Manufacturing process of composite material laying tape of embedded co-curing continuous presoaking damping film

Abstract

The invention discloses a manufacturing process of a composite material laying tape of an embedded co-curing continuous presoaking damping film. The manufacturing process comprises the following steps: 1) preparing raw materials; 2) preparing gross rubber; 3) preparing viscoelastic damping material solution; 4) conducting presoaking process of at least once for a presoaking material of a composite material by utilizing a viscoelastic damping material prepared in the step 3) to produce the presoaking material of the composite material with a damping film; meanwhile, utilizing a wet-type drying process or a process combining wet-type drying with dry-type drying for change No.120 gasoline into gaseous gasoline, cooling the mixture of the gaseous gasoline and steam through a heat exchanger, and then sending the cooled oil-water mixture into an oil-water separator to separate and recycle the No.120 gasoline; and 5) embedding the presoaking material of the composite material with the damping film manufactured in the step 4) into a composite material structure as a specific laying layer, placing the mixture into a vacuum bag of a hot pressing tank together, and highly vacuumizing so as to complete the preparation of an embedded co-curing composite material damping structure workpiece by using a co-curing process.

Description

technical field [0001] The invention relates to material technology, in particular to a composite material tape laying process for an embedded co-cured continuous prepreg damping layer, and belongs to the field of research on dynamic modification of composite materials. Background technique [0002] The damping characteristics of the composite structure itself are 10-100 times higher than that of common metals, but this is still low in applications. However, the designability of the mechanical properties of composite materials creates a broad space for further improvement of its damping performance. Embedded co-cured composite material damping structure is a multiphase solid compounded by three different materials (such as carbon fiber, resin and viscoelastic damping material) through physical or chemical methods through artificial or modern technology. Its matrix phase, reinforcement phase and viscoelastic damping material play a coordinated role in performance, so as to ac...
