Glass Fiber-Epoxy Composites with Carbon Nanotube Fillers for Enhancing Properties in Structure Modeling and Analysis Using Artificial Intelligence Technique

Hybrid composite materials are a form of material thatincorporates morethan one type of reinforcement into a matrix to attain enhanced qualities.This usually includes the use of nanoparticle fillers in classic advancedcomposites with fiber reinforcements such as carbon or glass. In thecurrent investigation, the impact of carbon nanopowder filler on thewear and thermal performance of the chopped strand mat E-glass fiber-reinforcedepoxy composite (GFREC) were analyzed. Multiwall carbon nanotube (MWCNT)fillers were used; they react with the resin system to contributea significant improvement of properties in the polymer cross-linkingweb. The experiments were carried out employing the central compositemethod of design of experiment (DOE). A polynomial mathematical modelwas created using response surface methodology (RSM). To forecastthe wear rate of composites, four machine learning (ML) regressionmodels were built. The study's findings indicate that the additionof carbon nanopowder has a substantial impact on the wear behaviorof composites. This is mostly owing to the homogeneity created bythe carbon nanofillers in uniformly dispersing the reinforcementsin the matrix phase. Results revealed that a load of 1.005 kg, a slidingvelocity of 1.499 m/s, a sliding distance of 150 m, and 15 wt % offiller were found to be the optimal parameters for the efficient reductionof specific wear rate. Composites with 10 and 20% carbon contentsexhibit lower thermal expansion coefficients than plain composites.These composites' coefficients of thermal expansion fell by45 and 9%, respectively. If the carbon proportion increases beyond20%, so will the thermal coefficient of expansion.

The impact of carbon nanopowder filler on the wear and thermal performance of the chopped strand mat E-glass fiber-reinforced epoxy composite (GFREC) was analyzed in this investigation. The addition of carbon nanopowder has a substantial impact on the wear behavior of composites, mainly due to the homogeneity created by the carbon nanofillers in uniformly dispersing the reinforcements in the matrix phase. The optimal parameters for efficient reduction of specific wear rate were found to be a load of 1.005 kg, a sliding velocity of 1.499 m/s, a sliding distance of 150 m, and 15 wt% of filler.
