Abstract
A composite including a thermoplastic polyamide resin, multi-walled carbon nanotubes (MWCNTs), and seashells (SSs). The particles of the SSs have an average size of less than 100 micrometers (μm). The composite includes 80-99 wt. % of the thermoplastic polyamide resin, 0.1-1 wt. % of the MWCNTs, and 1-20 wt. % of the SSs, based on a total weight of the composite. The MWCNTs and particles of the SSs are dispersed in a matrix of the thermoplastic polyamide resin. The composite has a tensile strength of greater than 90 megapascals (MPa).

A composite, including:
- a thermoplastic polyamide resin;
- multi-walled carbon nanotubes (MWCNTs);
- and
- seashells (SSs),
- wherein particles of the SSs have an average size of less than 100 μm, and
- wherein the composite includes 80-99 wt. % of the thermoplastic polyamide resin, 0.1-1 wt. % of the MWCNTs, and 1-20 wt. % of the SSs, based on a total weight of the composite,
- wherein the MWCNTs and particles of the SSs are dispersed in a matrix of the thermoplastic polyamide resin,
