A composite groove structure with high specific strength and light weight has great potential in industrial application, but few studies on this have been carried out due to the fact that it is difficult to fabricate by one of the existing methods. The purpose of this work was to propose a novel method combining 3D printing and filament winding to manufacture the groove structure and study the link between its mechanical strength needs and fabrication parameters. Specifically, filament winding and 3D printing were used to fabricate the cylinder part and complex ring slot part of the groove structure, which is difficult to fabricate by winding. The combining method took advantage of the winding’s high efficiency and the printing’s high forming degree of freedom. The specimen was taken from the structure and submitted to a short beam test to determine its interlaminar shear strength, whereas thermal tests were carried out to evaluate its mechanical performance under high temperature. The interlaminar shear strength reached 6.694 MPa at a fiber orientation of 90°, a heating temperature of 245 °C and a thickness of 0.5 mm. The SEM photo showed some voids and gaps and typical failure in the failed specimen. DMA and TGA were carried out to investigate the performance under high temperature, from which the storage modulus lost half to 120 °C. Overall, the proposed combining novel method offers a new direction in the fabrication of continuous fiber-reinforced thermoplastic composites’ groove structure.

“…The construction of the fifth-generation fighter F-22 Raptor includes dispersion-and continuous reinforced composites based on aluminium and titanium alloys made with the AFP (Automated Fibre Placement) method in addition to polymer composites made with the RTM (Resin Transfer Moulding) technique. It is also possible to substantially reduce the time needed for manufacturing high-performance carbon composite parts by utilising compression resin transfer moulding (CRTM), thus ensuring a further decrease in production costs [10,11]. The Lockheed F-22 Raptor is an example of an airframe design, where high-temperature BMI (bismaleimide) composites were used.…”

In this work, an attempt was made to apply laser surface technology for enhancement of the properties and strengthening the material with addition of ceramic phases in the form of silicon and tungsten carbide particles, leading to a remarkable increase in hardness. Thanks to rapid cooling caused by heat being transferred to the cold substrate, an advantageous, fine-grained structure develops, showing higher gradient morphology; furthermore, the surface layers obtained with laser alloying offer greater heat-resistance and anti-corrosion properties, as well as high wear resistance in addition to the aforementioned hardness, which increases by as much as 15% for the AlSi9Cu4 alloy compared with the alloy after standard heat treatment. Such an increase in the values of the mechanical properties makes it possible to use the investigated alloy in applications including, e.g., recyclable thermally exposed surfaces, such as pistons in internal combustion engines, which enables further decrease in the weight and the thermal expansion with simultaneous increase in the strength, reduction in fuel consumption, and increase in carrying load, speed, and range, which generates the need for further research into the area.

Automated fiber placement (AFP) is a method to manufacture complex composite parts in an automatable and scalable process. Thermoplastic in situ AFP has received more attention in recent years for its use in high-performance, aerospace applications that use low-melting polyaryletherketone (LM-PAEK) composites. Although in situ AFP is a promising technology for the automated and economical manufacturing of composites, the production of a mold is still a considerable expense. Using large-scale additive manufacturing, molds can be manufactured in a short time frame for a fraction of the cost of traditional molds. By using polyamide 6 (PA6), a polymer incompatible with LM-PAEK, a bond can be created, which holds a laminate in the desired form during production and allows for demolding. Due to the thermoplastic nature of PA6, a mold can be manufactured using large-scale, extrusion-based additive manufacturing. This study investigates the suitability of 3D-printed molds composed of PA6 for the AFP of CF/LM-PAEK laminates. To this end, peel tests and shear tests were conducted to investigate the influence of the process temperature, the area of heating and the consolidation pressure on the bond of these incompatible polymers. A shear strength of up to 2.83 MPa and a peel strength of up to 0.173 N·mm−1 were achievable. The principal suitability of PA6 as a mold material for the AFP of CF/LM-PAEK was demonstrated.
