The raw materials were weighed according to the formulations of examples 1-3, and the following steps were independently completed:
preparation: mixing the weighed raw materials, putting the mixture into a screw extruder for mixing, and extruding a sheet, wherein the temperature of the screw extruder is set to be 150-165 ℃, the width of the sheet is 1.5-6 cm, and the thickness of the sheet is 3 mm;
test material draw ratio (i.e., the ratio of the drawn length to the original length at break, drawn in the lengthwise direction) for the test sheet is reported in Table 1 below;
drawing, as shown in fig. 1, preparing a drawing device 1, wherein the drawing device 1 is provided with an th pressing roller 11, a second pressing roller 12 and a curved cushion block 13, the rotation speed of the th pressing roller 11 is set to be 5RPM, the rotation speed of the second pressing roller 12 is set to be 105RPM, the temperature of the curved cushion block 13 is set to be 100 ℃, a sheet material passes through the drawing device 1, the sheet material is drawn along the length direction thereof because the rotation speed of the second pressing roller 12 is greater than that of the th pressing roller 11, the structure of the sheet material 2 before drawing and the sheet material 3 after drawing is shown in fig. 2, the width of the sheet material 3 after drawing is 0.8cm-3cm, and the thickness of the sheet material is 0;
weaving: as shown in fig. 3, the stretched sheet 3 is woven into a warp and weft direction to obtain a woven plate 4;
compounding, as shown in figure 4, preparing two PP sheets 5 and 3-5 woven plates 4 with the thickness of 0.1-0.25mm, superposing the PP sheets 5, 3-5 woven plates 4 and the PP sheets 5, and then placing the superposed PP sheets in hot-pressing equipment for hot pressing, wherein the hot-pressing temperature is 120-;
and (2) testing: the composite woven panel 6 was tested for impact strength and reported in table 1 below.
TABLE 1 test results
| Example 1 | Example 2 | Example 3 | |
