2、R HOOK AND PILE FASTENERS NOT TO BE USED FOR NEW DESIGN 1. SCOPE This specification defines the performance of a pressure sensitive adhesive applied to woven or molded nylon tape fasteners. 2. APPLICATION The adhesive bonded hook and pile fastener tape was originally released to attach the panel ass
3、embly - package tray to the painted upper back panel sheet metal. Compliance with the performance requirements of this specification does not guarantee adhesive bonded hook and/or pile fasteners will function for all applications within the vehicle. The specific substrates, environments, and load co
4、nditions must be considered when evaluating each design concept. 3. REQUIREMENTS 3.1 CONDITIONING All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 C and 50 +/- 5 % relative humidity for 24 h prior to testing, and tested under the same controll
5、ed conditions. 3.2 INFRARED SPECTROPHOTOMETRY Ford Motor Company, at its option, may conduct infrared analysis of material/parts supplied to this specification. The spectra established for initial approval shall constitute the reference standard, and shall be kept on file at Ford. All samples shall
6、produce spectographs that correspond to the reference standard when tested under the same conditions as those specified on the master spectra. 3.3 PEEL ADHESION, min. N/mm The minimum adhesion values indicated shall be obtained when test specimens are bonded to the substrates indicated in para. 5.2,

9、 Method: Prepare five samples per exposure. Test per ASTM D1000 except: . Wipe painted and plastic substrates with a lint free rag; wipe plain CRS panels with isopropyl alcohol. . After completing exposure test specimens shall be conditioned at 23 +/- 1 C for a minimum of 1 h and a maximum of 3 h pr

Prior to conducting 180 peel tests, apply masking tape to the hook or pile side of the non-bonded end of the tape. This prevents the hook or pile surfaces from conta
11、cting during the peel procedure, which may result in erratic test values.

13、by bonding a 25 x 50 mm strip of each type fastener tape noted in para. 5.3 to a 25 x 50 mm panel of each substrate described in para. 5.2 - see Fig. 1. Clean substrate panels per para. 3.3. Prepare 3 test samples per exposure. Secure each bond by applying a (4.54 kg) weight for 15 seconds. Scribe a
14、 line across top of each test strip. Condition bonded assembly 24 h 15 23 +/- 2 C. Test Method: Hang test panels in a vertical position in a humidity cabinet or mechanical convection oven set at prescribed exposure conditions. Gently attach a 227.0 gr weight to the unbonded end of each tape sample.
15、Weights should be secured in such a manner that the shear loads on the bond lines are applied perpendicular to the bottom edge of the substrate panel. After 100 h exposure measure the amount the tape strip has been displaced on the substrate panel. 3.5 ACCELERATED ENVIRONMENTAL AGING TEST - VEHICLE

Changes in formulation o
21、r processing shall not be made without prior approval as described in Supplier Procedure I-A. 4. APPROVAL OF SUPPLIERS Suppliers to this specification must be approved by the affected product engineering office. Procedure for gaining approval of a specific material to a new/existing ES-M specificati
22、on is contained in Supplier Procedure I-A. Approved new suppliers will be added to the engineering materials approved source list. 5. MATERIAL BACKGROUND The hook and pile tape fasteners originally utilized mechanical methods for attachment to the substrate, i.e., sewn, stapled, riveted, screwed, et
23、c. Recent designs dictated development of a pressure sensitive adhesive for bonding the hook and pile details to various substrate materials.
