Interlaminar Shear and Tensile Strength: Comparison between CNT Films/epoxy and CNT Films/PVA composites
Carbon nanotubes (CNTs) thin sheets/films demonstrate excellent mechanical, thermal and electrical properties.Their mechanical properties can further be enhanced with the incorporation of high-performance polymers in the form of composites for high performance materials.However, the resultant performance is highly dictated by compatibility of CNTs within the polymer matrix.Herein, CNT composites based on polyvinyl alcohol (PVA) and epoxy resins fabricated via vacuum assisted resin transfer molding (VARTM) technique were studied.Their interlaminar and tensile strength were compared.The composites containing CNT films/epoxy exhibited significantly higher peeling strength (633.7 N/m) compared to those with PVA (70.8 N/m) signifying durability.Conversely, the tensile strength of CNT film/PVA (452.24 Mpa) was better than CNT films/epoxy composites (332.8 Mpa).We note improved mechanical properties of the composites compared to pure CNT films.
