The invention also provides an interlayer for a laminated glass which provides for good deaeration without a risk for premature marginal sealing even if the temperature at initiation of deaeration at preliminary contact bonding is not critically controlled and which does not require raising of temperature for achieving a marginal seal of the glass-interlayer assembly, and a laminated glass containing said interlayer.

A composite material having a preferably rigid preformed ceramic fiber matrix at least partially impregnated with an aerogel and forming a multi-layered material. The matrix is impregnated with an aerogel material which forms a layer having a total thickness r where r is less than t or equal to t, where t is the thickness of the matrix, thus forming a single or multilayered composite material. The material may be formed with numerous layers s1, s2, S3, . . . snn where r=SIGMAsn and r is less than or equal to t. Thus, a multi-layered material is formed. Alternatively, the aerogel/fiber matrix composite has channels devoid of aerogel.
