High-end carbon wheel manufacturing incorporates aerospace-grade hot isostatic pressing (HIP) technology. After prepreg carbon fabric layup, the material is placed in a high-pressure vessel and subjected to 100-150 MPa isostatic pressure at a temperature range of 120-150℃. This process improves resin flow by 40% and reduces interlaminar porosity to below 0.3%. The core breakthrough lies in the three-dimensional pressure system that uniformly compresses the material, resulting in a rim cross-sectional density difference of <1.5%. X-ray scanning of the finished product shows no delamination defects, and impact tests indicate that HIP-formed rims exhibit a 35% improvement in fracture resistance compared to traditionally hot-pressed rims.
