[57] Abstract: Solid, flexible composite structures may include a textile arrangement of at least one textile layer constructed of textile fibers and having a distribution of pores formed therein, with a first resin filling pores having a pore diameter equal to or less than a pore diameter threshold, and a second resin bonded to the first resin and substantially filling pores having a pore diameter greater than the pore diameter threshold. Some embodiments include a rigid first resin such as an epoxy, and a flexible second resin such as a silicone. Methods of producing composite structures may include selectively filling, in a textile layer having a number of pores formed therein, only those pores having a pore diameter equal to or less than a pore diameter threshold, with a first resin, and substantially filling the remaining pores in the textile layer with a second resin.
