Prepreg Composite Processing


Model No. CP-1000

Solvent (solution) type prepreg making systems saturate reinforcements with resin dissolved in a solvent which decreases its viscosity and aids fibers’ complete wet-out.  Single roving is guided through guide bars to achieve appropriate tension, run through a resin bath, lead through a set of rollers to remove excess resin and winded around the drum just like filament winding. it controls automatically the fiber areal weight [FAW]. This machine can easily make a sample prepreg and specimen to test mechanical properties when we modified resin component and carbon fiber producing method. It is an excellent solution for the laboratories and research institutes that are developing and testing new prepreg material.
