3D Printing Technique

The properties of composite materials do not depend only on the properties of raw materials but also other parameters such as volume fraction, geometry, dimension and material distribution etc. Carbon fiber reinforced polymer is one of the top choices of composite material because carbon fiber has light weigh with high tensile strength. For fiber-based composite such as carbon fiber composite, directions of carbon fiber with respect to loading direction could also affect to the strength of composite material under load. In this work, the properties of short carbon fiber-resin composite were investigated (fiber length of 0.2 mm.) with two different fiber orientations, i.e. 0 and 90 degrees to applied load. The 3D printing technique was employed in order to control carbon fiber direction and minimize material loss leading to material cost reduction. It was found that 3D printing technique could control direction of fiber in most case. However, at area with high curvature, the unexpected fiber direction was observed due to post hot process during which material flow was expected. It should also be noted that fiber path during 3D printing process may be very crucial as it could result in low strength local area due to low fiber density. This area could promote stress concentration leading to final fracture.

This paper proposes a contactless method for the identification of the electrical conductivity tensor of a carbon fiber composite materials plate using a rotating magnetic field and multi-coil eddy current sensor. This sensor consists of identical rectangular multi-coil, excited by two-phase sinusoidal current source in order to generate a rotating magnetic field and to avoid the mechanical rotation of the sensor. The fibers orientations, the longitudinal and transverse conductivities in each ply of carbon fiber composite material plate were directly determined with analysis of the impedance variation of each coil as function of its angular position. The inversion process is based on the use of artificial neural networks. The direct calculation associated with artificial neural networks makes use of 3D time-harmonic finite element method based on the A, V–A formulation.

Shape memory polymers (SMPs) have drawn wide attention of many researchers for its potential applications to shipping industry, aerospace, bionics engineering and mechanical engineering. Shape memory polymers composites (SMPCs) have ability to improve the properties and obtain attain new functions of shape memory polymers. In this paper, trans-1, 4-polyisoprene reinforced by carbon fiber is developed to improve the mechanical weakness of trans-1, 4-polyisoprene bulk. Composites with carbon fiber weight fraction of 5%, 10%, and 15% are fabricated by casting samples with an average length of 2 mm. The mechanical property of the trans-1, 4-polyisoprene reinforced by short carbon fiber is evaluated and the effects of short carbon fiber on shape memory behavior are investigated. The results indicate that there is an optimum fiber weight fraction between 5 and 15 wt% where exists an extremely low recovery ratio, re-crystallizing temperatures (Tc) and an extremely high tensile stress.
