01 Development of Tow Prepregs with Improved Heat Resistance and Mechanical PropertiesA key trend in the global tow prepreg market is the ongoing development of products with improved heat resistance and mechanical properties to meet the demanding needs of sectors like aerospace, automotive, and defense. Manufacturers are focusing on imprving the performance of tow prepregs under extreme conditions while maintaining lightweight characteristics.A 2025 study published in Elsevier introduced a novel Tow-Preg Cladding (TPC) method, enabling the additive manufacturing of continuous carbon fiber/epoxy composites with a structured core-shell design. This approach achieved a fiber volume fraction exceeding 50%, resulting in impressive mechanical properties: tensile strength of 1295.72 MPa, compressive strength of 544.13 MPa, and flexural strength of 659.30 MPa. The dual-cure cladding and in-situ epoxy impregnation processes contribute to enhanced thermal stability and structural integrity, making them suitable for aerospace and automotive applications.Such innovations highlight the market's direction toward advanced, application-specific tow prepreg solutions.
