Impact Resistance and Residual Strength of Carbon Fiber Epoxy Laminates with Vertically-Aligned Carbon Nanotube Interfacial Reinforcement


Laminated carbon fiber composites are susceptible to delamination and fiber breakage when subject to impact, which in turn reduces their residual strength. This can severely reduce the service life of composite components in many industries, from aerospace to sporting goods, and cause designers to add part thickness and weight in areas of the structure where impacts are likely. Vertically aligned carbon nanotube (VACNT) forests are added to conventional unidirectional prepregs to: reinforce the interlaminar region between plies; reduce propagation of impact damage at ply interfaces; and increase compression strength post impact. Three composite systems, Newport 34-700/NCT301, Tencate IM7/TC350-1, and Hexcel IM7/8552, underwent ASTM D7136 [1] and D7137 [2] impact and compression testing. In all cases, VACNT reinforcement improved the residual strength of the composite after severe impacts by 11 – 16%. Characteristic impact damage of conventional fiber-reinforced polymer (FRP) composites and VACNT-toughened FRPs are compared.
