Nori culture props and their manufacturing methods

摘要

PROBLEM TO BE SOLVED: To provide a support for nori cultivation made of FRP, which is excellent in handleability by hand, can achieve both light weight and high rigidity, is relatively inexpensive and is highly practical. SOLUTION: This is a support for cultivating seaweed having a composite structure having a core layer made of a thermoplastic resin, an FRP layer formed on the outer periphery thereof, and a coating layer formed on the outer periphery of the FRP layer. The core layer is composed of a thermosetting resin which is a matrix component constituting the FRP layer and a thermoplastic resin having a chemical affinity, and the FRP layer is formed of glass fibers on the outer periphery of the core layer in the longitudinal direction. And long fiber reinforced fibers including carbon fibers are bonded in a vertical line shape, the carbon fibers are arranged on the outer peripheral side of the FRP layer, and the cross-sectional area ratio of the glass fiber to the carbon fiber in the cross section of the FRP layer is 60: The ratio is 40 to 95: 5, and the coating layer is a support for cultivating seaweed, which is composed of a thermoplastic resin having a chemical affinity with the thermosetting resin which is the matrix component.
