Synthesis, processing and characterization of impact hardening gel (IHG) reinforced Kevlar fabric composites

Novel shear thickening gel/high‐performance fiber reinforced flexible composites: Multi‐velocity impact and functional properties

“…The reinforcement of STG/high-performance fiber flexible composites is typically made of high-performance fiber, particularly Kevlar, carbon, aramid, and UHMWPE fiber. [11] They are extensively used in multi-velocity impact resistance based on their high tensile strength and modulus characteristics. [38] Reinforcement structures are generally divided into two categories: two-dimensional fabric and threedimensional fabric.…”

“…STG is obtained by cooling the final product at room temperature. [11,13,15,34,35] Excessive BA or silicone oil will diminish the amount of B O crosslinking bonds (Figure 3C). The relative shear thickening effect rises and then decreases when the weight percentage of pyroboric acid to PDMS is 0-0.6.…”

“…[8][9][10] However, the low stability caused by the weak STF and fiber interaction substantially impedes development. [11,12] STG is a novel solid shear thickening material based on STF. STG/high-performance fiber flexible composites outperform STF/highperformance fiber flexible composites regarding stability.…”

Structure and impact properties of a thermoplastic elastomer/silly putty blend

“…8,9 Recently, a new generation of impact-resistant materials has adopted polyborosiloxane (PBS) as an active component to dissipate impact energy. [10][11][12][13][14][15][16][17][18][19] PBS is a kind of supramolecular polymer with boron-oxygen dynamic dative bonds (Si-O:B), [20][21][22] which endow PBS with unique viscoelasticity. 20 Under normal static conditions, PBS is soft, but when it is impacted, it hardens to increase the force area and dissipate a lot of energy.…”

“…23 So, PBS has become a good choice for shock resistance, and is currently widely used in various damping components, personal protection, etc. [10][11][12][13][14][15][16][17][18][19] However, as pure PBS deforms easily under gravity, it cannot hold its shape at room temperature, and thus PBS is generally only used as one part of composites to form impact-resistant materials. 19 Concerning fundamental research on impact-resistant materials based on PBS, there have been fabric composites made by PBS and fabrics (such as Kevlar fabrics), 10,12,14,17 polymer foams with PBS, [24][25][26] thermoset elastomers with PBS [27][28][29][30] and thermoplastic elastomers with PBS.…”
