Product Information

It is because that hygrothermal conditioning treatments reduce the residual stress [ 15, 19, 25], which is mainly caused by the “supporting mold. The temperature of the injection molding machine from the hopper to the nozzle is divided into three segments; more precisely, the ranges of temperatures of the first, second, and third segment are 275–285, 260–275, and 250–265°C, respectively, while the injection pressure is 85 MPa, the dwell time is 3 s, and the injection speed is 50 mm/s. The dimensional accuracies and mechanical properties of fiber-reinforced polyamide products are influenced by moisture and temperature because PA66 has a high polarity and tends to absorb water molecules to form hydrogen bonds. Our special glass fiber reinforced PA 66 GF25, dry impact resistant mixture is ideal for the production of slimline structural and reinforcement profiles while maintaining required Uf values.

The results showed that the Mo’s model can successfully describe the non-isothermal crystallization kinetics of PA66-GF25 FR (RP) untreated and treated by three different post-treatment routes, while the other two models are not applicable.

Figure 7 shows that the peripheral dimensional accuracy of the undried parts is also obviously higher than that of the re-dried ones. To improve the dimensional accuracy of the central circular hole, a linear shrinkage compensation is necessary. Injection moulding of long glass fibers reinforced polyamide 66: processing conditions/microstructure/flexural properties relationship.

Performing measurements using a micrometer showed that the dimensional accuracies were improved after the three treatment routes; however, there exist some nonnegligible differences between the accuracies obtained with the three routes. Influence of the injection molding process on the mechanical properties of (PA6/GF/MMT) nanocomposite. A study of the mechanical behaviour of a glass fibre reinforced polyamide 6,6: Experimental investigation.All these properties make this material suitable for use in parts which are exposed to high static loads over long periods in high temperature conditions. Users should be aware of PA66 propensity to absorb moisture which could affect dimensional stability. Non-isothermal crystallization of polyamide 6 matrix in all-polyamide composites: crystallization kinetic, melting behavior, and crystal morphology. Glass fiber-reinforced polyamide 66 composite with red phosphorus flame retardant (PA66-GF FR (RP)) has excellent strength and flame retardant properties, and is widely used in electrical engineering. Effect of hygrothermal ageing on morphology and indentation modulus of injection moulded nylon 6/organoclay nanocomposites.

Influence of fibers length and compatibilizer on mechanical properties of long glass fibers reinforced polyamide 66. It has been observed that RP has few effects on the mechanical properties and dimensional stability of polyamide composites [ 6, 7]. AKRO®, AKROMID®, AKROLEN®, AKROLOY®, AKROTEK®, ICX® and PRECITE® are registered trademarks of the Feddersen Group. 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.The dimensional accuracies obtained by route II are higher than route III for both the undried and dried parts. In this article, three different treatment routes were applied and analyzed after injection molding to study the roles of boiling water bath and re-drying in improving the dimensional accuracies and mechanical properties of a plate that was made of PA66-GF25 FR (RP) by performing size measurements, mechanical property tests, and micro-morphology comparisons. In addition, by using the preferred route, re-drying can further improve the tensile, bending, and even impact strength. In some studies [ 19, 25], some mechanical properties of the PA66 or PA6 composites were also found to be improved by hygrothermal aging for a relatively short period of time. It can also be seen that the fibers were elongated along the tensile direction, bearing most of the tensile force until the fibers break.

As the composite is injected, the pressure far away from the gate is lower than that close to the gate; thus, filling on this side is insufficient, resulting in more severe shrinkage far from the gate than close to the gate. 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. Moreover, the fibers shown in Figure 10(c) do not elongate as much as those in Figure 10(a) and (b).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. mm (the initial volume shrinkage is considered) is added into the central circular hole of the plate after demolding and cooling. For convenience, the longitudinal dimension of the product is collectively referred to as “LD,” the transverse dimension is collectively referred to as “TD,” and the diameter of the central hole is referred to as “DD.
