Kind Code:
A1
Abstract:
This method for manufacturing a composite strand includes a first step, a second step, and a third step. The first step is for forming a core intermediate by impregnating a high-strength fiber bundle with an uncured resin matrix. The second step is carried out after the first step. Additionally, the second step is for intertwining a plurality of steel outer-periphery wire members around the outer periphery of the core intermediate.
