“…[11][12][13] Using unidirectional cloth, 12,14 woven cloth, 15 or braided cloth 16 as the base cloth, which has better in-plane performance and is commonly used in structural components such as brake disc materials, engine nozzles, throats, 17,18 and so forth. Recently, Yao et al 19,20 proposed a new needled structure and composite without felt that used half-cut cloth instead of felt, presented excellent interlaminar and in-plane performance, and was expected to be used as a material for high-speed aircraft radome covers. There have been many research reports on the application of spread tow plain weave fabric in laminated composites, [21][22][23] which have shown that laminated composites using spread tow plain weave fabric can achieve better in-plane mechanical properties.…”

Due to the high fiber volume fraction of carbon fiber spread tow plain weave fabrics, it is difficult for short fibers to be brought into the thickness direction to form needled fiber bundles during the needling process. The interlaminar performance of the carbon fiber spread tow needled preform is weak, and the in‐plane damage is also severe. Responding to this issue, this article proposed a new method for preparing carbon fiber spread tow needled preform based on short yarn needling, which was expected to manufacture high‐performance carbon fiber spread tow needled preform and composite. We conducted experimental research on the preparation and structural characterization of the preform, as well as the Mode I interlaminar mechanical properties and in‐plane tensile properties of composites. The results showed that the fiber volume fraction of the preform significantly increased, reaching to 55.7%–56.1%, which was 25.5%–25.9% higher than that of traditional needled preform. The Mode I interlaminar property of carbon fiber spread tow needled composite reached to 905–4376 J m−2, which was improved by 29.3%–525.1% and 125.8%–1054.6% compared to traditional needled composite and laminated composite, respectively. At the same time, the tensile strength and tensile modulus were also improved by 191.5%–212.2% and 66.2%–78.1% compared to traditional needled composites. The preparation method of carbon fiber spread tow needled preform based on short yarn needling has laid the foundation for the 3D printing molding of dry fiber fabrics and is expected to be applied to high‐quality needling of high thickness and large curvature‐shaped fabric preforms.Highlights A novel method was proposed for preparing high‐performance carbon fiber spread tow needled preform based on short yarn needling. The fiber volume fraction of novel carbon fiber spread tow needled preform significantly increased, reaching to 55.7%–56.1%. The GIc of the novel carbon fiber spread tow needled composite was improved by 29.3%–525.1% compared to the traditional needled composite. The tensile strength and tensile modulus were also improved by 191.5%–212.2% and 66.2%–78.1%, compared to traditional needled composites.

“…Because the felt layer is airy, so the volume density of needled fabrics formed by using felt is small, and the interlaminar property is also weak, which cannot meet the mechanical performance requirement of hypersonic vehicle structural and functional integration components. Yao T et al [12][13][14] presented a new none-felt needled preform fabric, which enhanced the volume density of needled fabric, and greatly improved the in plane and interlaminar mechanical property, which was expected to satisfy the application requirements of hypersonic vehicle. Interlaminar interfacial performance.…”

The needled/tufted interlocking fabric is a new fabric structure. At present, the mode II interlaminar shear behavior of needled/tufted interlocking composite has not been clarified. In this work, the needled/tufted interlocking fabrics and reinforced composites were fabricated, and the interlaminar shear behavior of mode II was studied experimentally and numerically, the mechanism of tufting effect on interlaminar shear properties of needled composites was revealed. The study found that the interlaminar shear properties of needled/tufted interlocking composites were greatly improved by tufted fiber bundles. The maximum failure load of the needled/tufted interlocking specimen increased 108.93%, and the interlaminar shear stress of the needled/tufted interlocking specimen improved by 89.39%. The interlaminar shear strength increased linearly with the increase of tufted fiber bundle implantation volume. The implantation pattern of tufted fibers had effected on interlaminar shear property. Under the same implantation volume, the thinner tufted fiber bundles and more implantation points were more beneficial to improve the interlaminar shear performance. The typical shear failure modes included matrix cracking, fibers pullout, and brittle fracture of tufted fiber bundles and needled fiber bundles. Moreover, a numerical simulation model of interlaminar shear behavior based on three cohesive zones (TCZMs) was proposed. The predicted displacement-load curves were highly in accord with the experiments. The error range was controlled within 1.08% - 3.76%. The simulation model could predict the mode II shear behavior of needled and tufted interlocking composites effectively, which was helpful to the early manufacturing process design of needled and tufted interlocking fabrics.
