“…Of particular relevance in the development of products from CFRPs is the ability of structural materials to withstand alternating cyclic and impact loads, which is determined by their interlayer fracture toughness (crack resistance). Low values of this indicator can provoke a serious decrease in the rigidity and strength of CFRPs over time that will lead to catastrophic destruction of the entire structure 5,6 …”

“…Low values of this indicator can provoke a serious decrease in the rigidity and strength of CFRPs over time that will lead to catastrophic destruction of the entire structure. 5,6 A well-known problem in creating CFRPs based on heat-resistant matrices is to overcome the objectively existing contradiction between high heat resistance and crack resistance. The higher the heat resistance of the matrix, the more brittle and, therefore, prone to cracking, the composite material becomes.…”

Heat resistant thermoplastic matrices offer potential advantages over thermoset polymers and represent a promising alternative in advanced composite applications. In the present work, the properties of carbon fiber reinforced plastics (CFRPs) based on the developed semicrystalline polyimide R-BAPB were studied and compared with those of highly heat-resistant thermoplastic polymers such as amorphous polyetherimide Ultem-1000 and semicrystalline polyetherketone PEEK. To obtain CFRP, an approach was used basing on the uniform distribution of polymer powders on continuous carbon fibers by electrostatic spraying followed by their impregnation in heated calenders and hot pressing. The thermal and thermomechanical properties of CFRPs based on mentioned above polymers were studied. The effect of temperature on the mechanical behavior of CFRPs, including flexural properties and interlaminar fracture toughness G 1C , was investigated as well. CFRPs based on PEEK and R-BAPB are found to have the highest thermal stability and heat resistance.The maximum flexural strength, which practically does not change in a wide temperature range from À50 to 180 C, is observed for CFRP based on R-BAPB polyimide. Among the investigated CFRPs, the highest value of interlaminar fracture toughness is shown by CFRPs based on semicrystalline R-BAPB.

In this work, there was developed a three-axis CNC felting machine with one barbed needle. Felting is a kind of needle-punch technology for joining fabric stack by broken and pulled fibres. The density of needle hits is a valuable factor to make the required shear strength of polymeric composite materials in the specified places. Using the glass-fibre reinforced plastic (GFRP) with plain weave felted fabric, a noticeable decrease in strength with an increase in the needle hits density from 0 to 90 cm−2 is shown. For a laminated GFRP made from a stack of fabrics, it has been shown that the shear strength of the single-lap joint and the interlaminar shear fracture toughness GIIC significantly increase with an increase in the needle hits density. This is important for modern aircraft shells exposed to random low-velocity impacts during ground or flight operations.
