    Why Reinforce Nylon? The Performance Gap<\/h2>\n

    Unfilled nylon is an excellent general-purpose engineering plastic, but its modulus (2.8-3.0 GPa) and thermal resistance (HDT 65\u00b0C at 1.82 MPa) fall short for structural and high-temperature applications. Reinforcement fillers \u2014 glass fiber and carbon fiber \u2014 close this gap dramatically.<\/p>\n

    The choice between glass fiber and carbon fiber reinforcement is one of the most consequential material decisions in precision engineering. It determines stiffness, strength, dimensional stability, weight, cost, and processing characteristics. This guide provides the complete comparison engineers need.<\/p>\n

    Cost Analysis<\/strong> (approximate, USD\/kg): | Material | Price Range | Notes | |—|—|—| | Unfilled PA66 | $3-5 | Baseline | | PA6-GF30 | $4-7 | ~40% premium | | PA66-GF30 | $4.5-8 | Most common reinforced nylon | | PA6-CF30 | $18-30 | Carbon fiber premium | | PA66-CF30 | $20-35 | Premium specialty | | Aluminum 6061 | $5-8 | Metal comparison |<\/p>\n

    Key insight<\/strong>: Carbon fiber nylon costs 4-7\u00d7 more than glass fiber nylon but provides only 20-30% higher strength and 50-70% higher stiffness. The premium is justified primarily when weight reduction, ESD properties, or reduced warpage are critical requirements.<\/p>\n

    Strength and Stiffness<\/strong>: Carbon fiber reinforced nylon outperforms glass fiber in every mechanical property, but the margin varies:<\/p>\n
