Description

Technical Field

[0001] This utility model relates to the field of carbon fiber cloth technology, and in particular to a carbon fiber prepreg cloth. Background Technology

[0002] Carbon fiber cloth is a new type of high-strength, high-modulus polymer inorganic fiber material with a carbon content of over 95%. It has a low density, approximately one-quarter that of steel, making it lightweight and easy to install, with virtually no increase in component weight or cross-sectional dimensions. Simultaneously, it possesses extremely high strength, with tensile strength far exceeding that of ordinary steel, achieving the same reinforcement effect. It is resistant to corrosion from acids, alkalis, and salts, has a long service life in harsh environments, and effectively prevents the penetration of harmful media, protecting the internal structure. It is also flexible, can be freely cut, bent, and wound into various shapes, offering significant advantages for reinforcing various curved and irregularly shaped components, and can tightly bond with reinforced concrete surfaces. It features tight bonding; superior anti-aging and anti-fatigue properties, maintaining stable performance over a long period and reducing maintenance costs; long storage time and long operable life; environmentally friendly and pollution-free, allowing construction even in residential areas; and good electrical and thermal conductivity. While carbon fiber itself has high strength, if it is poorly bonded to resin, it is prone to fiber pull-out damage under external forces. Consequently, the performance advantages of carbon fiber cannot be fully realized, failing to achieve the desired application effect. Therefore, ensuring a good bond between the two is crucial. Thus, improvements are needed to address the aforementioned issues. Utility Model Content

The fourth fiber strip 4 is located between the two third fiber strips 3, and is positioned at the lower end of the protrusion of the first fiber strip 1 and the upper end of the concave part of the second fiber strip 2; the third fiber strip 3 and the fourth fiber strip 4 facilitate the weaving of the fiber cloth; the first fiber strip 1, the second fiber strip 2, the third fiber strip 3 and the fourth fiber strip 4 are all corrugated, the protrusions and concave parts of the first fiber strip 1 and the second fiber strip 2 are misaligned, and the protrusions and concave parts of the third fiber strip 3 and the fourth fiber strip 4 are also misaligned; the corrugated shape of the first fiber strip 1, the second fiber strip 2, the third fiber strip 3 and the fourth fiber strip 4 facilitates weaving.

[0021] In this invention, the bottom surface of the protrusion of the first fiber strip 1 has multiple equidistant first soaking grooves 5, and the top surface of the recess of the first fiber strip 1 has multiple equidistant second soaking grooves 6. The top surface of the protrusion of the second fiber strip 2 has multiple equidistant third soaking grooves 7, and the bottom surface of the recess of the second fiber strip 2 has multiple equidistant fourth soaking grooves 8.

[0022] Working principle: In use of this invention, firstly, multiple first fiber strips 1 and multiple second fiber strips 2 are arranged.
