11、h two different grades available for each based on density and material properties. Type I is an unreinforced, two (2) component urethane, reaction injection molded structural foam. Type II is similar except it is glass reinforced and includes two (2) grades with different glass content and density.
12、 The selection of the Type and Grade shall be made by Materials Engineering. 4.2.1 The rigid foam shall be a two component urethane, reaction injection molded behind the vinyl facing. Any remaining mold release residue must be compatible with Navistar paint repair systems and must have prior approva
13、l of Materials Engineering. 4.3 Finished Part Colors, textures, and finishes shall be called out within the material specification on the part drawing and shall match the approved standard samples in the files of the Industrial Design Department, at TDTC. 4.3.1 Finished part weight may not vary more
14、 than 10% from the approved sample. 4.4 Property And Performance Requirements 4.4.1 Rigid Foam The material properties of the foam are dependent on the density. When foam density varies outside the nominal limits, due to part and tool design, physical properties may also vary. Areas on the part wher
15、e density varies beyond the nominal limits shall be indicated on the part drawing, and preproduction qualification testing is required. See Table 1 for the required physical properties. 4.4.2 Adhesion 4.4.2.1 Vinyl: The vinyl to rigid foam bond shall meet the requirements of TMS-7028, Bonded Interio
16、r Trim Products. Production parts shall be used for testing adhesion. 4.4.2.2 Metal Inserts: Metal inserts shall be molded or bonded in place such that any attempt to remove the insert results in foam failure. Structural components shall meet TMS-6900 for bonding appropriately modified for the appli
17、cation (Interior components would be limited 50C for hot pulls, 70C heat aging, and humidity in place of salt spray). Please contact Materials Engineering for further guidance. 4.4.3 Heat Age Heat age parts for 168 hours at 70 C (158 F). 4.4.3.1 Required Parts shall meet the physical properties, as
18、listed in Table 1, and the adhesion requirements after aging. 4.4.4 Accelerated Weathering 4.4.4.1 Method: Interior cycle per CEMS GT-31.

Surfaces that are not normally visible shall be indicated on the print and shall meet a mutually agreed level of surface quality and be so stated in the part control plan. The exposed foam surface shall be free of voids or imperfections detrimenta
25、l to strength, fit, function, or service life. 5.2 Qualification Materials submitted for approval to this specification shall include the following: 5.2.1 A detailed, signed test report documenting testing to this specification per TMS-9543. 5.2.2 The complete procedure used for preparing and curing
26、 materials for test, especially surface preparation (when appropriate) and condition of the test materials. 5.2.3 A complete description, including engineering prints and pictures of any non-standard test fixtures used. 5.2.4 Adhesive, substrate and any chemicals used for bonding where appropriate.
27、5.3 Submission The material test report shall be submitted to: Manager of Materials Engineering NAVISTAR, Inc. PO Box 1109 Fort Wayne, IN 46801 5.4 Approval A report from Navistar will be issued approving new materials to this specification. Formal approval is not granted until this report has been
