The composite of carbon fiber reinforced polyethylene resin was prepared by using a twin-screw extruder. The effect of carbon fiber oxidation treating on the mechanical properties of carbon fiber reinforced polyethylene resin composite was researched. The tensile fracture failure mechanism of composite was analyzed for both untreated and air oxidation treated specimen. The experimental results indicate that when carbon fiber content is equal, the tensile strength and the elastic modulus of air oxidation-treated carbon fiber-reinforced polyethylene composite are improved than that of the untreated. When the fraction of adding carbon fiber is 3.99%, compared with the pure polyethylene resin matrix, the tensile strength, elastic modulus is increased by 13.12% and 172.91%, respectively. Compared to the untreated carbon fiber reinforced polyethylene resin composite, the tensile strength and tensile modulus is increased by 4.71% and 13.14%, respectively.

Short Carbon

Carbon fiber reinforced composites have all the ideal properties, leading to their rapid development and successful use for many applications over the last decade. In this paper, short carbon fiber reinforced Polytetrafluoroethylene (SCF/PTFE) composite were prepared with melt blending and hot-pressing techniques. The mechanical properties of this composite were investigated taking into account the combined effect of mean fiber length. Finally it can be shown that an increase in fiber length can enhance the mechanical properties of CF/PTFE composites. The fracture surface of PTFE composite was examined by SEM, to identify the topography of outside force.

The reainforcement of T700 carbon fiber was oxidized at 400°C, as-received and treated carbon fiber reinforced mini Cf/SiC matrix composites were fabricated by precursor infiltration and pyrolysis (PIP) method. The mechanical properties of the composites were determined and compared. The results showed that with the time of oxidation increased, the flexural strength of composites decreased. The flexural modulus and tensile modulus were increased by the 87.8 GPa to 92.9 GPa and 131 GPa to 150 GPa. Without oxidation pretreatment, the composites represented maximum flexural strength of 649 MPa. For 1h oxidation, the composites reached the maximum tensile strength of 821 MPa. However, carbon fiber pre-oxidation for 2h, C/SiC composites mechanical properties appeared to reduce seriously.
