“…Zeng [ 35 ] found that as the temperature increased from 80 to 120 °C, the tensile strength decreased while the interlaminar bonding strength increased. Comparing Zeng's findings with the results of this study, it is evident that the influence of temperature on in‐plane tensile strength and interlaminar bonding strengths can be modified by using different ranges of molding temperature.…”

The ultra‐high molecular weight polyethylene fiber laminates were prepared by hot pressing at temperatures ranging from 120 °C to 140 °C and pressures of 15 MPa and 25 MPa. Mechanical test results demonstrated that increasing the molding temperature improved the interlaminar shear strength, in‐plane shear strength, and bending strength of the laminates. Additionally, the in‐plane tensile properties of the laminate were influenced by both the positive effect of increased bond strength and the negative effect of reduced fiber strength. The mechanical properties of the laminate showed improvements at −50 °C but decreased at 70 °C. Low‐velocity impact tests revealed that higher molding temperature and pressure enhanced the dynamic bending stiffness and peak force while reducing the bulge in the laminate’s back. Remarkably different low‐velocity impact performance was observed in the laminate at −50° C and 70° C compared to room temperature.This article is protected by copyright. All rights reserved.

“…Cao et al [ 14 ] evaluated the effect of temperature on the ballistic performance of UHMWPE laminates, noting differences in deformation processes, failure characteristics, and penetration depths across a temperature range from −20 to 95 °C. Zeng et al [ 15 ] reported a decrease in tensile strength and an increase in interface bonding strength with rising hot-pressing temperatures. Zheng et al [ 16 ] assessed the influence of pressure and temperature on the interface bonding strength of UHMWPE fiber/styrene-butadiene-styrene resin composites through T-peel tests, finding a more pronounced effect of pressure over temperature.…”

In order to investigate the influence of a hot-pressing process on the mechanical properties of ultra-high molecular weight polyethylene (UHMWPE) fiber non-woven fabrics with stretch and in-plane shear, UHMWPE non-woven fabric samples were prepared by adjusting the temperature, time, and pressure of the hot-pressing process, and mechanical property tests were carried out so as to clarify the influence of the hot-pressing process on the mechanical properties of the samples. The results show that the hot-pressing process mainly affects the silk–glue bonding strength of the samples; in the test range, with the increase in hot-pressing temperature and time, the tensile strength and in-plane shear strength of the samples increase and then decrease, and the best mechanical properties are obtained at 130 ℃ and 7 min of hot pressing, respectively; at 130 °C, the in-plane shear strength is 39.94 MPa and the tensile strength is 595.43 MPa; at 7 min, the in-plane shear strength is 63.0 MPa and the tensile strength is 643.30 MPa; with the increase in the hot-pressing pressure, the in-plane shear strength of the samples increases and then decreases, and the highest is 52.60 MPa, achieved at 8 MPa; in the range of 5–8 MPa, the tensile strength of the specimens did not change significantly, and increased significantly at 9 MPa, reaching a maximum strength of 674.55 MPa.

“…Therefore, because the drilling process of the UHMWPE composite has not been analysed adequately for materials manufactured using hot-pressing technology, which is a common method for manufacturing protective elements against impacts [29,30], it is necessary to carry out a more in-depth study. Thus, this paper focuses on the study of the drilling process of UHMWPE composite materials manufactured by means of hot-pressing technology.…”

Ultrahigh-molecular-weight polyethylene (UHMWPE) is used in the defence industry mainly owing to its properties, such as excellent dimensional stability, excellent ballistic performance, and light weight. Although UHMWPE laminates are generally studied under impact loads, it is crucial to understand better the optimal machining conditions for assembling auxiliary structures in combat helmets or armour. This work analyses the machinability of UHMWPE laminates by drilling. The workpiece material has been manufactured through hot-pressing technology and subjected to drilling tests. High-speed steel (HSS) twist drills with two different point angles and a brad and spur drill that is 6 mm in diameter have been used for this study. Cutting forces, failure, and main damage modes are analysed, making it possible to extract relevant information for the industry. The main conclusion is that the drill with a smaller point angle has a better cutting force performance and less delamination at the exit zone (5.4 mm at a 60 m/min cutting speed and a 0.05 mm/rev feed) in the samples. This value represents a 46% improvement over the best result obtained in terms of delamination at the exit when using the tool with the larger point angle. However, the brad and spur drill revealed a post-drilling appearance with high fuzzing and delamination.
