Novel antistatic glass fiber reinforced heat‐resistant PA10T composites with excellent processing properties and thermal stability

Abstract

In this work, the antistatic effect of antistatic agent (AA) on semi-aromatic poly (decamethylene terephthalamide) (PA10T) with 30 wt.% glass fiber (GF) was investigated. The PA10T/AGF antistatic composites with excellent thermal characteristics, balanced toughness, and notched impact strength were prepared through one-step melt blending, and added the AA and GF to the PA10T matrix.Meanwhile, the structure, morphology, thermal properties, and mechanical properties were examined in detail by FT-IR, SEM, TGA, DSC, and tensile and impulse testing. The results showed that the antistatic GF dispersed well in the PA10T matrix and interacted well with the PA10T matrix. The antistatic properties increased with the increase of AA content, and AA/GF-5 composites had the best antistatic effect when AA content was 25 wt.%. However, with the increase of AA content, the melt temperature of PA10T/AGF composites decreased, while the machining performance and thermal stability of PA10T/ AGF composites increased. The composites' tensile strength and breaking elongation followed a rising and falling pattern with increasing AA concentration. Notwithstanding, the notched impact strength of PA10T/AGF composites decreased and then increased. Therefore, this work provides us with a deep understanding of the antistatic effect of AA on polymers.

Improved Strength and Heat Distortion Temperature of Emi-Aromatic Polyamide 10T-co-1012 (PA10T/1012)/GO Composites via In Situ Polymerization

“…Therefore, the most common modification method for semi-aromatic polyamide modification at present is melt blending. Zhu et al [ 27 ] added 20 wt% of antistatic agent (AA) and 30 wt% of glass fiber (GF) to PA10T matrix by one-step melt blending. They found that the tensile strength of PA10T/AGF composites increased from 66.35 to 88.55 MPa, the electrical resistance decreased from 900 MΩ to 100 MΩ, and the antistatic properties were greatly improved.…”
