In magnetic abrasive finishing, the development of a multiple pole-tip system using partially heat-treated tool allows finishing regions simultaneously in capillary tubes and thus improves efficiency. To further reduce processing time required, new high-speed machine is fabricated. This paper describes equipment, which capable rotating spindle up to 30000 min-1, effects tube rotational speed on motion during experiments. Also, mechanisms are clarified.
The focus of this study is the influence voids on damage behaviour in quasi-static loading resin-infused carbon fibre-reinforced polymers. Experimental results are presented for combination with high-resolution tomographic imaging and statistical analysis (homology pores or induced cracks). Three distinct mechanisms were observed to control delamination growth presence sharp blunt voids. Delamination cracks interact supporting yarns, especially air pockets trapped resin form long, This...
In flow simulation of liquid composite molding under a flexible cover, such as vacuum infusion (VI), the accuracy can be improved by accounting for compressibility reinforcement. The has been predominately measured using universal testing machine (UTM) but discrepancies have observed between determined UTM and that in situ during VI processing. differences two are thought to due (1) hydrodynamic loading (2) precision difficulties related small displacements being measured. characterization...
Flow simulation for liquid composite molding is often performed to assist in process optimization and requires the permeability of reinforcement be characterized. For infusion under a flexible membrane, such as vacuum infusion, or part with non-uniform thickness, one must test at various levels compaction. This time consuming relies on interpolation extrapolation around few experimental measurements. To accelerate characterization, small number methodologies have been previously presented...
Liquid composite molding (LCM) is growing in importance as an alternative to traditional prepreg-autoclave methods for manufacture high-performance composites. The most significant roadblock industry’s implementation of LCM the usually higher void content compared with prepreg processing. One tool reducing levels involves optimization flow velocity, which requires models be developed describe formation at a given velocity. To help solve this problem, following research illustrates first...
Abstract Liquid composite molding (LCM) is a promising option for low‐cost manufacturing of high‐performance composites compared to traditional prepreg‐autoclave methods. Void formation may be the most significant roadblock such adaptation LCM. In this article, hypothesis that higher wettability, is, lower contact angles liquid on solids, would lead void content LCM tested. First, theory calculates energy required form bubble with varying formulated by considering interfacial differences...
Abstract The ultracentrifuge provides an easy and fast way of estimating the physical properties reservoir rock/reservoir fluid systems such as wettability information, capillary pressure relative permeability curves. has been utilized both in routine core analysis at research level. In this work, extensive experimental program was conducted for characterization from Rainbow Lake Reefs. Numerous plugs were tested characteristics. During procedure, it found that conventional use centrifuge...
Abstract Fiber-reinforced composites have potential advantages for manufacturing origami arrays. However, methods large arrays using composite materials are complex, time-consuming, and expensive. This research proposes two processes synthesizing origami-based arrays, each made fiber-reinforced requiring only a single layup. The overarching principle used in these is to selectively modify the stiffness array, thus forming both panels hinge lines of an array. feasibility produce deployable...
