“…Therefore, PA10T is always modified for use in practical applications. Traditionally, PA10T is mainly modified by the inclusion of a high content of glass fiber or other commonly used modified fillers [ 16 , 17 ]. However, the addition of high-content of glass fiber or other filler content significantly affects the comprehensive performance of PA10T.…”

“…Over the last decade, L-FRPs have been intensely studied and are now widely used in the industry [ 5 , 6 , 7 ]. There are two commonly used types of processing technology used for glass fiber reinforced polymer composites: short glass fiber and continuous L-FRP composites [ 8 , 9 ]. L-FRP composites provide a better mechanical performance than short-fiber reinforced polymers (S-FRP).…”

In this study, fiber breaking behavior, fiber orientation, length variation, and changes in melt flow ability of long glass fiber reinforced polypropylene (L-FRP) composites under different mold cavity geometry, melt fill path, and plasticization parameters were investigated. The matrix material used was polypropylene and the reinforcement fibers were 25 mm long. An ultra-long-fiber composite injection molding machine (with a three-stage plunger and injection mechanism design) was used with different mold cavity geometry and plasticization parameters. Different screw speeds were used to explore the changes in fiber length and to provide a reference for setting fiber length and parameter combinations. Flow-length specimen molds with different specimen thickness, melt fill path, and gate design were used to observe the effect of plasticizing properties on the flow ability of the L-FRP composite materials. The experimental results showed that the use of an injection molding machine with a mechanism that reduced the amount of fiber breakage was advantageous. It was also found that an increase in screw speed increased fiber breakage, and 25 mm long fibers were shortened by an average of 50% (to 10 mm). Long fibers were more resistant to melt filling than short fibers. In addition, the thickness of the specimen and the gate design were also found to affect the filling process. The rounded angle gate and thick wall product decreased the flow resistance and assisted the flow ability and fiber distribution of the L-FRP injection molding.

“…The crystallization peaks progressively become broader and lower as the IPA concentration rises, as shown in the graph's cooling DSC curves (Figure 2). As illustrated in the DSC data (Table 1), the crystallization temperature ( T c ) of samples gradually decreased with the increase in IPA content 26 . Moreover, the second heating DSC curves in Figure 3 showed that the samples' melting temperature ( T m1 and T m2 ) gradually decreased with the copolymerization proportions of IPA increased.…”

This work synthesized the pure poly (decamethylene terephthalamide) acid (PA10T) and a series of PA10T/10I through an efficient one‐pot melt polymerization method. The structures, thermal behavior, crystallization performance, and mechanical properties of PA10T and PA10T/10I were investigated by FT‐IR, DSC, TGA, POM, XRD, and mechanics performance testing, respectively. The thermal analysis demonstrates that the melting temperature of PA10T/10I gradually decreased with the increase of isophthalic acid (IPA) copolymerization proportions. Specifically, it was observed that, the Tm1 of pure PA10T was 299.5°C, while the Tm1 of PA10T/10I‐4 with a linear downward trend was 284.7°C. And the introduction of IPA copolymerization has an obvious beneficial effect on the thermal stability of PA10T/10I (Td,5 varied from 429.5 to 434.5°C) with a wider temperature range of processing, which could potentially be applied in high‐temperature scenes. POM and XRD were used to characterize the crystallization behavior of all samples further. It was discovered that although adding IPA did not alter the crystal structure of PA10T, it dramatically reduced the size of crystalline grains and increased the number of crystal nuclei. In addition, the copolyamides possess excellent mechanical properties, and the tensile strength of PA10T/10I varied between 42.91 and 46.89 MPa, the bending strength varied between 76.69 and 85.83 MPa, and the izod impact strength varied between 25.41 and 29.82 kJ m−2. Moreover, the influence of the IPA comonomer of copolyamides PA10T/10I on melting points, thermal stability, crystallization behavior, and mechanical characteristics was investigated. This work provides a reference for preparing biobased semi‐aromatic copolyamides PA10T/10I with outstanding processing performance, excellent thermal characteristics, and adjustable mechanical properties.
