Soric is a flexible core material and flow medium. It is a pressure-stable nonwoven polyester material with with a compression resistant cell structure. designed to enable resin flow in infusion processes. These pressure-resistant cells, which are separated by channels, contain synthetic micro-spheres. The cells do not absorb resin and therefore limit the total resin up-take

The cells are filled with microspheres to enable reduction of resin absorption and resist compression. The nonwoven channels between cells enable resin transport and provide adhesive bonding between the sandwich faceskins and Soric core. Soric flexible core can be used with most typical resins and closed molding processes.
