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 Z-pin positioning tool for accurately and reliably inserting Z-pins from a pin-carrying foam into a resin composite part, comprising:(a) a reciprocating piston slidingly engaged in a housing;(b) a removable pin placement member temporarily rigidly fixed in the housing to form one

[ I claim:] [1.] A Z-pin positioning tool for accurately and reliably inserting Z-pins from a pin-carrying foam into a resin composite part, comprising:(a) a reciprocating piston slidingly engaged in a housing;(b) a removable pin placement member temporarily rigidly fixed in the housing to form one end wall of the housing and to define a cavity in the housing between the piston and pin placement member for receiving the pin-carrying foam, the pin placement member including a plurality of bores extending through the member in a regular pattern the bores extending from an outer face on a surface adjacent to the cavity and a part receiving face on a surface opposite the cavity so that the bores define a pin placement orientation in a part seated on the receiving face and for guiding pins in the foam into the part upon crushing motion of the piston against the foam;(c) motive means for moving the piston toward the member to crush the foam to insert the pins from the foam through the bores into the part; and(d) a part seat fabricated into the receiving face of the pin placement member adapted for seating the part for insertion of the Z-pins from the pin carrying foam through the bores during motion of the piston toward the member.
