For aerospace structural components, material selection demands an exceptional balance of specific strength, fatigue resistance, and dimensional stability across wide temperature swings. Our PEEK rod for aerospace structural parts is engineered from high-purity polyetheretherketone resin and is routinely specified for brackets, bushings, clamp blocks, and sensor housings in airframe and engine subassemblies. As a natural PEEK rod manufacturer, we control polymerization and extrusion parameters to keep crystallinity and residual stress within narrow aerospace tolerances. The same production discipline supports our virgin PEEK round bar stock, which offers the traceable purity needed for flight-critical hardware. For assemblies exposed to thermal cycling or electrical isolation requirements, our PEEK rod high temperature insulation grades provide stable dielectric performance above 260°C. Although this series is optimized for structural use, the same base polymer and machining guidelines extend to our natural PEEK rod for medical implant materials, reflecting the resin’s broad qualification footprint. This cross-industry validation gives aerospace buyers additional confidence in lot-to-lot consistency.
The PEEK rod for aerospace structural parts is supplied in diameters from 6 mm to 200 mm, with standard lengths of 1000 mm or 3000 mm and custom cut lengths available. The base resin is unfilled virgin PEEK unless otherwise specified; carbon-fiber-reinforced and glass-fiber-reinforced variants are available for parts requiring higher stiffness or lower thermal expansion. Each rod is extruded under controlled cooling to minimize internal voids, then centerless ground or machined to meet h7/h8 diameter tolerances. A summary of key attributes follows:
| Property | Test Method | Typical Value |
|---|---|---|
| Density | ISO 1183 | 1.30–1.32 g/cm³ |
| Tensile strength at break | ISO 527 | 95–100 MPa |
| Tensile modulus | ISO 527 | 3.6–4.0 GPa |
| Flexural strength | ISO 178 | 150–170 MPa |
| Flexural modulus | ISO 178 | 4.0–4.4 GPa |
| Compressive strength | ISO 604 | 120–130 MPa |
| Izod impact strength, notched | ISO 180/A | 5–7 kJ/m² |
| Heat deflection temperature, 1.8 MPa | ISO 75 | 152–160°C |
| Continuous service temperature | UL 746B | 260°C |
| Dielectric strength, 2 mm thickness | IEC 60243 | 19–22 kV/mm |
| Surface resistivity | IEC 60093 | 1 × 10^15 Ω |
For structural part qualification, our standard PEEK rod for aerospace structural parts is accompanied by a material certificate stating batch number, resin grade, density, and tensile test results. Rods can be supplied in annealed condition with reduced residual stress for thin-wall machining or in as-extruded condition for high-volume production. Dimensional inspection is performed at 20°C against ISO 286-2 tolerances; typical straightness is better than 0.5 mm per 1000 mm. Packaging uses protective sleeves or vacuum-sealed film to prevent surface contamination before machining. Because this product is often used as a metallic replacement in weight-sensitive assemblies, our application engineers recommend verifying end-use performance against the specific service environment, including exposure to jet fuel, Skydrol, and salt spray.
