Method & Evidence

AimTo investigate the effectiveness of aqueous polymeric suspension prepregging with polyimide interphases in enhancing the interlaminar shear strength of PEEK and carbon fiber composites.

MethodComparative experimental study

ProcedureComposites were fabricated using two methods: hot compression molding and aqueous polymeric suspension prepregging. Specific polyamic acid (PAA) precursors, which transform into polyimides (PIs) and act as interphases, were synthesized and characterized. The interlaminar shear strength of the resulting composites was measured and compared between the two manufacturing techniques.
