TLCP hybrids show that the clay particles are better dispersed in the matrix TLCP at
low clay contents than at high clay contents. Higher clay loadings are expected to
result in increased agglomeration of some portion of the clay within the TLCP
matrix. EHBT hybrids of different C25A contents were extruded with a draw ratio
of 1 from a capillary rheometer to investigate their mechanical properties. The
ultimate strength and initial modulus of the hybrids increased with increasing
