摘要
A reinforced pipe and a method of preparing the reinforced pipe are provided. The reinforced pipe has repair area where a wrinkle bend is present in a center section of the repair area. The reinforced pipe comprises a unidirectional fabric circumferentially wrapped around the repair area of the pipe so as to result in multiple layers of the unidirectional fabric around the repair area. The unidirectional fabric is composed of high-performance fibers with at least 90% of the high-performance fibers oriented in the 90° direction, and the unidirectional fabric is wrapped such that the high-performance fibers run in the axial direction. The reinforced pipe further comprises a bidirectional fabric wrapped of over the unidirectional fabric such the at least one layer of bidirectional fabric is wrapped over the unidirectional fabric.
