Multiple-resin composite structures and methods of producing the same

摘要

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.

主权项

1. A composite structure, comprising:
a textile arrangement of at least one textile layer, the textile layer constructed of textile fibers and having a single distribution of pores formed therein, the single distribution of the pores consisting of intra-fiber pores within individual textile fibers and inter-fiber pores between the textile fibers; a first resin filling all of the intra-fiber pores of the single distribution of the pores and also those inter-fiber pores of the single distribution of the 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 those inter-fiber pores of the single distribution of the pores having the pore diameter greater than the pore diameter threshold.
