Abstract
Continuous production of carbon nanotube-grafted-carbon fibres (CNT-g-CFs) was performed in an open chemical vapour deposition reactor, and the resultant fibres were used in single-fibre pull-out tests to determine their interfacial properties with epoxy, nanoengineered epoxy, and polypropylene matrices. At a single CNT-g-CF level, the presence of uniform carbon nanotube (CNT) coverage, sub-550 nm length, has been shown to increase the interfacial shear strength (IFSS) by 26% (98.4 ± 7.2 MPa) when compared to the baseline unsized carbon fibre (77.9 ± 5.1 MPa) embedded in a commercial epoxy. The IFSS increased when combining CNT-g-CF with a 2 wt.% multiwall carbon nanotube loaded epoxy matrix to 32% (102.8 ± 6.7 MPa) compared to the same baseline. In a polypropylene matrix, the presence of uniform CNT coverage on the carbon fibre surface also led to an increase in IFSS by 39% (11.2 ± 2.1 MPa) when compared to the unsized carbon fibre/polypropylene baseline (8.1 ± 1.5 MPa).
