Investigation of the properties of PA6/PA610 blends and glass fiber reinforced PA6/PA610 composites

Abstract

Polyamide (PA) is the mostwidely used type of semi‐crystalline polymer among engineering plastics, with its low density and high mechanical properties. But the high moisture absorption of PA6 limits its use in some areas. Blending and the addition of reinforcement can decrease the moisture absorption value of PA6. In this research, the PA6/PA610 blends and glass fiber (GF) reinforced PA6/PA610 composites were fabricated, and the features of these blends‐composites were examined. The blends and composites were produced by using extrusion and injection molding methods and characterized by water absorption (WA) test, tensile test, scanning electron microscopy (SEM), dynamic mechanical analysis (DMA), thermogravimetric analysis, and differential scanning calorimetry (DSC). The loading rates of GF were used as 10–20‐ 30–40 wt%. According to the tensile test consequences, the highest increase in the tensile strength for the composites was observed at 30% GF ratio. DMA results demonstrated an increase in loss modulus and storage with the increasing fiber amount. It is observed that the WA value of neat PA6 was diminished by blending with PA610 and adding an increasing amount of GF.

A comprehensive dimensional analysis of waste‐derived reinforcements in interface interactions with semi‐bio‐based PA6,10 composites

“…16 In a recent study, Artykbaeva et al used a PA6-PA6,10 blend matrix with 40% GF reinforcement to improve the tensile modulus and strength by 5 times and 57%, respectively. 17 Similarly, Nikiforov et al investigated the effect of several fiber reinforcements in PA10,10 and reported that, at 40% GF loading, tensile modulus and yield strength improved by 455% and 184%, respectively. 18 In another study, Quiles-Carrillo et al reported the effects of silane treatment on the wastederived slate fiber-reinforced PA10,10 composite parts and concluded that glycidyl-silane treated fibers improved tensile modulus by 241% while the tensile strength improved by 96%.…”

Synergistic effect of the glass bead and continuous glass fibers on the low‐velocity impact resistance of nylon 6 matrix composites

“…PA6 is widely used as a matrix for composite materials because it is a semi-crystalline thermoplastic, which has high hardness, impact resistance, excellent chemical properties, and heat resistance. [30][31][32] In addition, glass fiber (GF) and glass beads (GBs) are well-suitable as reinforced materials for composite materials because they are low density, excellent chemical and thermal stability. 33 In this paper, the synergistic reinforcement effect between particles and fibers is demonstrated by continuous GF with GBs co-reinforced nylon 6 (GB-GF/PA6) composites.…”

Significant enhancement of mechanical properties for glass fiber fabric‐reinforced polyamide 6 composites by improving interfacial bonding

“…Fiber-reinforced polymer (FRP) composites have been widely used in various fields such as transportation, energy infrastructure, and wind power generation due to their excellent specific strength and stiffness. [1][2][3][4][5] Fiber fabrics, characterized by their bidirectional structure, provide dual support for polymer matrices and exhibit excellent mechanical properties compared to unidirectional fibers. 6 The main focus of fiber-reinforced composites is to achieve good interfacial bonding, as it plays a crucial role in determining the mechanical properties of composite materials.…”
