Know to Different: LCF and LGF Material
The Fundamental Difference Between LGF and LCF Material
The differences between LGF and LCF primarily stem from the fibers themselves:
LGF (Long Glass Fiber)
The reinforcing fibers are glass fibers, with a high density but low cost.
The strength and rigidity are significantly enhanced, and they can replace some metal structural components.
Excellent electrical insulation, suitable for large-scale applications in industries and household appliances.
LCF (Long Carbon Fiber)
The reinforcing fibers are carbon fibers, with low density and high strength.
Excellent rigidity, fatigue resistance, and dimensional stability.
Natural conductivity, can be used for functional structural components or EMI shielding.
The cost is significantly higher than LGF.
In short: LGF focuses on cost-effectiveness, while LCF emphasizes high performance.
