“…We first determine the dependence of DNA topology and microtubule concentration on linear viscoelasticity which we extract from thermal oscillations of embedded trapped microspheres (Methods, Figs 1,2). As shown in Figure 2a, the elastic modulus G'(ω) of R-MT composites increases monotonically with increasing MT concentrations over the entire frequency range, indicating increased elasticity.…”

“…Polymer composites, multi-component materials consisting of a continuous polymer matrix reinforced with fillers, [1][2][3][4][5] are of wide-spread importance in the natural and commercial world, with applications ranging from aerospace engineering to drug delivery [6][7][8][9][10][11][12] . Commercial interest stems from the fact that composites often exhibit emergent rheological and structural properties that are superior to those of the constituent materials 2,4,5,[13][14][15][16][17][18][19][20] . For example, composites of stiff and flexible polymers can exhibit enhanced strength, and stiffness compared to single-component systems while concomitantly reducing weight [21][22][23][24] .…”

Polymer composites are ubiquitous in biology and industry alike, owing to their emergent desirable mechanical properties not attainable in single-species systems. At the same time, polymer topology has been shown to play a key role in tuning the rheology of polymeric fluids. However, how topology impacts the rheology of composites remains poorly understood. Here, we create composites of rigid rods (microtubules) polymerized within entangled solutions of flexible linear and ring polymers (DNA). We couple linear and nonlinear optical tweezers microrheology with confocal microscopy and scaled particle theory to show that composites of linear DNA and microtubules exhibit a strongly non-monotonic dependence of elasticity and stiffness on microtubule concentration due to depletion-driven polymerization and flocculation of microtubules. In contrast, composites of ring DNA and microtubules show a much more modest monotonic increase in elastic strength with microtubule concentration, which we demonstrate arises from the increased ability of rings to mix with microtubules.

“…90% of the market of reinforced plastic composites [ 10 ]. As a filler, silica (SiO 2 ) is often used either in its pure state or in various combinations with metal oxides to improve various properties of the composite among which are the mechanical properties, as well as abrasion resistance [ 11 ]. Among silicon dioxide-based commercially available fillers for polymer composites, the following can be distinguished: glass beads produced by the melting and molding of fine glass powder to obtain spherical particles; foundry sand with spherical particles fabricated out of bauxite by melting in electric-arc furnace and subsequent spraying and cooling; crystalline silica prepared using chemical purification and mechanical fragmentation of the natural quartz; and amorphous fused silica produced by melting crystalline silica, its re-solidification, and subsequent crushing and pulverizing [ 12 ].…”

The paper presents the results of investigations on the glass fiber reinforced composite for the floor panels with quartz powder additions of different percentages in terms of wear resistance, friction coefficient, hardness, and strength. The wear resistance was assessed using the specific wear work parameter determined by the novel tribotester with friction band. It was found that an increase in quartz powder addition to the tested polymer composite does not enhance its mechanical increasingly properties. From the wear tests it can be concluded that only the composite with four layers of glass fibers and 6 wt.% of the quartz powder exhibited improvement of the wear resistance, but its shear strength was lower than that of the two layer specimens with similar powder proportions. On the other hand, the highest friction coefficient’s, which is microhardness HV05, shear strength and impact strength were attained for the composite with two layers of glass fibers and 3 wt.% of the quartz powder. Among four layer samples, very close results were obtained for the samples with 10% of powder and insignificantly lower strength were observed for the samples with no powder added. The results revealed that there is no clear trend for the effect of silica filler percentage on the composite performance, which indicates the need for individual purpose-dependent decision making in the design of the glass fiber reinforced composites with quartz powder filler.

“…Polymer composite materials (PCM) have been the subject of intensive research over the past two decades [1]. The peculiarity of this type of material is the presence in their composition of inorganic fillers of very small size, which, when interacting with a polymer matrix, improve its physical properties.…”

Polymeric materials that contain inorganic fillers demonstrate a unique set of physical properties due to the combination of matrix elasticity and filler strength. This paper reports determining the effect of dispersed aluminum particles on the properties of polyvinylidene fluoride-based materials. This study result is the fabrication of a series of composite materials using a piston extruder. Their functional characteristics have been explored using the methods of thermophysical and mechanical analysis, dilatometry, and acoustic spectroscopy. It was established that the introduction of dispersed aluminum particles leads to the loosening of the matrix, which may indicate the transition of macro macromolecules from the crystalline phase to the boundary layer around the filler. This feature of structure formation and the uniform distribution of filler particles ensured the improvement of the functional characteristics of the materials obtained. It has been shown that with an increase in the content of filler in the system to 5 % the thermal conductivity increases from 0.17 W/(m·K) to 1.55 W/(m·K). The introduction of the filler leads to an improvement in the heat resistance of the materials obtained, by 17 K. The increase in both melting point and destructiveness is explained by the formation of a more perfect polymer structure with a higher degree of crystallinity. An increase in the speed of ultrasound propagation was identified, by 67 %, as well as in the tensile strength, by 36 %, in the materials obtained, which can be explained by contributions from the filler, which has greater sound conductivity and mechanical strength than the polymer matrix. Such systems show the reinforcing effect of aluminum particles on the polymer matrix, so they could be used as structural materials with improved functional characteristics
