2、EAT CURING - EPOXY/GLASS FIBER LAMINATE, ESB-M2G281-A METAL REINFORCEMENT NOT TO BE USED FOR NEW DESIGN 1. SCOPE The material defined by this specification is a heat curing, epoxy/fiberglass laminate, supplied in die cut form. Construction consists of woven fiberglass mat onto an epoxy adhesive film

3、 release paper backed. 2. APPLICATION This specification was released originally for material used to reinforce and stiffen sheet metal body panels. This material can be applied to oily cold rolled steel, Zincrometal and galvanized steel surfaces. Recommended minimum material cure temperature is 182

4、 C for 8 min metal temperature. Material high temperature resistance permits application to body components exposed to electrocoat bake ovens. 3. REQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS

5、 Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.2 UNCURED MATERIAL PROPERTIES 3.2.1 Construction Construction shall consist of woven fiberglass mat onto an epoxy adhesive film, release paper backed. There shall be

6、 no loose glass fibers after die cut operation. 3.2.2 Thickness 1.27 +/- 0.1 mm or as (ASTM D 461, 85 g load, 25 mm specified on engineering diameter foot, total fiberglass drawing and adhesive) 3.2.3 Stiffness 2 - 20 MPa (ASTM D 747, without release liner) 3.2.4 Formability The material shall not d

8、 fall off from panel. Test Method: . Apply a 1.27 x 100 x 150 mm adhesive laminate strip to the center of a 300 x 300 mm metal panel of each substrate listed in para 4.2. . Pass a 2 kg roller over sample in one forward and reverse direction. . Invert panels immediately after adhesive application and

9、 condition at 23 +/- 2 C for 4 h minimum. . Save panels for Inverted Bake Test, para 3.3.2. 3.2.7 Phosphate Wash Resistance No evidence of material wash off or displacement due to precleaning or phosphating solutions in flow phosphate tanks. 3.2.7.1 Laboratory (FLTM BU 016-01, Method “A“) 3.2.7.2 Fu

10、nctional Materials being evaluated for initial approval to the specification shall be subjected to a production trial in an area intended for use. This trial will be conducted after all other specification requirements have been met including laboratory evaluation for flow phosphate wash resistance.

11、 3.2.8 Electrocoat Compatibility Shall not contaminate (FLTM BN 119-01, use current production electrocoat primer bath cause paints as identified by the Body. electrocoat film irregularities. Materials Engineering Office). 3.2.9 Storage Stability The material shall be stored in sealed packages conta

12、ining desiccant at temperatures below 32 C away from all sources of heat and sunlight. Heat greatly accelerates aging. Under these storage conditions, the shelf life of the material shall be 2 months. When these materials are stored at temperatures below 23 C, they shall be conditioned at room tempe

13、rature prior to application. Adequate conditioning permits the material to obtain its optimum application properties. Materials in opened packages shall be used within 72 hours. 3.2.10 Release Paper Adherence and Removal The release paper shall remain attached to adhesive surface during shipping and

14、 handling. It shall be easily removed from the adhesive without adhesive separation or paper tear.
