AI Technical Summary

Technical Problem

Existing insulating materials, such as syntactic foams, are inflexible and exhibit high thermal conductivity, making them unsuitable for applications requiring flexibility and low thermal conductivity.

Method used

Aerogel composite materials are manufactured by compressing and heating a gel dispersed around a reinforcing component, such as polyethylene terephthalate fibers, to create a structure with pores less than 50 nm in diameter, enhancing flexibility and reducing thermal conductivity.

Benefits of technology

The resulting aerogel composite materials exhibit improved mechanical properties, including increased flexural strength and modulus of elasticity, while maintaining low thermal conductivity and flexibility.
