AEROSPACE AND DEFENSE — Frequently Asked Questions
Which grades are common in aerospace plastic parts?
Low-chlorine PPS GF40 for low-smoke/low-toxicity interiors; LCP GF30 and high-flow PPS for avionics connectors; carbon-fiber PPS (KLD30CF) to lightweight UAV structures. The core trade-off is flame and smoke density (FAR 25.853) versus weight saving.
What are the advantages of carbon-fiber PPS for drones?
Specific stiffness close to aluminum alloy with only 60% of its density, plus corrosion-free maintenance; the conductive nature of carbon fiber also enables EMI shielding. Drawbacks are anisotropy and cost — suitable for main load-bearing frames rather than thin panels.
Do defense plastic parts need extra certification?
Civilian RoHS/REACH plus relevant military-standard clauses and low smoke/toxicity testing (smoke density, toxicity index); some customers require batch traceability and sealed retained samples. Testing and sample retention can be arranged per project requirements.
Can plastics replace high-temperature metal parts?
PPS endures 200°C long-term and 260°C short-term; LCP is similar with better flow; higher temperatures need PEEK-class materials. Assess metal replacement by the temperature-load spectrum: engine hot-section parts remain metal, while surrounding brackets have large replacement potential.
