Problems solved by technology

[0003] With the continuous emergence of new technologies, new structures, and new functions in the global optical cable and cable industry, the existing types of reinforced plastic rods can no longer fully meet the requirements of technological progress.
Due to the secondary pultrusion molding of the existing composite core for cables, the molecular structure of the inner and outer layers of reinforced plastic resin is not continuous, resulting in low production efficiency and poor bending performance of the product.

Abstract

The invention relates to a reinforced plastic bar as well as a production device and a production method thereof. The reinforced plastic bar is characterized by comprising a thermal-cured resin basal body and reinforcing fiber yarns, wherein the reinforcing fiber yarns are distributed in the thermal-cured resin basal body, the reinforcing fiber yarns are divided into two types, the strength of first type fiber yarns is higher than that of the second type fiber yarns, and the second type fiber yarns are distributed on the periphery of the first type fiber yarns. The reinforced plastic bar has the advantages that the production efficiency is high, the texture is light, the tensile strength is high, the high-temperature resistance and the bending property are good, environmental friendliness and energy conservation can be realized, the cost performance is high, and the application range is wide.

Description

technical field [0001] The invention relates to a reinforced plastic rod and a preparation method thereof, belonging to the technical field of composite materials. Background technique [0002] In the 1970s, people developed and tried to use organic composite materials instead of metal materials for the tensile strength members in the optical cable structure. So far, the products mainly include glass fiber reinforced plastic rods for optical cables, aramid fiber reinforced plastic rods for optical cables, and glass fiber reinforced yarns for optical cables. Aramid fiber yarn is prepared by thermosetting pultrusion process. At the end of the 20th century and the beginning of the 21st century, Japan and the United States developed composite composite core cables. After 2000, some domestic universities, scientific research institutes and enterprises also began to pay attention to, research and develop composite material synthetic core cables. The name of the publication numbe...
