Abstract

The utility model discloses a high-impact-resistance glass fiber cloth, which comprises a foam rubber layer, wherein glass fibers are respectively arranged in the foam rubber layer along the warp direction and the weft direction, and the glass fibers arranged in the warp direction and the weft direction are both slightly longer than the length of the foam rubber layer in the direction of the warp direction and the weft direction, so that the glass fibers are in a natural micro-rolling state in the foam rubber layer; and the upper surface and the lower surface of the foamed rubber layer are both provided with a polytetrafluoroethylene layer. Through above-mentioned structure, shock resistance when can very big promotion glass fiber as the filler is worth wideling popularize.

Description

High-impact-resistance glass fiber cloth

Technical Field

The utility model relates to a glass fiber technical field, especially a high impact resistance glass fiber cloth.

Background

The glass fiber is an inorganic non-metallic material with excellent performance, has various varieties, has the advantages of good insulativity, strong heat resistance, good corrosion resistance and high mechanical strength, but has the defects of brittleness and poor wear resistance. The base fabric made of glass fiber is usually not the choice for the tensile strength of the reinforcing material in the composite material, however, when the glass fiber is added into the composite material, the rigidity of the composite material is increased and the toughness is reduced, so that the material is not resistant to impact.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a high impact resistance glass fiber cloth, the shortcoming that rigidity and toughness can not compromise when can effectually overcoming glass fiber cloth as combined material base cloth.

In order to achieve the above purpose, the technical scheme of the utility model is that:

the high-impact-resistance glass fiber cloth comprises a foamed rubber layer, wherein glass fibers are arranged in the foamed rubber layer along the warp direction and the weft direction respectively, and the glass fibers arranged in the warp direction and the weft direction are slightly longer than the foamed rubber layer in the warp direction and the weft direction so that the glass fibers are in a natural micro-rolling state in the foamed rubber layer; and the upper surface and the lower surface of the foamed rubber layer are both provided with a polytetrafluoroethylene layer.

Furthermore, the glass fiber arranged in the warp direction and the glass fiber arranged in the weft direction are both 1.05-1.07 times of the length of the foaming rubber layer in the direction of the glass fiber and the glass fiber.

Further, the single strand fineness of the glass fiber is 30D-70D.

Further, the distance between adjacent yarns of the glass fibers arranged in the warp direction is 0.1-0.15 times of the weft width of the foamed rubber layer; and the space between adjacent glass fiber yarns arranged in the weft direction is 0.15-0.2 times of the weft width of the foamed rubber layer.

Has the advantages that: make its production natural microcoil with glass fiber setting in the foaming rubber layer, thereby make the utility model discloses when receiving stronger impact, glass fiber can have certain extension space at foaming rubber layer tensile deformation in-process, prevents that the condition of brittle fracture from taking place, and then has reached the effect that promotes shock resistance.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The high impact resistance glass fiber cloth as shown in fig. 1 and fig. 2 comprises a foam rubber layer 1 as an intermediate layer, wherein a plurality of glass fibers 2 are respectively arranged in the foam rubber layer along the warp direction and the weft direction. The glass fiber arranged along the longitudinal direction of the foam rubber layer is slightly longer than the longitudinal length of the foam rubber layer, and the glass fiber arranged in the latitudinal direction of the foam rubber layer 1 is slightly longer than the latitudinal length of the foam rubber layer. When the glass fiber foam material is manufactured, two ends of the glass fiber are fixed and then immersed into rubber which is foaming, and after the rubber foaming is finished, the glass fiber is naturally in a natural and disordered micro-roll state under the driving of bubbles, wherein the state is similar to a spider silk structure and has strong impact resistance. Meanwhile, in order to delay the aging of the foamed rubber layer 1, a polytetrafluoroethylene layer 3 is arranged on the upper surface and the lower surface of the foamed rubber layer.

As a further improvement of the embodiment, the glass fibers arranged in the warp direction and the glass fibers arranged in the weft direction are 1.05-1.07 times of the length of the foaming rubber layer in the direction of the glass fibers.

In a further improvement of the above embodiment, the single strand fineness of the glass fiber is 30 to 70D.

As a further improvement of the above embodiment, the spacing between adjacent yarns of the glass fibers arranged in the warp direction is 0.1 to 0.15 times of the weft width of the foamed rubber layer; and the space between adjacent glass fiber yarns arranged in the weft direction is 0.15-0.2 times of the weft width of the foamed rubber layer.
