Core advantages: triple guarantee of excellent performance, flexible customization, and full scene adaptation

1. 36GPa high modulus core performance, laying the foundation for the reliability of load-bearing structures

The core competitiveness of UIN-36T unidirectional carbon fiber prepreg lies in its fiber modulus of 36GPa, which enables it to achieve higher stiffness with lighter weight in load-bearing structural components, and is compatible with medium to high strength scenarios of 30T unidirectional carbon fiber prepreg, making it more widely applicable. The unidirectional fiber arrangement design (with a fiber direction consistency of 99.8%) maximizes the release of the axial mechanical properties of carbon fibers. After authoritative testing, the product's 0 ° tensile strength can reach over 2600 MPa, which is 28% higher than that of ordinary 30T unidirectional carbon fiber prepreg; The bending strength exceeds 2000MPa, and under long-term dynamic loads such as aircraft flight vibrations and high-speed car bumps, the fatigue strength retention rate still exceeds 88%, far exceeding the industry average of 80%, ensuring the stability of the core structural components in long-term service.

At the same time, the product density is strictly controlled at no less than 5% to ensure that carbon fibers are evenly distributed in the prepreg, without any weak performance points caused by local fiber sparsity. Taking the aircraft wings in the aerospace field as an example, after using UIN-36T unidirectional carbon fiber prepreg, the weight of the components is reduced by 48% compared to traditional aluminum alloys, while the stiffness is increased by 35%, directly reducing aircraft fuel consumption and takeoff load; In the application of high-pressure vessels in industrial equipment, their high-strength characteristics can reduce the wall thickness of the vessel by 28% and increase the pressure tolerance to over 45MPa, balancing safety and lightweight requirements.
