Five Chinese core material makers gain ground in composites

A cluster of Chinese suppliers is expanding in the composite core materials market as demand rises in marine, wind energy, transportation and aerospace. The five companies highlighted include CINON, Tiansheng, BeeCore, AXICOMB and Pentapur. Why it matters: - Composite core materials help manufacturers cut weight while improving stiffness and process efficiency in sandwich structures. - Demand is rising across marine, wind turbine blades, transportation panels, aerospace structures, electric vehicles and offshore wind. - Chinese suppliers are gaining share by adding capacity, product variety, technical support and certifications for export markets. What happened: - Five Chinese companies were highlighted as notable suppliers for composite core materials used in boat building, wind energy, transportation and aerospace. - The companies are Guangdong Cinon New Material Technology Co., Ltd. (CINON), Changzhou Tiansheng New Materials Group Co., Ltd., Jiangsu Beecore Honeycomb Technology Co., Ltd. (BeeCore), Aoxing Yabo (Tianjin) Technology Co., Ltd. (AXICOMB) and Anhui Pentapur Composites Co., Ltd. (Pentapur). - The release frames the market as a structural shift toward suppliers with consistent quality, technical support and broad product portfolios. The details: - CINON was founded in 2022 and is headquartered in Guangzhou. - CINON operates a 40,000 m² manufacturing facility and says annual output capacity reaches 1,200,000 m². - CINON’s product lineup includes PVC Foam Core, PMI Foam Core, PET foam core, PP honeycomb sheet, aramid honeycomb and infusion core materials. - CINON’s materials are used in marine and yacht building, wind energy, transportation, RV and caravan, aerospace and UAV, and industrial composites. - CINON holds ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 certifications. - CINON exports 100% of output to Europe, North America and Asia-Pacific. - CINON provides OEM services, technical support and a 15- to 30-day lead time. - CINON lists its website as company website . - Tiansheng was established in 1999 and is listed on the Shenzhen Stock Exchange under stock code 300169. - Tiansheng makes structural foam core materials including PVC, PET and PMI foams. - Tiansheng serves wind turbine blade manufacturing, marine, transportation and construction sectors. - Tiansheng operates multiple production bases and reports annual foam core capacity above 500,000 m³. - Tiansheng is known for proprietary formulation technology and high-volume production. - BeeCore is based in Jiangsu province and focuses on aluminum, aramid and polypropylene honeycomb core materials. - BeeCore’s honeycomb products are used in aerospace interiors, high-speed train panels, marine bulkheads and architectural cladding. - BeeCore emphasizes continuous bonding technology and custom cell sizes and thicknesses. - BeeCore exports heavily to Europe and Southeast Asia. - AXICOMB is headquartered in Tianjin and specializes in aluminum honeycomb core and composite panel solutions. - AXICOMB supplies transportation, marine and industrial sectors, including shipbuilding, rail vehicles and container floors. - AXICOMB is known for high-precision machining and rapid prototype turnaround. - Pentapur is located in Anhui province and makes crosslinked PVC foam, PET foam and structural core materials. - Pentapur supplies wind energy, marine and transportation applications. - Pentapur’s products are certified under DNV-GL and Lloyd’s. - Pentapur supplies major wind blade manufacturers and boat builders in China and abroad. - The article cites CINON’s CM core mat with dry weights from 125 to 360 g/m² and thicknesses up to 6 mm as widely used in boat hulls and decks. - The article says CINON’s CX infusion core material and CS general-purpose core help with resin flow in marine and transportation panels. - PET foam cores with densities from 80 to 320 kg/m³ are presented as recyclable solutions for wind energy and RV panels. - PMI foam cores with densities from 40 to 130 kg/m³ are presented as lightweight options for UAV structures and high-performance marine components. - PP honeycomb sheets with thicknesses from 5 to 100 mm are gaining traction in RV and industrial composite panels because of moisture resistance and impact performance. Between the lines: - The list suggests Chinese suppliers are competing on both scale and specialization, rather than on price alone. - Export-oriented certifications and technical support appear to be key differentiators for winning global composite contracts. - The focus on recyclable and lightweight materials reflects broader pressure from EV, renewable energy and aerospace buyers. What’s next: - Demand for core materials is expected to stay strong as lightweight structures expand into electric vehicles, offshore wind and advanced air mobility. - The five profiled companies are positioned as sourcing options for buyers evaluating boat building, wind blades, transportation panels and aerospace structures. - Composite manufacturers will likely continue looking for suppliers that combine production capacity, certification and application support.**
