Which outcome occurs when an epoxy resin is inadequately mixed with its hardener during composite manufacturing?

💡 Explanation

When the epoxy resin is poorly mixed, incomplete crosslinking polymerization occurs because insufficient reactive sites results in shorter polymer chains with weaker van der Waals bonding and incomplete covalent bond formation. Therefore reduced glass transition temperature results, rather than increased adhesion, decreased the absorption rate, or strength enhancements which depend on a complete robust polymer matrix.
