Winding Tension

Based on the surface analysis of carbon fiber, an epoxy resin matrix with good wettability to carbon fibers had been developed and studied, and the influence of winding tension on the interface and mechanical properties of the composite were studied. The surface morphology of carbon fiber and the active functional groups of sizing agent were analyzed. In order to form a good interface combination, the wettability between carbon fibers and epoxy resin matrix was characterized by dynamic contact angle. The winding tension played an important role in the mechanical properties of composites. Therefore, a kind of carbon fiber reinforced composites, Naval Ordnance Laboratory (NOL) rings were fabricated using different winding tensions. Particularly, when the winding tension was 30 N, the interfacial bonding between carbon fibers and resin matrix was the most compact and firm. The tensile strength and interlaminar shear strength (ILSS) of NOL rings reached high values, 2712 MPa and 75 MPa, respectively.

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%.

The Impact

Thermoplastic and thermoset polymer composites reinforced with kenaf fiber or CaCO<sub>3</sub> have been extensively investigated. However, the study on the combination of kenaf fiber and CaCO<sub>3</sub> reinforced epoxy resin is rare. This research discussed the effect of CaCO<sub>3</sub> particle size and the ratio of kenaf to CaCO<sub>3</sub> content on the impact strength of alkali-treated kenaf/ CaCO<sub>3</sub>/epoxy resin hybrid composites. Thirty % of the hybrid kenaf fibers and CaCO<sub>3</sub> particles reinforced epoxy resin composites were fabricated by hand lay-up technique followed by cold press. Impact test of the composite specimens was conducted using a Charpy Impact test according to ASTM D 6110. The morphology of impact fracture surface was examined by scanning electron microscopy (SEM). The results showed that the impact strength of the hybrid composite increased with the decrease of CaCO<sub>3</sub> particle size, and increasing the ratio of kenaf to CaCO<sub>3</sub>. Interfacial bonding between the reinforcement (kenaf and CaCO<sub>3</sub>) and epoxy resin matrix, the uniform dispersion of kenaf and CaCO<sub>3</sub> within the epoxy resin matrix are two crucial factors influencing the impact strength of the composite.

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.
