Modern ballistic helmets made from textile composites offer enhanced protection with lightweight, but the discontinuity of the reinforcing materials is a potential problem affecting the helmet performance. This work uses 3D angle-interlock fabrics to provide reinforcement continuity, and evaluates 3D through-the-thickness angle-interlock (TTAI) fabrics to study the influence of fabric structural parameters on fabric mouldabilty and ballistic performance for ballistic helmet application. The mouldability was measured through experiments and modelled numerically, and the ballistic impact test was carried out to identify the optimal fabric structures for constructing ballistic helmet shells. The results show that increase in weft density of the TTAI fabrics causes decrease in the mouldability of the TTAI fabrics, and that the addition of wadding yarns into the TTAI fabrics has little influence on fabric mouldability compared to the conventional TTAI fabrics with the same weft density. However, the involvement of wadded TTAI fabrics demonstrates a 34% increase in ballistic energy absorption and 3% higher estimated ballistic limit over the conventional counterpart. Taking both mouldability and ballistic protection into account, the wadded TTAI fabric structure is an effective continuous reinforcement for ballistic helmet shells, offering required mouldability and improved ballistic performance.

“…It was observed that the frictional heat during the impact process can reach 200 C. 26,27 Even though the ceramic composites may insulate against some of the heat from the bullet, the frictional heat between the shattered ceramic particles and the UHMWPE from the surface layer can still decrease the integrity of the UHMWPE layer. According to the research conducted by Yang et al, 13 when UHMWPE is used as the ballistic plate surface layer, the friction between the bullet and the ballistic plate can generate localized high temperatures, causing the UHMWPE in the surface layer to undergo melting. Based on the research of Kromm et al 28 fiber strength and modulus of the surface layer (UHMWPE, thickness less than 1.2 mm) are 50% compared with those at room temperature under quasi-static conditions based on the simulation scheme and results reported in the above literature.…”

This paper investigates the impact of hybrid fiber structures on the ballistic performance of columnar ceramic/interlayer hybrid fiber composites. Three hybrid fiber composites and one single fiber‐component composite were fabricated. The accuracy of the numerical model was validated through quantitative analysis of matching micro‐CT images with simulation results. The error of the back convex height (BCH) values between the numerical simulation and the micro‐CT was only 2.8%. The error of delamination area at four thickness positions is only 0.7%, 14.7%, 0.3%, and 5.3%, respectively. The quantitative study on the ballistic performance of ceramic/fiber composites indicates that all hybrid fiber composites provide enhanced penetration resistance, with the sandwich structure outperforming the rest. Compared with the C‐U sample, the bullet's remaining velocity and the BCH in the C‐(A/U/A) sample were significantly improved, with reductions of 195 m∙s−1 and 16.6 mm, respectively. During the penetration process, the ceramic/fiber composites mainly exhibited damage failure mechanisms such as ceramic crushing to form ceramic cones, shear failure, and shear‐tensile‐delamination mixed failure. The energy absorption rate (EAR) of ceramic failure was 54.1%–60.2%, the EAR of tension was 12.5%–20.9%, and the EAR of the tension‐delamination‐shearing mixed model was 21.9%–32.8%.Highlights The numerical model is quantitatively validated with micro‐CT results. Ballistic resistance and EARs in six stages are quantitatively analyzed. C‐(A/U/A) composite has superior ballistic resistance compared to C‐U.

“…Thus, hybrid configurations with woven fabric layers or nonwoven felt layers on the striking face would exhibit higher energy absorption. 29 To the best knowledge of the authors, few published studies have focused on the effect of intra-layer and intra-yarn hybridization on the ballistic performance of woven fabrics, and the differences between hybrid strategies remained unclear. Motivated by the above literature review, the present study aimed to systematically compare the ballistic responses of hybrid aramid/ UHMWPE woven fabrics and provide a comprehensive understanding of the hybridization effects.…”

The increasing demand for advanced personal protection systems has motivated a considerable interest in hybrid woven fabrics and textile composites. However, the effectiveness of the combination method of fibers on ballistic performance remains uncertain, leaving the selection of an appropriate hybridization strategy unresolved. This study conducted a thorough comparison of the ballistic responses of hybrid aramid/ultra-high molecular weight polyethylene (UHMWPE) woven fabrics, aiming to provide a comprehensive understanding of the hybridization effects. Specimens with inter-layer, intra-layer, and intra-yarn hybrid configurations were manufactured, and ballistic impact tests were performed via a light-gas gun. The residual velocity, energy absorption, dynamic penetration process, and perforation modes of the hybrid specimens were recorded at two selected impact velocities and then compared with those of non-hybrid specimens. The results demonstrated that the enhancement effect of hybridization varied with hybrid configuration and impact velocity. The interlacing of aramid yarns and UHMWPE yarns in intra-layer hybrid specimens did not promote the breakage of UHMWPE fibers, which was responsible for the inferior ballistic performance. In contrast, inter-layer hybridization and intra-yarn hybridization could overcome the insufficient friction of UHMWPE and the low mechanical properties of aramid, resulting in superior ballistic performance.
