“…The performance of composites itself is mainly affected by the lay-up process and the fiber volume fraction, and it is impossible to improve its mechanical properties through post-processing. Therefore, in-depth excavation of composite structural bearing potential and failure mode provides extremely important engineering value for structural lightweight design [3].…”

Carbon fiber composite structures have a broad application prospect in oilfield completion tool module connection. However, the material failure mechanism is still unclear. In this paper, the mechanical properties and failure mode of T700/7901 composite J-type structure are investigated from experimental and finite element perspectives. Firstly, the load-carrying and failure properties of the structure were analyzed through typical mechanical property experiments such as tensile, bending, and compression, and the fiber, matrix damage, and delamination damage are the main reasons for the failure of the mechanical properties of the material. Secondly, a numerical model of the progressive damage ontological relationship of the composite material was established, and the accuracy of the model was verified by combining the experimental results. Based on the above study, this paper proposes the failure mechanism and optimization of composite J-type, which provides useful guidance for the design of fiber composite structures for oilfield completion tool types in the future.

Carbon fiber reinforced polymer (CFRP) exhibits different heat transfer phenomena along the fiber direction and the transverse direction during the heat transfer process due to its anisotropic thermo‐physical properties, which makes it difficult to quantitatively analyze the overall thermal performance of CFRP with different ply angles. A thermal resistance network model of composite material considering fiber ply angle and heat transfer direction was developed based on the series–parallel resistance computing method, and it was applied to describe the test results measured by the thermal response tests of unidirectional carbon fiber laminates. Thermal resistance Rx along the heat transfer direction and Ry transverse to the heat transfer direction calculated by the proposed model, which are related with the thermal response of the specimen, can be utilized to reflect the temperature values and temperature distribution maps. It was found that as the fiber ply angle θ increases from 0° to 45°, thermal resistance in the x‐axis direction increases from about 0.13 K/W to 2.56 K/W, while thermal resistance in the y‐axis direction decreases about 48.7%. As a result, major axis of quasi‐ellipse temperature profile changes by about +45° relative to the x‐axis.Highlights A CFRP thermal resistance network model considering ply angle was proposed. The series–parallel thermal resistance method is used to calculate Rx and Ry. The ply angle from 0° to 45°, Rx increases several times and Ry decreases by half. Major axis of elliptic temperature curve changes by +45° relative to the x‐axis.

Improving the interfacial adhesion of carbon fiber (CF)/polymer composite is an urgent demand to enhance its mechanical properties. A kind of poly(aryl ether ketone) with carboxyl groups (PAEK‐COOH) was newly synthesized. PAEK‐COOH is similar to the thermal properties of PPEK matrix. Hydroxyapatite (HAp) was easily dispersed in an NMP solution containing PAEK‐COOH. Different kinds of hybrid sizing agents were obtained for preparing the prepreg through the solution impregnation. The hot‐pressing method was employed to produce the laminated composites. Flexural strength, flexural modulus and interlamellar shear strength (ILSS) of 0HP@CF/PPEK composites were improved by 8.8%, 17.3%, and 14.7%, respectively, in comparison to desized CF/PPEK. The interface bonding between CF and PPEK was improved by the addition of PAEK‐COOH sizing agent. Meanwhile, compared with desized CF/PPEK laminates, flexural strength, flexural modulus and ILSS of 5HP@CF/PPEK composites were enhanced by 63.5%, 87.4%, and 40.9%, respectively. The crack propagation path became dispersed and the stress was effectively absorbed when the sizing agent containing nano‐hydroxyapatite particles. By characterizing and reconstructing the transverse and longitudinal fracture in composite materials, the failure process of the composites under the action of stress was explained, and the interface theories of CF reinforced polymer were further explored.Highlights A kind of polyaryl ether ketone containing carboxyl functional group (PAEK‐COOH)was newly synthesized. HAp was distributed in the polymer sizing agent to obtain a HAp/PAEK‐COOH hybrid sizing agent. The interfacial adhesion of CF/PPEK composite was greatly improved by the hybrid sizing agent.
