Description

Technical Field

[0001] This utility model relates to the field of dissolution device technology, specifically a dissolution device for composite prepreg samples. Background Technology

[0002] The aerospace industry has been searching for lightweight materials to improve fuel efficiency and performance, and prepregs hold great potential in aircraft manufacturing. Prepregs also have a broad market in the wind energy sector, particularly in the manufacture of wind turbine blades, as the high strength of composite materials makes them ideal for large and durable blades. Furthermore, due to their high strength and flexibility, prepregs show great promise in the sporting goods industry, including the manufacture of high-performance bicycles, tennis rackets, and other sporting products. In addition, composite materials are increasingly being used in bridges, buildings, and other infrastructure projects. The resin content of prepregs is a core physical performance indicator for evaluating prepreg quality, directly determining the mechanical properties and process adaptability of composite products.

[0003] Currently, when testing the resin content of prepregs, the solvent is usually added to a beaker and then ultrasonically stirred to dissolve it. Each stirring lasts about ten minutes, and the solvent is manually poured out after each test. A sample generally needs to be dissolved at least 3-5 times, which is time-consuming and laborious. In addition, because the reagent is an organic reagent, prolonged stirring and dissolving will release organic gases into the air, which will cause health harm to the test personnel.

[0004] Therefore, there is a need for a composite prepreg sample dissolution device that can automatically add and dissolve, automatically perform ultrasonic stirring, and automatically drain the liquid, making it more time-saving, labor-saving, and safer than traditional dissolution methods.

Piston cylinders 14, welded to the bottom wall of the inner cavity of the dissolving tank 1, are provided on both the front and rear bottom sides of the beaker 19. A piston rod 15 is slidably connected to the cylinder body of the piston rod 14, meaning the piston rod 15 can move up and down along the piston rod 14. An anti-detachment block 20 located inside the piston rod 14 is welded to the bottom end of the piston rod 15 to prevent the piston rod 15 from detaching from the piston rod.
