Carbon-fiber reinforced polymers (CFRPs) are widely applied to high-grade, precision and advanced industry fields due to its high strength-to-weight and stiffness-to-weight ratios. However, its poor through-thickness properties is becoming an issue. The objective of this study is to examine electrophoresis deposition (EPD) process of depositing halloysite nanotubes (HNTs) onto the carbon fabric surface for enhancing the through-thickness strength. The neutral HNTs were negatively charged and dispersed by adding sodium dodecyl sulfate (SDS) in aqueous solution and the CFRPs were fabricated using Vacuum-assisted Resin Transfer Molding (VaRTM). The bending strength and modulus, interlaminar shear strength, Mode I and Mode II fracture toughness were obtained according to ASTM standards. Electronic scanning microscope (SEM) were adopted to do the micromorphology observation.

Composite materials are the leading emerging materials over the past twenty years since its introduction. Among the natural composites, carbon black-halloysite nanotubes hybrid composite is one of the recent emerging sector in the composite field, because of its high strength with less density as compared to the metal matrix composite. In this research carbon black-halloysite nanotubes hybrid composites based on synthetic rubber copolymer of acrylonitrile and butadiene were prepared and tested. The carbon black loading was kept fixed at sixty per hour and halloysite nanotube loading was varied from zero to ten parts per hundred rubbers per hour. The effect of carbon black-halloysite nanotube hybrid fillers on the curing behaviour, mechanical properties and morphology of the high nitrile rubber nanocomposites were investigated. The cure characteristics showed that the scorch time and cure time increased with the halloysite nanotube loading. The maximum torque exhibited an increasing trend from zero to six per hour. The tensile properties which exhibited an increasing trend until an optimum loading of six per hour were mainly influenced by the high nitrile rubber-carbon black-halloysite nanotube interaction and the intercalation of rubber and carbon black into the tubules. X-ray diffraction test and scanning electron microscope studies were supported to the results obtained.

Metastable beta titanium alloys have been known to have numerous advantages such as cold formability, high strength, good fracture resistance, deep hardenability, and cost effectiveness. Very high strength is obtainable by precipitation of the hexagonal alpha phase in a bcc beta matrix in these alloys. Precipitation hardening in the metastable beta alloys may also result from the formation of transition phases such as omega phase. Ti-15-3 (Ti-15V- 3Cr-3Al-3Sn) has been developed recently by TIMET and USAF for low cost sheet metal applications. The purpose of the present study was to examine the aging characteristics in this alloy.The composition of the as-received material is: 14.7 V, 3.14 Cr, 3.05 Al, 2.26 Sn, and 0.145 Fe. The beta transus temperature as determined by optical metallographic method was about 770°C. Specimen coupons were prepared from a mill-annealed 1.2 mm thick sheet, and solution treated at 827°C for 2 hr in argon, then water quenched. Aging was also done in argon at temperatures ranging from 316 to 616°C for various times.

For fuel savings as well as energy and resource requirement, high strength low alloy steels (HSLA) are of particular interest to automobile industry because of the potential weight reduction which can be achieved by using thinner section of these steels to carry the same load and thus to improve the fuel mileage. Dual phase treatment has been utilized to obtain superior strength and ductility combinations compared to the HSLA of identical composition. Recently, cooling rate following heat treatment was found to be important to the tensile properties of the dual phase steels. In this paper, we report the results of the investigation of cooling rate on the microstructures and mechanical properties of several vanadium HSLA steels.The steels with composition (in weight percent) listed below were supplied by China Steel Corporation: 1. low V steel (0.11C, 0.65Si, 1.63Mn, 0.015P, 0.008S, 0.084Aℓ, 0.004V), 2. 0.059V steel (0.13C, 0.62S1, 1.59Mn, 0.012P, 0.008S, 0.065Aℓ, 0.059V), 3. 0.10V steel (0.11C, 0.58Si, 1.58Mn, 0.017P, 0.008S, 0.068Aℓ, 0.10V).
