Jiangsu Aosheng Composite Materials Technology Co., Ltd. is a Suzhou-based carbon-composite company whose current corporate website and 2026 China Composites Expo listing support carbon-fiber woven and hybrid fabrics, prepreg, wind-blade pultruded plate and composite application development. The official site also presents automotive, sports, hydrogen, aviation and overseas footprints under the Aosheng group. GetFRP therefore assigns measured-demand phrases such as carbon fiber fabric, carbon fiber plate, pultruded, resin infusion and vacuum infusion only where a published product or manufacturing route supports them. Fishing rods may be an end use of prepreg, but they are not listed here as an Aosheng finished product. Likewise, automotive parts, sports products and hydrogen cylinders are marked as group-sector inquiries rather than automatically attributed to the Jiangsu parent factory. Buyers must confirm the exact legal entity, production site and specification behind a quotation. Awards, customer relationships, capacity, CNAS, patent and standards-participation statements on the website remain company claims, not GetFRP verification.

HS Hyosung Carbon Materials (Jiangsu) Co., Ltd. is the HS Hyosung Advanced Materials carbon-fiber entity in Xinyi, Xuzhou, Jiangsu. China Composites Expo lists the current Chinese entity. The group's current global-network page identifies HS HYOSUNG Carbon Materials (Jiangsu) Co., Ltd., its Xinyi Economic Development Zone location, telephone and Carbon Fiber product line. The official TANSOME page publishes standard-modulus 6K, 12K and 24K, intermediate-modulus 12K and 24K and ultra-high-tensile 12K fibers, with high-pressure vessel, cable-core, aerospace, wind, sports, industrial and construction uses. Public company reporting dates the Jiangsu entity to 2022 and says an expanded carbon-fiber line began operation in 2024. This profile connects the group portfolio to the identified Jiangsu manufacturing entity, but does not transfer the Korean group's full history, total capacity, certifications or every grade into verified Jiangsu-site capacity, approvals or design values.

Liaoning Yuwei Technology Co., Ltd. says on its current official website that it was founded in 2009 in Liaoyang and develops and produces specialty epoxy resins and reactive diluents. The published range explicitly covers phenoxy, hydrogenated bisphenol-A, heat-resistant multifunctional, dimer-acid-modified, brominated, halogen-free flame-retardant, crystalline and bisphenol-A liquid and solid epoxies, plus multiple glycidyl-ether diluents. Composite adhesive and reinforcement material is one published application. China Composites Expo's L directory retains the legacy exhibitor name Liaoyang Xinyu Chemical Co., Ltd. The domain and business range provide a research trail, but the current website does not publish a legal name-change or succession document. GetFRP therefore builds the profile for the current Yuwei entity and does not state that the two names are a proven identical legal person. Capacity, patent, management-system and performance statements are company-published; certification fields remain empty until current certificates are matched to entity, site, scope and validity.

Liaoning Meituo Technology Co., Ltd. describes itself on its current official website as a manufacturer of aluminum-alloy and other metal high-pressure cylinders, composite high-pressure cylinders, metal pressure-vessel liners and related products. The site dates the company to 2010 and locates it in Liaoning's Shenfu Demonstration Zone. Its published range includes carbon-fiber overwrapped composite cylinders, vehicle hydrogen cylinders, industrial specialty-gas and sampling cylinders, breathing-air, medical, diving, recreational, food-and-beverage and fire-extinguisher cylinders, plus aluminum liners. The China Composites Expo L directory supplies the exhibitor trail. Carbon fiber is the reinforcement in Meituo's composite-cylinder offer; the company is not presented here as a supplier of carbon-fiber tow, fabric, prepreg or generic carbon products. Performance, standard, certification, customer and export statements remain company-published claims. Qualification must match the quoted model, volume, pressure, liner and overwrap architecture, manufacturing site and destination-market approval evidence.

Lianyungang Weide Composite Materials Facilities Co., Ltd. says on its current official website that it was established in 2001 and develops and manufactures composite-production equipment. The published range covers continuous-filament-winding FRP pipe lines, high-pressure hydrogen-cylinder winding lines, four-axis and horizontal winding machines, high-pressure epoxy-pipe lines, centrifugal-casting GRP pipe lines, lighting-pole lines and supporting manipulators, curing ovens, resin-supply, intelligent feeding, conveying, joint-making and quality-assurance systems. China Composites Expo's L directory lists the matching exhibitor. Weide sells the machinery used to make pipes, cylinders and poles; those outputs are not presented as Weide-manufactured FRP or carbon-fiber products. GetFRP therefore excludes reinforcement, FRP-pipe and finished-cylinder supplier keywords. Capacity, performance, import-substitution, service-life and mechanical-property statements are supplier claims that must be validated against the quoted configuration, representative trials, FAT, SAT and contractual acceptance records.

Ningbo Motong Composite Materials Co., Ltd. presents an integrated product, process, mold, equipment and line-development offer for series production of continuous-fiber composites. Its current official website describes non-preforming integrated prepreg compression molding (PPCM), hybrid CFRP or GFRP molding with metal, sandwich molding with paper fiber, foam, honeycomb or aramid, and a complete Type IV hydrogen-cylinder forming-process package covering liner, boss connection, high-speed low-carbon winding and rapid curing. SMC, HP-RTM and autoclave are listed as technology reserves. China Composites Expo independently lists the Ningbo company in its N directory. GetFRP treats these as engineering, process and line solutions. CFRP, GFRP, prepreg, metals and core materials are process inputs, while the Type IV vessel is a process-package target; none is presented here as Motong's standard raw-material or finished-cylinder catalog.

Lianyungang Tuotian Aviation Equipment Co., Ltd. is presented on its official website as a core subsidiary of Lianyungang Zhongtong Group and a developer and manufacturer of high-performance composite-processing equipment. The company publishes a roughly 30,000 m² production base with six specialized workshops and an industrial chain extending from R&D through serial manufacture. Its equipment serves pipe, hydrogen-cylinder and other pressure-vessel, utility-pole, tank, composite-shell and pultruded-product applications.
