting the glass fiber yarn to the bulky process is used as a constituent yarn, and the tex count of the aligning yarn is in the range of 200 to 500. Are in. Since the surface of glass fiber is smooth, it is slippery and is not very suitable as a constituent material of a knitted fabric. When a knitted fabric is knitted with only glass fiber yarn, a partial misalignment is likely to occur during handling, and when a molded body is formed, this portion causes a poor appearance and causes uneven thickness. The glass fiber bulky yarn has loops and fluffs on the surface, which prevents the yarns from slipping. The bulky yarn of glass fiber includes a single effect yarn and a core effect yarn, but in the present invention, the core effect yarn is preferable.
In the case of single effect yarn, the bulkiness is limited because one yarn is bulky, but in the case of core effect yarn, the bulkiness is increased because another yarn is entangled with the core yarn. Therefore, it is possible to increase the slip resistance of the thread members. By inserting bulky yarns in the constituent yarns, the yarns become less slippery, the knit structure is stabilized, and misalignment during handling does not occur.

が大きくなるため機械強度の点で問題になる。The tex count of the draw-aligning yarn used in the present invention is preferably in the range of 200 to 500. This is because the knitted fabric of the present invention is used as a reinforcing material for FRP and therefore needs to have a certain volume effect. In the case of a thin knit, it is necessary to stack many layers to obtain the required thickness of the molded body, and the effect of using the knit is lost in terms of cost. Therefore, the number of draw thread is 200
More than tex is required. In addition, the count of the aligned yarn is 50
When it is larger than 0 tex, it takes time to impregnate the resin later, and the molding cycle becomes long. In addition, when the molded body is viewed microscopically, the ratio of the portion having no reinforcing material occupies a large amount, which causes a problem in mechanical strength.

嵩高性を有するため樹脂に対する含浸性が優れている。The glass fiber knitted fabric of the present invention using such a draw-aligned yarn has a mass of approximately 400 to 1100 g /
m 2 and is a reinforcing base material having elasticity. When the mass is less than 400 g / m 2, the thickness of the knitted fabric itself when stretched and fitted to the mold becomes thin, and it becomes difficult to obtain the required thickness of the molded body with only one layer. Also,
If the mass is more than 1100 g / m 2 , the impregnation of the resin will be poor and the handleability will be poor. In the glass fiber knitted fabric of the present invention, the aligning yarn is composed of the glass fiber yarn and the glass fiber bulky yarn as described above, and the composition ratio thereof is 25 to 75 for the glass fiber bulky yarn in terms of count ratio.
%. By using bulky yarns together, slippage between the yarns is suppressed and misalignment is less likely to occur during handling. Also, by knitting bulky yarn, the knitted fabric can have a volume effect. That is, when the mass is the same, the thickness can be increased, and therefore, it becomes possible to form the reinforcing layer having the required thickness on the molded body with one knitted fabric. Further, the bulky yarn itself is excellent in impregnation with the resin because the filament bundle constituting the yarn is in an opened state and the knitted fabric is bulky.

るようにした。The ratio of bulky yarn in the draw-aligned yarn is 25 to
When it is less than 25%, the effect of preventing misalignment of the knitted fabric is small, the volume effect on the knitted fabric is not sufficiently obtained, and the impregnation property to the resin is not good. When it is more than 75%, the knitting property is unstable,
For example, the width of the knitted fabric may change. This just its impact for large variations in the yarn properties towards bulky yarn as compared to the normal yarn due to appear in the knit. Therefore, in the present invention, the influence thereof is reduced by using the ordinary glass fiber yarn and the bulky yarn in combination.

へ戻る復元力が弱く、取扱い性が悪くなる。The glass fiber knitted fabric of the present invention can be knitted using an ordinary knitting machine, but it is preferable to use a weft knitting machine from the viewpoint of stretchability of the knitted fabric. In the case of weft knitting, the knitting conditions are 3 to 7 / inch gauge gauge and 30 stitches.
-60, and preferably 45-55. 3rd time
When it is less than 0, the structure is too deep for the yarn count used in the present invention and the elongation is insufficient. On the other hand, when it is larger than 60, the structure becomes too coarse, and when it is extended, the restoring force to return to its original state is weak and the handleability becomes poor.

Since the glass fiber yarn and the glass fiber bulky yarn are used together in the constituent yarns, the knitted fabric has a certain thickness, and the resin is well impregnated, so it is sufficient to use one layer. It is possible to form a reinforcing material layer having a thickness capable of exerting mechanical strength. Furthermore, since the glass fiber yarn and the glass fiber bulky yarn are aligned and used, a knitting property is good and a glass fiber knitted fabric having a stable knitting structure can be obtained.
