The major goal of this article is to evaluate the effects of multi-walled carbon nanotubes (MWNT) on ablation performance of carbon/phenolic nanocomposites. MWNT will be blended into phenolic resin using high-shear mixing technique to ensure exfoliation of nanoparticles. Loadings of 0,1, 2, and 3wt% of MWNT will be dispersed in the phenolic resin. Test panels of 120- x 120- x 12.6-mm carbon reinforced composites will be manufactured from prepregs using compression molding- Test specimens will be cut into proper size by using abrasive water-jet cutting. Further, simulated solid rocket motor (SSRM) testing facility will be used to examine ablative properties of these phenolic-MWNT nanocomposites with flame temperature about 2,200° C. These results will be compared to an industry standard ablative MX-4926 MC (carbon phenolic composite) manufactured by Cytec Engineered Materials. Control composites (Owt% MWCNT) were manufactured using prepregs and compression molding. Preliminary studies were conducted using radiant heat panel at heat flux of 15 kW/m2. These results demonstrated promising results. This oaper mainly discusses manufacturing method and radiant panel testing on control composites.
