Frp anchor bolts can be used forvarious applications, such as:

Types of Frp Anchor Bolts
 

There are two main types of frp anchor bolts: field-laminated and pre-fabricated.

Field-Laminated Frp Anchor Bolts
 

Field-laminated frp anchor bolts are made by wrapping FRP fabric around a steel core and curing it with resin on site. They can be customized to fit any shape or size of the hole and can carry load into the concrete to improve bond strength, or through the concrete to transfer load for increased capacity. They are available in carbon and E-glass fibers, with diameters ranging from 1/4" (6.4 mm) to 1 1/2" (38.1 mm) in custom lengths.

Pre-Fabricated Frp Anchor Bolts
 

Pre-fabricated frp anchor bolts are made by molding FRP material around a steel core in a factory. They have a standard hex head and a flange that distributes pressure where the bolt meets the surface, eliminating the need for a separate washer. They are chemical and oil resistant, nonconductive, and lightweight. They have diameters ranging from 1/4" (6.4 mm) to 3/4" (19.1 mm) and lengths ranging from 1/2" (12.7 mm) to 5" (127 mm).

Performance and Parameters of Frp Anchor Bolts
 

The performance and parameters of frp anchor bolts depend on the type, material, diameter, length, spacing, and installation method of the bolts. Some general guidelines are:
