This application discloses a clamping base for a hole-opening machine, belonging to the technical field of material processing equipment. It includes a fixed base and at least one movable base. The fixed base has a through hole with a positioning scale at the through hole. Support rods pass through both sides of the fixed base, and the fixed base is movably mounted on the support rods. The movable base is detachably mounted on the two support rods. This invention ensures the accuracy of the tool's position during hole opening through the positioning scale, achieving precise positioning of the opening location. The movable base prevents the fixed base from causing the tool to move arbitrarily during the opening process, ensuring opening accuracy. It is suitable for wood of different sizes and specifications. Operators can flexibly adjust the tool position of the hole-opening machine according to the actual position of the wood to be opened, enabling hole opening operations at different positions on the surface of the wood without repeatedly clamping the wood. This simplifies the operation steps, improves processing efficiency, and expands the processing range.

A method for preparing and applying a carbon fiber phthalocyanine sizing agent is disclosed. The method involves synthesizing a liquid phthalocyanine monomer containing siloxane segments through hydrosilylation and nucleophilic addition reactions, and then formulating it into a dilute solution-type sizing agent. Compared with existing technologies, this invention overcomes the limitation of traditional sizing agents relying primarily on physical compatibility with the resin matrix. Through an integrated "structure-function" design, the sizing agent simultaneously performs the dual functions of interface modification and resin co-curing. This sizing agent can form an active interface layer on the carbon fiber surface, co-curing with the phthalocyanine resin to form a chemically bonded network, increasing the interlaminar shear strength of the composite material by more than 30% and achieving a temperature resistance of up to 400℃, making it suitable for manufacturing high-temperature components for aerospace applications. The presence of a multidimensional conductive network on the carbon fiber surface endows the composite carbon fiber material with excellent electromagnetic shielding properties, and also improves the strength, toughness, and wear resistance of the carbon fiber.
