One of the most proficient techniques of the sheet winding (SW) method involves wrapping prepreg primarily in the 0-degree, 90-degree, and 45-degree directions. This combination allows for the creation of pipes with various strength characteristics. Furthermore, by effectively combining GF and CF, it is possible to achieve an even wider range of strength properties.

• plastic

In addition to CF and GF, composite materials can be easily created by combining various heterogeneous materials such as organic fibers (cotton yarn, vinylon fibers, etc.), plant-based fibers, metal fibers (boron fibers, alumina fibers), and pulp. All of these are collectively referred to as FRP. The strength of FRP is governed by the fibers (reinforcement materials), but the role of the matrix resin is to impart properties such as weather resistance, corrosion resistance, flame retardancy, heat resistance, and electrical characteristics to the FRP, based on the inherent properties of the resin.

- Especially capable of producing extremely thin-walled pipes made of single plastic. - Easy to adjust thickness through various combinations of prepregs used and the number of layers (PLY count). - Capable of manufacturing with a wall thickness of t = 0.2mm or more.

Composite refers to the combination of two or more materials of different types, qualities, or forms, meaning mixing, hybridization, or synthesis. A composite is a complex material, and the materials created through this complex process are called composite materials. The purpose of creating composite materials (COMPOSITE MATERIALS) is to achieve properties that cannot be obtained from a single material, thereby providing products that meet customer needs with excellent performance and functionality. The FRP composite pipes from Hopeck Co., Ltd. are created by combining reinforcing materials such as fibers and supporting materials with various matrices. In addition to the combination of CFRP and GFRP, it is also possible to combine various materials such as aramid + Dyneema, metals, thermoplastic plastics, and wood. 【Features】 - Adjustable thickness is possible - Easy hybridization through the combination of different materials For more details, please contact us or download the catalog.

Our company manufactures a wide range of commercial FRP fishing rods for offshore, nearshore, and coastal fisheries across the country. In particular, the "Offro" and "Tsugibane" rods for catching bonito and tuna, developed by Hopeck Co., Ltd., are our flagship fishing rods. They are made of FRP (fiberglass) and feature a long single-piece design. Mass production began in Japan for the first time in 1970, and now they are sold not only domestically but also worldwide under the product name OFRO "Offro." The Tsugibane is characterized by its two-piece design, created by the casting method of the tip and butt sections. Compared to traditional single-piece rods, it offers greater convenience, cost-effectiveness, and enhanced functionality, making it a truly professional bonito rod suitable for the 21st century. Additionally, we develop and manufacture many types of fishing rods for various target fish (shellfish, seaweed, etc.). [For more details, please download the catalog or feel free to contact us.]

Our unique pipe manufacturing technology, known as the SW (Sheet Winding) method (a molding technique that layers prepreg sheets and heats and cures them), produces composite materials with various characteristics as mentioned above. - SW-CFRP rolls are made of carbon fiber, making them lightweight, low inertia, and suitable for ultra-high-speed rotation. With a high longitudinal elastic modulus, they exhibit minimal deflection and can achieve greater rigidity than metal rolls, allowing for smaller diameter rolls and contributing to space-saving designs. - SW-GFRP rolls are made of fiberglass and are suitable for rolls that require relatively low rigidity or for insulation applications that leverage the properties of FRP. Additionally, they can be manufactured at a lower cost, allowing us to propose rolls tailored to your needs by effectively combining them with CFRP. 【Features】 [SW-CFRP Rolls] ○ Lightweight and low inertia, suitable for ultra-high-speed rotation ○ High longitudinal elastic modulus results in minimal deflection and increased rigidity compared to metal rolls ○ Enables smaller diameter rolls, contributing to space-saving designs ● For more details, please contact us or download the catalog.

Our company manufactures a wide range of commercial FRP fishing rods for offshore, coastal, and deep-sea fisheries across the country. In particular, the "Offro" and "Tsugibane" rods for catching skipjack and tuna, developed by Hopeck Co., Ltd., are our flagship fishing rods. Made from FRP (fiberglass), these long rods are characterized by being one-piece, and mass production began in Japan for the first time in 1970. Now, they are sold not only domestically but also worldwide under the product name OFRO "Offro." The Tsugibane features two joint rods created by a casting method that combines the tip and butt sections, which is its most significant characteristic. Compared to traditional one-piece rods, it offers greater convenience, cost-effectiveness, and additional functionality, making it a truly professional skipjack rod suitable for the 21st century. Additionally, we are developing and manufacturing many fishing rods designed for various target species (shellfish, seaweed, etc.). For more details, please contact us or download the catalog.

At Hopek Co., Ltd., we manufacture various types of FRP pipes, among which plastic reinforced with carbon fibers is called CFRP (Carbon Fiber Reinforced Plastics). Due to its functionality and versatility, it is widely used as a cutting-edge material within the FRP category. Our carbon pipes are produced using the sheet winding method, which involves layering prepreg sheets and then heating and curing them to form the final product. 【Features】 ○ Lightweight (about 1/5 of steel) ○ High rigidity (up to about twice that of steel, depending on the type of CFRP fibers and layering orientation) For more details, please contact us or download the catalog.
