A DURABILITY AND ADHESION TEST FOR FABRIC COVERED PLASTIC PARTS

摘要

The cross-cut adhesion test provides a rating for the adhesion of a surface material to a plastic substrate. The original ASTM standard D3359-02 for the cross-cut adhesion test was developed to measure the adhesion between thin paint films and flat, metal substrates. This test, however, is not well suited for three dimensional plastic parts that are covered with fabric. It will be shown in this study that improper cross-cut testing protocol can result in false failures and artificially low adhesion performance scores. A modified cross-cut adhesion test procedure is documented here that is based on the ASTM method and is applicable to fabric covered parts.
