Study on Biomechanical Properties of Quartz Fiber Reinforcd n-HA/PA66 Composites


Article Preview

Quartz Fibre/nano-Hydroxyapatite/Polyamide 66(QF/n-HA/PA66) composite was prepared by extrusion molding method. The QF is well dispersed in the nano-hydroxyapatite/polyamide 66 matrix and some interaction and new interface formed between QF and n-HA/PA66. Tensile strength, compressive strength and flexural strength of the 38wt%QF/n-HA/PA66 composite reached 81 MPa, 190 MPa and 195 MPa, which were higher than those of human cortical bone. Mechinical properties were improved with the increasing of QF content and QF well enhanced biomechanical properties of the composite. Based on the excellent biomechanical properties of composites, the long load-bearing thigh bone substitute was fabricated for tumour infected thigh bone patient.
