Description

Glass fiber aramid blended fabric

technical field

The utility model relates to the field of composite fabrics, in particular to an aramid fiber and glass fiber mixed fabric used in ships and protective materials, in particular to a glass fiber and aramid mixed fabric.

Background technique

Glass fiber is made of glass balls or waste glass through high-temperature melting, drawing, winding, weaving and other processes. It is a very good metal substitute material. It is used in construction, ships, chemical pipelines, automobiles, aviation, wind Power generation and other fields have broad application prospects, and its application fields are still expanding, and the global market space is huge. The traditional glass fiber is a single FRP product, which is only rigid but not flexible, not impact resistant, and not tough enough. Although FRP is strong, its material is relatively brittle.

Contents of the invention

In view of the above problems, the purpose of this utility model is to provide a glass fiber and aramid fiber blended fabric, which changes the shortcomings of the previous single glass fiber products, which are only rigid, relatively brittle, and easy to damage, and can obtain a low-cost and high-toughness composite structure.

Realize the technical scheme of the utility model as follows:

Glass fiber and aramid blended fabrics, including warp fiber bundles, weft fiber bundles, chopped strands, warp fiber bundles and weft fiber bundles are evenly arranged, and evenly arranged warp fiber bundles and evenly arranged weft fibers The bundles are interlaced and stacked, chopped strands are uniformly scattered between the warp fiber bundles and the weft fiber bundles, the warp fiber bundles are large tow aramid fibers, and the weft fiber bundles are large tow glass fibers.

Further, the warp fiber bundles and weft fiber bundles are interlaced in a cross shape.

Further, the density ratio of the aramid fibers, glass fibers and chopped strands is 5:7:2.

The above-mentioned scheme is adopted, instead of only using a single glass fiber weaving forming fabric in the past, glass fiber and aramid fiber are used as warp fiber bundles and weft fiber bundles, and the warp fiber bundles and weft fiber bundles are crossed. The patterns are interlaced and laid in layers, and a layer of chopped yarn is scattered between the warp and weft fiber bundles, thereby weaving to form a low-cost and high-toughness composite structure, which makes the fabric both rigid and flexible, and impact-resistant; Chopped yarn scattered between the warp and weft fiber bundles greatly increases the soak-out speed of the finished part during infusion.

Description of drawings

Fig. 1 is a structural representation of the utility model;

In the figure, 1 is a warp fiber bundle, 2 is a weft fiber bundle, and 3 is a chopped yarn.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

In Fig. 1, since the warp fiber bundle and the weft fiber bundle are laid in layers, the weft fiber bundle is represented by a solid line, and the warp fiber bundle is represented by a dotted line, and the weft fiber bundle is laid on the warp fiber bundle, while Chopped strands are evenly scattered between the warp and weft fiber bundles, and the chopped strands are represented by crossed dotted lines. The positional relationship between the vertical fiber bundles and the weft fiber bundles is not limited to the laying method described in FIG. 1 , and the weft fiber bundles can also be laid under the warp fiber bundles.

As shown in Figure 1, glass fiber and aramid fiber blended fabrics include warp fiber bundles 1, weft fiber bundles 2, and chopped strands 3. The warp fiber bundles and weft fiber bundles are evenly arranged, and the evenly arranged warp fiber bundles The evenly arranged weft fiber bundles are interlaced and laid in a cross shape, and a layer of chopped strands is evenly scattered between the warp fiber bundles and the weft fiber bundles. bundles and chopped strands are woven to form a fabric, the warp direction fiber bundles are large tow aramid fibers, and the weft direction fiber bundles are large tow glass fibers, and the density ratio of the aramid fibers, glass fibers, and chopped strands is 5:7:2. Or the warp direction fiber bundle is a large tow glass fiber, and the weft direction fiber bundle is a large tow aramid fiber.

The utility model changes the previous use of only a single glass fiber weaving forming fabric, and instead uses glass fiber and aramid fiber as warp fiber bundles and weft fiber bundles. The density of aramid fiber, glass fiber and chopped yarn is proportional. Warp-knitting fiber bundles, weft fiber bundles and chopped strands are woven to form a low-cost and high-toughness composite structure. Aramid fiber has good toughness, and its good toughness well compensates for the glass fiber. Insufficient, the fabric formed by weaving has both rigidity and flexibility, which has the toughness of steel plate and the flexibility of bulletproof vests, and is impact resistant. In addition, the strength is also greatly increased, the weight is also greatly reduced, and the fireproof, heat insulation and puncture resistance performance is also slightly improved. , and a layer of chopped strands scattered between the warp and weft fiber bundles can also effectively increase the soaking speed of the finished product during infusion, and the improvement effect is more obvious, effectively shortening the process flow and improving efficiency. Reduced production costs. See Table 1. Table 1 is a comparison table of the penetration rate of glass fiber and aramid blended fabrics with chopped yarn and without chopped yarn. The penetration test is carried out on samples with different layers. It can be seen from Table 1 that the same number of layers The soaking time of the sample and the sample after adding chopped yarn is shorter than that without chopped yarn, and it is more obvious. It can be seen that after adding chopped yarn, the infusion speed of the woven product has been significantly improved. improvement.
