“…During CAI loading on continuous fiber reinforced composite material, the buckling of fiber, fiber‐matrix debonding and subsequent propagation of delamination caused by early pre‐impact damage may be accountable for composite failure. [ 39 ] Because of having wavy placement of filaments (up and down interlacement of longitudinal and horizontal filaments) in woven carbon fabric, the manufactured carbon/epoxy composite is more susceptible to fiber buckling. [ 40 ] The inclusion of PEEK particles in matrix may result in the formation of micro composites that resist micro buckling of the fiber.…”

Due to the intrinsic brittleness, low velocity impact (LVI) causes internal invisible damages that drastically degrade the structural qualities of carbon/epoxy composites. The addition of pre-formed immiscible thermoplastic filler in thermoset matrix offers various advantages over miscible phase separated thermoplastic filler. In this work, poly ether ether ketone (PEEK) micro particles were used to improve the toughness of the carbon/epoxy composite. Mechanical stirring was used to disperse the particles. Composite was fabricated using hand lay-up process followed by compression molding. The effect of PEEK particles was assessed using in-plane v-notched rail shear characteristics, drop weight impact, and compression after impact strength. The addition of PEEK particles significantly improved the in-plane shear strength and damage tolerance of the carbon/epoxy composite, according to the results.

“…Firstly, the felt/felt layered needled structure, [8][9][10] which has a low volume density and weak in-plane mechanical properties, is mainly used as an anti-thermal insulation material; second, the felt/ base cloth layered needled structure. [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.…”

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.

In this work, a new type of epoxy foam‐filled 3D woven spacer composites (FF‐3DWSCs) was designed and manufactured by self‐made 3D loom and foaming technology. The low velocity impact behaviors, residual compressive properties and strengthening mechanisms of epoxy foam were systemically investigated. As the results, the FF‐3DWSCs showed higher impact load of 4000–5200 N than that of 3D woven spacer composites (3DWSCs) (2800–4300 N) at the energy from 10 to 40 J. The residual compressive strength of FF‐3DWSCs (23.85 MPa) was maintained at about 80% after 30 J energy impact. Due to the good compatibility of the epoxy foam and the epoxy resin and the synergistic effect between the pile yarn and the epoxy foam, the interface between epoxy foam and fiber/epoxy was strong. Therefore, the novel FF‐3DWSCs proposed here exhibited excellent impact properties and energy absorption capacity and can be used as a candidate material in the field of high‐performance composites.
