Research On Mechanism And Experiment Of Epoxy Resin/Ommt Nanocomposites By High-Energy Liquid Shock Wave

Nanoparticles as a filler can effectively improve the performance of the polymer matrix composites. When nanoparticles are directly mixed with the matrix resin, it is difficult to disperse equality for its special properties. So it is difficult to achieve the purpose that nanoparticles could enhance and toughen resin. In this paper, a high-energy liquid shock wave pressure producer was used to prepare resin nanocomposites. The high-energy liquid shock wave pressure producer was composed of piezoelectric ceramic transducer and excitation power supply. The nanoparticles could be dispersed equably in resin by the action of shock wave, and then high-performance nanocomposites was prepared. Compared with other methods, shock wave method had many advantages, such as efficient, safety, good controllability, low cost. The high-energy liquid shock wave is a new way to prepare resin nanocomposites.In this paper, the EP/OMMT nanocomposites was made up of resin, OMMT and MeTHPA. And the mechanical properties and thermal properties were discussed in the paper. Compared with common ultrasound method, the nanocomposites which were prepared by shock wave method were proved effectively. Meanwhile the rheological behavior of EP/OMMT nanocomposites was investigated.The details as follows:1. The operating frequency of shock wave generator was computed by ANSYS, which is the frequency of shock wave generater.2. DSC was used to discuss the curing essence of nanocomposites. Kissinger method and Crane formula were count to the activation energy and the order of reaction of the system.3. The optimal craft of EP/OMMT nanocomposite by high-energy liquid pressure shock was determined. The nanocomposites which were prepared by shock wave method had better properties than the nanocomposites by normal ultrasound method. The shock wave method could shorten decentralized time and reduce cost of production, which is a new way to prepare resin nanocomposites.4. The high-energy liquid shock wave was used to prepare resin nanocomposites, which had high temperature, high pressure and high strain characters. The nanomaterials could be dispersed evenly at the function of the shock wave.5. The exfoliated and dispertion mechanism of OMMT under the shock wave was invested in the paper.
