SCOPE These specifications define the performance requirements for a heat curing, epoxy/ fiberglass laminate, supplied in die cut form with a release paper backing. 2. APPLICATION The materials released to these speci

4、fications were originally released to reinforce and stiffen sheet metal body panels. WSS-M11P64-A1 can be applied to electrocoat primed steel surfaces. WSS-M11P64-A2/A3 can be applied to oily cold rolled steel and galvanized steel surfaces. Recommended bake schedule per para 4.2. Materials are requi

5、red to perform in a number of applications. Each design and/or application has unique requirements. Compliance with this specification does not guarantee that material will function for all potential applications on vehicles. Selection of the appropriate material should therefore be based on jury ev

6、aluations or other test procedures as well as required functional trial. 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. Tests must be conducted on material having an original epoxy/fiberglass material thickness of 1.27 +/- 0.1 mm. 3.1 APPRO

7、VED SOURCES This specification requires the use of approved sources. Only the sources identified on the Ford Approved Source List (ASL) can be used when this specification is listed on the drawing, CAD file, or other documents. The list of approved sources is located within Ford at or available ext

8、ernally through a Ford Materials Engineer. 3.2 SYSTEM COMPATIBILITY Initial laminate approval was based on a specific material system which included the substrate, stamping lubricants and laminate. The originally approved material system was oven cured using specific production process parameters. S

9、ubstrate choice, stamping lubricants, stamping plant processing conditions and assembly plant processing conditions may affect laminate performance. If any of these parameters are changed, the laminate performance must be validated using the new parameters. ENGINEERING MATERIAL SPECIFICATION WSS-M11
