Continuous Carbon Fiber

The carbon nanotubes (CNTs) were prepared by catalytic decompose of benzene using floating transition method at 1100-1200°C. Benzene was used as carbon source and ferrocene as catalyst with thiophene. The carbon nanotubes are straight with diameter 20-50 nm, internal diameter 10-30 nm and length 50-1000 μm. The carbon nanotube and continuous carbon fiber (T300) reinforced unidirectional epoxy resin matrix composites was fabricated. The volune fraction of continuous carbon fiber (first filler) in the composites without second filler (carbon nanotube) was 60%. The mechanical properties of the composites were investigated under bending, shear, and impact loading. The flexural strength and modulus of the composites increased firstly and then decreased with the increasing of carbon nanotube contents in epoxy resin matrix. The flexural strength of the composites reached the maximum value of 1780 MPa when the weight percent of carbon nanotube in epoxy resin matrix was 3%.

Epoxy Resin Matrix

To study the dynamic compression and tensile mechanical behaviors of a bicomponent epoxy resin matrix composites, which were filled with a semi-crystalline thermoplastic Polyether-ether ketone (PAEK-C) resin, at high strain rate, the dynamic compression and tensile experiments were carried out on a modified split Hopkinson pressure bar (SHPB) and high speed material apparatus, respectively. Stress-strain curves of the epoxy resin matrix composites were obtained and analyzed. Damage mechanism under high strain rate was characterized through the scanning electron microscope (SEM) observation. Results of the dynamic compression tests indicated that, although the effects of strain rate remarkably influenced the variations in stress, the behaviors of the epoxy resin matrix played a more significant role than strain rate in the determination of the high strain rate. It was reflected through increased ductility of the samples and reduced slope of the stress-strain curves. The dynamic impact tensile tests results show that, PAEK-C fillers exhibited dramatic toughening effect. The increase of the volume fraction of PAEK-C rich phase inevitably forces the crack to overcome more tearing deformation of PAEK-C rich phase. At the same time, the enhancement of plastic capacity may also induce a larger range of cooperative deformation at the crack tip.
