“…To avoid the slippage between the fabric sample and the tensile bench clamping jaws, adhesive bonding on both ends with an extension of 50 mm has been added by using epoxy resin to strengthen the part to be clamped. As the non-polar and chemical inertness of ultrahigh molecular weight polyethylene (UHMWPE) fibre surfaces inherently results in poor adhesion properties with most polymers [24][25][26][27], some little holes were made by sharp needles in both clamping fabric zone during the preparation process ( Figure 2) to increase the adhesion of the epoxy resin on the UHMWPE fibres surfaces and finally to ensure zero slippage observed in the test. Tensile tests of the 3D warp interlock fabrics were performed according to the EN ISO 13 934-1 standard.…”

As promising fibrous reinforcements in the thick composites manufacturing, 3-dimensional warp interlock fabrics (3DWIFs) are recognised more and more in the industry for their outstanding mechanical properties compared to the 2D laminates. The present work shows the influence of the fabric’s architecture on the tensile behaviour of 3DWIFs. Five kinds of 3D fabrics with different interlock structures have been designed according to the main category of binding warp yarn evolution. These five 3DWIFs, containing both binding and stuffer warp yarns and produced with the same warp and weft densities, are experimentally tested via uniaxial tensile tests. The experimental results of the different 3DWIFs have been compared to find the optimal solution based on several mechanical performances. Fabric structures have an impact on tensile properties both in the warp and weft directions. Furthermore, other influential factors, for example, the yarn crimps during the weaving process and the crimp angles of binding warp yarns in 3DWIFs, are investigated and discussed in the paper. The influence of the total crimp angles related to the binding path on the tensile properties of 3DWIFs via the inter yarns friction is summarised.

“…Although UHMWPE has many excellent performances which attract the attention of the researchers, some drawbacks restrict its wide-ranging application, such as its poor processability, weak creep resistant, and yield strength. To improve these drawbacks of UHMWPE, its blends with other polymers, [1][2][3][4][5] composites reinforced with micro-and nanoparticles [6][7][8][9][10][11][12][13][14][15][16][17][18][19] and all-polyolefin composites [20][21][22][23] have been investigated.…”

“…Tribological tests demonstrated a significant decrease in friction coefficient. Maksimkin et al 8 and Kharitonov et al 9 used a multistage process to prepare the MWCNT/UHMWPE composites and found that hot pressing and orientation stretching resulted in UHMWPE tensile strength increase from 21 to 132 MPa or by a factor of 6.3 as compared with pristine bulk UHMWPE. Fluorinated MWCNT was more efficient in reinforcement than pristine one.…”

Ultrahigh molecular weight polyethylene (UHMWPE) is an excellent property polymer, but its poor processability due to high melt viscosity limits the more wide-ranging application. To improve the processability of UHMWPE composites filled by calcium carbonate (CaCO3), a novel method is reported to modify CaCO3. PE wax coated on the surface of CaCO3 (PEW@CaCO3) can be prepared by acrylic acid–modified CaCO3 (AA-CaCO3) and PE wax. The crystallization and melting behavior of UHMWPE and its composites filled by CaCO3, AA-CaCO3, and PEW@CaCO3 was compared by differential scanning calorimetry. The processability of UHMWPE composites was characterized by torque rheometer. The effect of CaCO3, AA-CaCO3, and PEW@CaCO3 on the crystallization and processability of UHMWPE was discussed.

“…In order to obtain high performance polymer composites, it is usually necessary to add a large number of inorganic fillers to the polymer . The reinforced fillers can play the role of bridging, energy transferring and reinforcing in the polymer matrix, which makes the mechanical properties of polymer increase.…”

Tin fluoride phosphate glass (TFP‐glass) has been found to improve the rheological properties and modulus of polar polymer, but the mechanism involved is still unrevealed. In this work, a kind of poly (ethylene terephthalate) (PET)/TFP‐glass composites with low viscosity and high modulus were prepared by melt blending. In order to explore the enhancement mechanism of flowability and modulus, we investigated the structure change of PET before and after blending, the viscosity evolution of TFP‐glass during heating and the final phase morphology of PET/TFP‐glass composites. Based on intrinsic viscosity and rheological measurements, the improvement of the flowability was attributed to the decrease of molecular weight of PET and the macromolecular plasticizer effect of TFP‐glass. Non‐isothermal crystallization behaviors of the composites indicated that the crystallization properties of PET were improved due to heterogeneous nucleation effect of the TFP‐glass and the decreased molecular weight of PET. The improved crystallization of PET as well as strong interfacial interaction between PET and TFP‐glass contribute to a significant enhancement in the modulus of composites, as compared with pure PET.
