ABSTRACT:
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.
