Ultra-High-Molecular-Weight-Polyethylene

The tensile modulus and tensile strength of the UHMWPE/HDPE were increased with the incorporation of CNF, while a decrease appeared at a higher content. Storage Modulus-25.5% Loss of modulus-68%: Flexural strength-79.8%

The Structure and Mechanical Properties of the

It was shown that the values of storage modulus for the UHMWPE/GNP/PANI films were increased in comparison with the virgin UHMWPE film and the highest value for the UHMWPE/GNP/PANI film was obtained for 2 wt % GNP/PANI.

Ultra-High-Molecular-Weight-Polyethylene

Ultra-High Molecular Weight Polyethylene (UHMWPE) is used in biomedical applications due to its high wear-resistance, ductility, and biocompatibility. A great deal of research in recent decades has focused on

Characterization of Physical, Chemical, and Mechanical Properties of UHMWPE

Young''s modulus E, the yield stress σ Y, ultimate tensile stress σ UTS, and elongation at failure %ɛ are all determined from this curve as shown in Figure 29.20 B. Note

Effect of PEW and CS on the Thermal,

Modified ultra-high-molecular-weight polyethylene (UHMWPE) with calcium stearate (CS) and polyethylene wax (PEW) is a feasible method to improve the fluidity of materials because of the tense entanglement network

Strategies for enhancing the processability of

To assess this further, the polymers were subjected to a DSC annealing protocol, 28 and time-domain melt rheometry (Fig. 2 and S18–S22†). 57,58 The increase in storage modulus (G ′) as a function of time – consistent

Ultra-High-Molecular-Weight-Polyethylene

Among these, polyethylene is suitable due to the better miscibility and structural similarity. Khashoggi blended UHMWPE with HDPE and found that the viscosity, storage modulus, and loss modulus were decreased by increasing HDPE

6 FAQs about [Uhmwpe storage modulus]

What is the storage modulus of UHMWPE (UHMWPE) at a high temperature?

At temperature higher than 130 °C, the storage modulus tends to zero as a result of polymer melting. The curves of the loss modulus reach maximum for all porous UHMWPE samples in the temperature range of 40–60 °C, Fig. 4 e.

How much does UHMWPE increase tensile strength and flexural modulus?

The tensile strength, flexural strength, and flexural modulus increase by 13.8%, 25.7%, and 32.5%, respectively. The UHMWPE is the continuous phase when the proportion of HDPE is low.

Does HDPE reduce storage modulus?

The molecular weight of HDPE is relatively lower than UHMWPE, resulting in the drop of the elasticity of the blends with the increasing proportion of HDPE. Thus, the addition of HDPE reduces the storage modulus.

How does peg affect the mechanical properties of UHMWPE/peg blends?

In addition, the apparent shear viscosity, storage modulus, loss modulus and the complex viscosity decrease with the increasing amount of PEG. However, the mechanical properties of UHMWPE/PEG blends decrease as the PEG content increase.

What is the best ratio of UHMWPE & HDPE?

The incorporation of HDPE can further improve the processability of the UHMWPE/PEG blends and reduce its apparent shear viscosity, storage modulus, loss modulus and complex viscosity. Mechanical properties test reveals that the best ratio of UHMWPE/HDPE is 60/40.

What is the tangent of UHMWPE?

The tangent δ of initial porous UHMWPE decreases to 0.07, while hybrid porous structures possess a slightly higher damping ability (approx. 0.1) at 100 Hz loading frequency. Fig. 4 d,e,f show the temperature dependence of the storage modulus, loss modulus, and tangent δ.
