REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements Ford Production Materials (WSS-M99P1111-A). 3.1.1 All requirements of this specification, identified by symbol (s), shall be

4、met with data representing 3 sigma values. 3.2 SISAL FIBER The sisal fiber length must be at least 3.0 mm. The material must be dried for 5 h at 90 - 95 C minimum in a mechanical convection oven. The fiber humidity before the extrusion of the polypropylene compound must be less than 3%. 3.2.1 Drying

5、 Process To achieve good results at the drying process (3%), we recommend: 1) Forced Air Circulation oven with dry air line (The distances between the trays at the oven must be 5cm or more. The maximum height allowed per tray is 5cm. To improve the efficiency of drying process is recommendable some
