MULTIPLE-RESIN COMPOSITE STRUCTURES AND METHODS OF PRODUCING THE SAME Solid, flexible composite structures may include a textile arrangement (12) of at least one textile layer (22) constructed of textile fibers (16) and having a distribution of pores (30) formed therein, with a first resin (14) filling pores (32) having a pore diameter equal to or less than a pore diameter threshold, and a second resin (16) bonded to the first resin (14) and substantially filling pores (34) having a pore diameter greater than the pore diameter threshold. Some embodiments include a rigid first resin (14) such as an epoxy, and a flexible second resin (16) such as a silicone. Methods of producing composite structures (10) may include selectively filling, in a textile layer (22) having a number of pores (30) formed therein, only those pores (32) having a pore diameter equal to or less than a pore diameter threshold, with a first resin (14), and substantially filling the remaining pores (34) in the textile layer with a second resin (16).
