Polyethylene (PE) is an important polymeric material which is widely used in civil engineering. Recently, engineered cementitious composites (ECCs) have adopted PE fibers in structural repairing. ECC with polyethylene fibers (PE-ECC) has excellent tensile properties, ductility, strain-hardening behavior, thermal performance and durability. In this paper, a systematic review of the cementitious composites with PE fibers is summarized to facilitate the application of PE-ECC. The influence of PE fibers on the properties of ECC, such as compressive strength, flexural behavior, shear properties, impact resistance and tensile properties, is presented. Meanwhile, the properties of PE-ECC repaired structures, such as beams, walls and columns, are described. Further, the self-repairing properties of PE-ECC are presented. Finally, some suggestions for future research are provided in order to apply PE-ECC to practical repairing cases. The review exhibits that PE-ECC is of notable significance to the repairing of structures and clarifies its application scope.

“…The HDPE and UHMWPE specimens were subjected to dynamic compressive mechanical property test at temperatures of −40 °C, −20 °C, 25 °C, 50 °C, 70 °C, 90 °C, and 120 °C. The temperatures of the specimens and the bar sections contacting the specimens were preserved for 5 min before each test to ensure that the specimen temperature and test temperature were consistent [ 8 ]. In the test, an empty bar test was carried out at various temperatures.…”

“…To investigate the dynamic compressive mechanical properties of the two materials at different temperatures, a liquid nitrogen furnace and a heating furnace were used to cool and heat the specimens, respectively. The HDPE and UHMWPE specimens were subjected to dynamic compressive mechanical property test at temperatures of −40 • C, −20 • C, 25 • C, 50 • C, 70 • C, 90 • C, and 120 • C. The temperatures of the specimens and the bar sections contacting the specimens were preserved for 5 min before each test to ensure that the specimen temperature and test temperature were consistent [8].

“…Polyethylene is a high-quality material with favourable chemical stability, impact resistance, and low-temperature resistance. It has been widely used in various fields, such as firearm technology, transportation, medical instrumentation, biocomposites, construction, and retrofit [ 6 , 7 , 8 ]. Daniel et al [ 9 ] used two different series of bio-based polyethylene (BioPE) to manufacture biocomposites, supplemented by thermomechanical pulp (TMP) fibers, and the results showed that BioPE’s 3D printing has been improved by adding 10% and 20% of TMP to the composition fiber.…”

The mechanical properties of polyethylene (PE) materials are greatly influenced by their molecular structures, environmental temperature, and strain rate. In this study, static and dynamic compression tests were performed on two semicrystalline PE materials—ultrahigh molecular weight polyethylene (UHMWPE) and high-density polyethylene (HDPE). The stress–strain curves of HDPE and UHMWPE under uniaxial compression at temperatures of −40–120 °C and strain rates of 0.001–5500 s−1 were obtained. The research findings suggest that both the UHMWPE and HDPE showed significant strain rate-strengthening effect and temperature-softening effect. In particular, HDPE exhibited better compression resistance and high-temperature resistance. The relationships between the yield stress and temperature and between the yield stress and strain rate for both materials were fitted, and the Cowper–Symonds constitutive model was built while considering the temperature effect. The parameters of the constitutive model were obtained and input into LS-DYNA software to simulate the dynamic compression process of HDPE. The simulation result was consistent with the test result, validating the accuracy of the constitutive parameters.

“…In the global industry, ultra-high molecular weight polyethylene (UHMWPE) fibers are the leading high-performance fibers and widely used in armor applications. These fibers show great resistance against impact or blast loads being a promising alternative for aramids in armor products [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ]. Czechowski et al [ 8 ] compared aramid with UHMWPE (Dyneema) composites conducting a rigorously study including tensile, hardness, bending and delamination test.…”

The aim of the present work is to provide a methodology to evaluate the influence of stacking sequence on the ballistic performance of ultra-high molecular weight polyethylene (UHMWPE) protections. The proposed methodology is based on the combination of experimental tests, numerical modelling, and Artificial Neural Networks (ANN). High-velocity impact experimental tests were conducted to validate the numerical model. The validated Finite Element Method (FEM) model was used to provide data to train and to validate the ANN. Finally, the ANN was used to find the best stacking sequence combining layers of three UHMWPE materials with different qualities. The results showed that the three UHMWPE materials can be properly combined to provide a solution with a better ballistic performance than using only the material with highest quality. These results imply that costs can be reduced increasing the ballistic limit of the UHMWPE protections. When the weight ratios of the three materials remain constant, the optimal results occur when the highest-performance material is placed in the back face. Furthermore, ANN simulation showed that the optimal results occur when the weight ratio of the highest-performance material is 79.2%.
