Carbon Payback Analysis for Lightweight Mineral Fibre Composites
topic
Carbon payback analysis calculates the vehicle lifetime fuel saving CO2 reduction from mineral fibre composite lightweight structures against the higher manufacturing carbon footprint of composite versus metal alternatives, determining the breakeven mileage or flight hours at which cumulative use phase carbon savings exceed production carbon penalty, integrating vehicle use pattern, fuel carbon intensity, and primary energy mix assumptions.
Role
Provides the lifecycle carbon accounting framework for justifying higher-production-carbon mineral fibre composite material choices in transport applications where weight reduction delivers fuel savings, demonstrating that glass and carbon fibre composites in automotive, aerospace, and wind energy applications typically achieve full carbon payback within the first 10 to 20 percent of product service life.
