Abstract

The invention discloses a forming device and method for a T-shaped composite material part with high resin fluidity, and relates to the field of composite material part manufacturing. The forming device comprises a bottom plate, a fixed core mold, a movable core mold, a uniform pressing plate, a positioning adjusting assembly and a plurality of sealing rubber strips, the fixed core mold is fixed on the bottom plate, the movable core mold is movably installed on the bottom plate through the positioning adjusting assembly, a first inverted-L-shaped groove is formed in the side, close to the movable core mold, of the fixed core mold, a second inverted-L-shaped groove is formed in the side, close to the fixed core mold, of the movable core mold, the first inverted-L-shaped groove and the second inverted-L-shaped groove are symmetrically formed and are the same in structure, the multiple sealing rubber strips are used for being arranged on the bottom of the vertical section and the periphery of the horizontal section of the T-shaped composite material part with high resin fluidity, and the uniform pressing plate is used for being placed on the top of the T-shaped composite material part with high resin fluidity. The forming device and the forming method can effectively control the flowing behavior of the resin in the curing process, ensure the internal quality, and are simple to use, convenient to demold and low in cost.

Description

technical field [0001] The invention relates to the field of composite material part manufacturing, in particular to a molding device and a molding method for a T-shaped composite material part with high resin fluidity. Background technique [0002] Thanks to its excellent comprehensive performance, fatigue resistance and strong designability, in recent years, composite material parts (assemblies) have been widely used in aviation, aerospace, navigation and other fields, and their design and manufacturing levels have been rapidly increasing. promote. [0003] In order to further reduce the weight, simplify the assembly relationship, and give full play to the advantages of strong designability of composite material parts, it has become the development trend of composite material parts to integrate multiple traditional parts into one and give parts more structural functionality. T-shaped composite material parts are typical representatives of this trend, and its application e...
