PROCESSING PROPERTIES AND IN-SITU REINFORCEMENT OF PEs/TLCP BLENOS

The rheology,the miscibility of TLCP and PES and the in-situ reinforcement of blends with injection moulding and twin screw blending extrusion drawing are studied. Results show that the viscosity of blends is lower than that of TLCP and PES,and flat the processing properties can be improved by adding TLCP. TLCP and PES in blends are almost immiscible. The viscosity of PES and its blends is so high that it is difficult to inject,and they are fit for blending extrusion drawing process with twin screw extruder. As the TLCP in blends increases the viscosity if blends decreases,but the tensile strength and the brittleness increase. With the increasing of drawing ratio,the tensile strength of composite fibres is enhanced greatly and good in-situ reinforcement can be obtained.
