3. In class, we covered the criteria for selecting a liquid precursor for C/C composites. Write each criterion, reword if necessary, to make it generally applicable to any of the liquid precursors we have discussed for the various CMC processes (SiC, oxide, and carbon matrices). Below is the discussed criteria in class, please use it to answer this question High carbon yield Minimal shrinkage during pyrolysis Easiest processability for all types of manufacturing routes like resin transfer molding (RTM), prepreg manufacturing, filament winding Low solvent content High degree of pre-polymerization with lowest viscosity Availability from multiple sources Low in costs High pot and storage life times
