Composite structure for building material

A bio-based brick comprising a composite structure, the composite structure comprising:

• a fiber-based material comprising one or more of palm fibers, wood fibers, cork fibers, bamboo fibers, and agricultural waste, wherein the fiber-based material comprises greater than or equal to 1% and less than or equal to 60% of the composite structure by weight percentage;
• a silica filler comprising more than or equal to 1% and less than or equal to 90% of the composite structure by weight percentage;
• and
• a polymeric binder material comprising one or more of a resin, a vitrimer, a thermoset polymer, and a thermoplastic polymer, wherein the polymeric binder material comprises greater than or equal to 1% and less than or equal to 50% of the composite structure by weight percentage.

A method for manufacturing a bio-based brick, comprising:

• mixing a fiber-based material and a silica filler to form a dry mixture, wherein the fiber-based material comprises one or more of palm fibers, wood fibers, cork fibers, bamboo fibers, and agricultural waste, and wherein the silica filler comprises one or more of river sand, sea sand, desert sand, quarry dust, and manufactured sand;
• introducing a polymeric binder material into the dry mixture to form a wet mixture, wherein the polymeric binder material comprises one or more of a resin, a vitrimer, a thermoset polymer, and a thermoplastic polymer;
• and
• molding and/or curing the wet mixture to form the bio-based brick, wherein:
• the fiber-based material comprises greater than or equal to 1% and less than or equal to 60% of the wet mixture by weight percentage;
• the silica filler comprises greater than or equal to 1% and less than or equal to 90% of the wet mixture by weight percentage;
• and
• the polymeric binder material comprises greater than or equal to 1% and less than or equal to 50% of the wet mixture by weight percentage.
