Accordingly, it is an object of the present invention to provide new composite materials with
high mechani cal strengths and excellent high-temperature character istics, and a process
for manufacturing same. It is another object of the present invention to pro vide new
composite materials of narrow molecular weight distribution, and a process for
manufacturing

Composite material with high mechanical Strength and excellent high-temperature
characteristics comprising a polymer matrix containing polyamide and layers of a Silicate
uniformly dispersed in the order of molecules in the polymer matrix, each of Said Silicate
layers being 7 to 12 A thick and the interlayer distance being at least 20 A; and a proceSS
for manufacturing Such composite material.
