I achieve positive, accurate placement of Z-pins in resin composite parts using a tool to guide the pins from the foam preform into the part. The tool has a reciprocating piston for crushing the foam to insert the pins and uses a positive stop to control penetration depth and positioning of the Z-pins. The tool also includes a plurality of bores for guiding the individual pins from the foam preform to the part while separating the part from the foam preform.

[ I claim:] [1.] A method for inserting a plurality of Z-pins to provide Z-direction fiber reinforcement into a resin composite part from a foam preform, comprising the steps of:(a) seating the preform on a positioning tool to align bores on an entry side in the positioning tool with the Z-pins of t

[ I claim:] [1.] A method for inserting a plurality of Z-pins to provide Z-direction fiber reinforcement into a resin composite part from a foam preform, comprising the steps of:(a) seating the preform on a positioning tool to align bores on an entry side in the positioning tool with the Z-pins of the preform;(b) positioning the part adjacent to the bores on an egress side of the positioning tool; and(c) driving the Z-pins through the bores of the positioning tool into the part by compressing the foam between a piston and the positioning tool.
