A review is presented on the testing and mechanical properties of continuous fibre reinforced composites modified with nanotubes or nanofibres either dispersed in the resin or grown on the microfibres. The nano-level cross-links are shown to be able to (1) increase the fibre/matrix interfacial strength, (2) reduce the inter-fibre crack growth, and (3) improve the inter-ply delamination resistance. A positive influence on the thermal expansion is also detected. However, for unfavourable material constitutions, the strength properties can stay almost the same or even significantly deteriorate.
