2、FRP AND FRP/PAINTED METAL PARTS ASSEMBLED AFTER VEHICLE ELECTROCOAT 1. SCOPE This specification defines the adhesion requirements for an adhesive or an adhesive system suitable for structur ally bonding FRP/FRP and FRP/painted metal assemblies. 2. APPLICATION This specification was released original

3、ly for adhesives used to structurally bond glass fiber reinforced polyester (FRP) and painted metal reinforcements. These adhesion requirements cover assemblies consisting of FRP to FRP and FRP to painted metal substrates. Adhesives meeting these requirements can be applied on body components assemb

4、led after vehicle electrocoat. This specification does not describe initial adhesive cure conditi ons. The procedures for assembly bonding shall be prescribed in accordance to adhesive manufacturer and part supplier recommendations. Compliance with this performance specification does not guarantee t

5、he structural adhesive will function for all potentia l applications on a vehicle. The specific design condition should be evaluated by a plant trial or laboratory simulation prior to release of the material. 3. REQUIREMENTS 3.1 STATISTICAL PROCESS Suppliers must conform to the requirements of Ford

6、Qualit y System Standard Q - 101. A mutually acceptable Control Plan as described therein is required for material/source approval. Appropriate statistical tools must be used to analyze process/product data so that variation in the final product is continuously r educed. 3.2 INFRARED SPECTROPHOTOMET

7、RY AND/OR THERMAL ANALYSIS Ford Motor Company, at its option, may conduct infrared and/or thermal analysis of material/parts supplied to this specification. The IR spectra and thermograms established for initial approv al shall constitute the reference standard and shall be kept on file at the desig

8、nated material laboratory. All samples shall produce IR spectra and thermograms that correspond to the reference standard when tested under the same conditions.
