The objective of this research was to evaluate mechanical and thermal performance of a commercial adhesive with the incorporation of renewable-based nanomaterials. Renewable-based CNTs (carbon nanotubes) were synthesized using microwave irradiation of pyrolyzed oat hulls biochar and ferrocene as catalyst. CNTs were mixed with epoxy adhesive and TEPA (tetraethylene pentamine) which were used as curing agents. In the evaluation of mechanical and thermal properties of the composites studied, the samples contained between 0.02-0.1 wt% of CNTs. All composites were cured during 2 hours at 60°C. Mechanical properties (tensile strength and modulus) were tested in a Universal Testing Machine and were evaluated according to ASTM D638. Thermal properties were evaluated using a Thermogravimetric Analyzer. Of the results obtained an improvement of mechanical and thermal properties were observed. Thus, the incorporation of renewable-based CNTs can be a suitable alternative both to reduce fiber reinforced polymer manufacturing costs and in the valorisation of waste biomass
