Product Information

It was found that the route in which the boiling water bath is applied after the “supporting mold” is preferred to ensure the dimensional accuracies and the mechanical properties as a whole. Tensile behavior of thermoplastic composites including temperature, moisture, and hygrothermal effects. One method is to modify the mold size according to the transverse and longitudinal shrinkage ratios; the other method is to apply an external force to limit linear shrinkage after demolding. As a result, in route III, the active effect of re-drying on the impact strength, right after the “supporting mold,” cannot eliminate the negative effect of the “supporting mold” without a subsequent boiling water bath. The surface morphological images of all samples were observed by using scanning electron microscopy (SEM; Sigma 300, Germany) at an acceleration voltage of 5.

This phenomenon is caused by the different longitudinal and transverse linear shrinkage due to the anisotropy of the composite [ 11] determined by the flowing direction during the injection molding process. Figure 6(a) and (b) show the DD T of the undried and the dried parts, respectively, while Figure 6(c) and (d) show the DD L of the undried and dried parts, respectively. As shown in Figure 1, the dimensional accuracy of DD is high due to the assembly precision requirements, so the gate must be located at the region far away from the central hole (as shown in Figure 2); environments with medium voltages (approximately 10 kV) require a plate to prevent tip discharge and puncture. The dimensional accuracies obtained by route II are higher than route III for both the undried and dried parts.Furthermore, it can be seen that there is less resin on the fibers on the fracture surface treated by route II, whose tensile strength is the highest ( Figure 8(a)). Finally, through the comparison of Figure 7(a)–(c), it can be seen that the transverse dimensions of the undried parts treated by route II are all within the tolerance range, but those of the parts treated by the other two routes are not within the tolerance range. DHL Express is a division of the German logistics company Deutsche Post DHL providing international express mail services. It can also be seen that differences between the “DD T” and “DD L” for samples treated by route I without a “supporting mold” are the largest, and the values of “DD T” and “DD L” for the undried or dried parts are all out of the tolerance ranges. Influence of fibers length and compatibilizer on mechanical properties of long glass fibers reinforced polyamide 66.

Polyamide 66 (PA66) has excellent comprehensive mechanical properties and is widely used in automobiles, electronics, machinery, chemistry, and other fields.Re-drying at 110°C for 6 h can further enhance the mechanical properties of the PA66-26GF FR (RP) composite as a whole mainly because of the reduction in the internal residual stress. To improve the dimensional accuracy of the central circular hole, a linear shrinkage compensation is necessary. A plate used in a medium voltage switch, made by a 25 wt% glass fiber-reinforced polyamide 66 composite filled with flame-retardant red phosphorus (RP) (PA66-GF25 FR (RP)), was injection molded. Figure 8 shows the tensile, bending, and impact properties of the plate treated by the three routes.
