In accordance with the present invention, there is provided a method of inserting at least one Z-pin into a composite laminate for providing Z direction reinforcement thereto. The method comprises the initial step of positioning at least one Z-pin upon the composite laminate. Thereafter, an insertion force is applied to the Z-pin at a first level which is sufficient to commence an insertion process wherein the Z-pin is driven into the composite laminate at a first insertion speed. The insertion force applied to the Z-pin is continuously monitored, with the first insertion speed being reduced to a second insertion speed in response to a monitored increase in the insertion force from a first level to a second level.
