Product Information

The addition of a “supporting mold” can inhibit the continuous linear shrinkage of the composite to a certain extent, improving the dimensional accuracies of the product; however, at the same time, it will increase the residual internal stress inside the products and lead to a serious decline in the mechanical properties.

Offering excellent heat resistance, polyamides can be used in the toughest of conditions, for example exposure to hot and humid environments.

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 dimensional accuracies and mechanical properties of the plate meet the engineering requirements, as shown in Figure 1 and Table 2, respectively.

Furthermore, the transverse dimension of the plate decreases gradually from the gate side to the nongate side, which means that the shrinkage of the nongate end is the most obvious. 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 mentioned earlier, it can be indicated that different hygrothermal conditioning treatments can lead to different dimensional stabilities and mechanical properties [ 25], which mainly depend on the combined effects of water molecules [ 19, 22], crystallinity [ 15, 19, 25], crystal structure phase transition of polyamide [ 13, 25, 26, 27, 28], and, perhaps the most important, the interfacial bonding [ 19, 20, 21, 22] between GFs and polyamide. Figure 8 shows the tensile, bending, and impact properties of the plate treated by the three routes.

The tensile fractured surfaces of the samples treated by the three routes were coated with gold to prevent electrical charging. mm (the initial volume shrinkage is considered) is added into the central circular hole of the plate after demolding and cooling.

Our special glass fiber reinforced PA 66 GF25, dry impact resistant mixture is ideal for the production of structural and reinforcement profiles.

It is because that hygrothermal conditioning treatments reduce the residual stress [ 15, 19, 25], which is mainly caused by the “supporting mold. To further evaluate the effect of the three treatment routes on the mechanical properties of the dried plate, the tensile fracture surface morphologies of the samples were analyzed by SEM, as shown in Figure 10. Users should be aware of PA66 propensity to absorb moisture which could affect dimensional stability. 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)).
