The connection way of FRP structures

1. Lap connection

Lap connection is one of the most widely used fiberglass connection methods at present. It is mainly suitable for plate connection, pipe connection and other fields. Specifically, the junction of two fiberglass components is connected in an overlapping manner, and then reinforced with glue or bolts. Lap connection has a larger connection area, can withstand greater force, and is also more economical and practical.

2. Adhesive connection

Adhesive connection refers to the connection method that uses special glue to fit fiberglass parts together. This connection method requires the selection of appropriate glue materials. According to the characteristics of FRP materials, glue with bonding strength and corrosion resistance should be selected. The advantage of adhesive connection is that the connection is firm, beautiful and does not affect the appearance. However, its strength and weather resistance will be affected by weather, temperature and other factors.

3. Mechanical connection

Mechanical connection is a way to firmly connect fiberglass parts using bolts, nuts, corner codes and other parts. The advantage of this connection method is that it has a solid structure, good stability, and is detachable for easy maintenance and replacement. However, its disadvantage is that it requires specialized parts and the cost is relatively high.

The above is an introduction to the main types and usage of fiberglass connection methods. In actual production, the choice of connection method needs to be determined based on the specific conditions and usage requirements of the FRP components. Generally speaking, various connection methods have their advantages and disadvantages in different fields and applications. We need to choose the appropriate connection method according to the specific situation.
