This invention relates to the field of composite material preparation technology, specifically to a method for preparing continuous glass fiber reinforced polyurethane core profiles, comprising the following steps: preparing continuous glass fiber, isocyanate component, polyol component, chain extender, coupling agent, catalyst, antioxidant, and ethanol, wherein the isocyanate index of the isocyanate component and the polyol component is 0.8-1.1. This invention effectively solves many defects of existing technologies by constructing a multi-dimensional synergistic optimization system, possessing significant technical advantages and practical value. Regarding interfacial bonding, a composite modification method is adopted, which significantly improves the interfacial bonding strength between the fiber and the polyurethane matrix, fundamentally improving the conduction efficiency of the material's mechanical properties, resulting in a significant improvement in the material's core mechanical properties such as tensile, bending, and impact resistance.

This utility model relates to the field of gear processing technology, specifically to a tooling for loading gear parts for carburizing and quenching. Through the setting of a height adjustment component, the spacing between the support rods can be adjusted according to the size of the gear. The two ends of the gear hanger are inserted into the hanger limiting grooves of the front and rear support rods. The hanger limiting grooves are evenly distributed to ensure the gear hanger is horizontally stable. Limiting blocks are installed at both ends of the gear hanger via threads. The diameter of the limiting blocks is larger than the hanger limiting groove to prevent the gear hanger from falling out of the groove. Gear parts are sequentially fitted onto the gear hanger, with the gear inner hole and gear hanger having a clearance fit. The teeth of each gear are inserted into the corresponding gear limiting groove. The gear limiting grooves are evenly spaced to avoid contact between gears, ensuring the tooth surface is fully exposed. The carburizing medium can fully coat the tooth surface. Furthermore, the gear hanger is used for batch loading and unloading. After quenching, the gear hanger can be tilted to quickly remove the gear.
