“…An area of developing interest is the ultrasonic assembly of composite materials [12], [13], [14], [15], [16], [17], [18], [19] and the related areas of metamaterial manufacture [20], [21]. In addition to producing a particular distribution of particles the manufacture of a composite material requires the additional step of curing the host materials to create a solid.…”

“…For example, the removal of ultrasonically assembled composite samples from inside the devices manipulation cavity is often achieved only with great difficulty, due to chemical bonding of the polymer to its surroundings. Furthermore, previous particle manipulation devices typically operate at a limited number of specific resonant frequencies, thus limiting the number of predetermined patterns that can be formed by a single device [12], [13], [14], [15], [16], [20], [17], [18], [19], [21].…”

“…The ultrasonic transducer was powered to propagate surface waves through the plate and thus emit a sound wave into the adjacent fluid in the microfluidic system. 18,23,24 A CW sinusoidal signal from a function generator (NF 1942) was amplified using a 55 dB power amplifier (ENI 1140LA) and the input power was measured using a power meter (Towa TAW60A). The combined sonochemiluminescent light emissions from the solutions in the 1D and both 3D spaces was detected with a photomultiplier tube (Hamamatsu R928) and, in addition, light emitted solely from the 1D space was measured by temporarily shielding the 3D space emission with aluminum foil.…”

This work examined the effects of dissolved gas degree of saturation (DOS) on sonochemical reaction yields in both a one-dimensional (1D) microspace and a three-dimensional (3D) millimeter-sized space. The extent of each reaction was monitored by measuring sonochemiluminescence (SCL) intensity at 213 kHz. The results demonstrated that, at relatively low levels of power density, selecting a solution DOS in the supersaturation range at atmospheric pressure resulted in higher yields per unit volume in the 1D space compared to that obtained from the 3D space. This effect is attributed to a decrease in the cavitation threshold of the 1D reaction system since, at low power density, the 1D space represents a more homogeneous reaction volume. Comparing the highest SCL intensity levels obtained from the 3D and 1D reactions shows that enhancing the reaction yield in the 1D space requires higher DOS values than are required to generate elevated yields in the 3D space. The 3D space contains a greater concentration of bubbles than the 1D space, but many of these are ineffective at promoting the reaction. Thus, reactions in the 3D environment require not only the application of higher power density levels but also a lower DOS, so as to allow the bubbles to undergo the violent pulsations necessary to facilitate the sonochemical reaction.

“…Structures with high and low coefficient of thermal expansion (CTE) provide zero and tunable thermal expansion, lattices with two materials of contrasting linear coefficients give rise to a negative Poisson ratio can be used to improve thermal stability, reduce weight and extend the life of many components and structures [148]. Other composites produced with aligned reinforcement for various applications reported non-AM approaches [149][150][151][152][153]. It is noticeable that most research on field-assisted additive manufacturing processes is solely focused on achieving alignment of reinforcement in the X-Y plane either for aesthetics or to overcome anisotropy.…”

Composite Reinforcement Architectures: A Review of Field-Assisted Additive Manufacturing for Polymers

et al. 2019

The demand for additively manufactured polymer composites with increased specific properties and functional microstructure has drastically increased over the past decade. The ability to manufacture complex designs that can maximize strength while reducing weight in an automated fashion has made 3D-printed composites a popular research target in the field of engineering. However, a significant amount of understanding and basic research is still necessary to decode the fundamental process mechanisms of combining enhanced functionality and additively manufactured composites. In this review, external field-assisted additive manufacturing techniques for polymer composites are discussed with respect to (1) self-assembly into complex microstructures, (2) control of fiber orientation for improved interlayer mechanical properties, and (3) incorporation of multi-functionalities such as electrical conductivity, self-healing, sensing, and other functional capabilities. A comparison between reinforcement shapes and the type of external field used to achieve mechanical property improvements in printed composites is addressed. Research has shown the use of such materials in the production of parts exhibiting high strength-to-weight ratio for use in aerospace and automotive fields, sensors for monitoring stress and conducting electricity, and the production of flexible batteries.
