Abstract：Polypropylene materials ,the extrusion of material directly put into a homemade dipping equipment, are extruded through the twin-screw extruder.At the same time, we put the fiberglass into the homemade dipping equipment to make the fiberglass full melt impregnation. We can get the initial continuous glass fiber reinforced polypropylene sheets. And then make the sheets by vulcanizing machine laminating to get the continuous glass fiber reinforced polypropylene sheets. The mechanical properties of the test results show that: With the increase in the amount of PP-g-MAH , the tensile strength of glass fiber sheet shows upward trend, the elongation at break did not change significantly. With the amount of compatilizer of PP-g-MAH was increased, the flexural strength shows upward trend ,when reached a certain value, the bending strength changed little. With the attend of fiber glass ,the tensile strength of polypropylene is rapidly increasing. With the increase of glass content, the tensile strength of the sheet is first increased and then decreased. Elongation at break decreased rapidly after the attend of the fiber glass .With the changes of the content of glass fiber ,the continuous sheet’s elongation at break changed little. With the accession of the glass fiber, the flexural strength significantly improved, when the glass content reaches a certain level, the bending strength has declined.Key words: melt impregnation; continuous glass; polypropylene; mechanical properties.
