“…This way seems to be a more advisable one and in many cases it has resulted in the development of quite efficient joints: half-stitch connecting tips [20][21][22][23][24], stepped adhesive bonded joints [25][26][27], polymer-to-metal matrix transition in the interface area with fibers remaining continuous [28], etc.…”

Introduction. At present, composite materials (CM) have found extensive applications in almost every manufacturing industry. Despite numerous problems relating to mechanics, strength, design and manufacturing of composite structures are important and have to be solved, it can be stated that the most significant task is to develop design and engineering solutions (DES) for jointing high-loaded components of fiber-reinforced composites. When composites were used to make some auxiliary or low-loaded structural members, mechanical fastening and adhesive bonding were quite efficient.However, as the necessity of designing and manufacturing heavy-duty CM assemblies, especially in the aerospace industries has arisen, the problem of jointing has gained in significance for the following reasons:-The use of conventional mechanical fastening and methods of its installation leads to cutting of a considerable portion of fibers, which requires certain compensation and revision of the CM structure.-Adhesive bonding of high-loaded components under large-scale production conditions is difficult to implement because of stringent requirements for process parameters and workmanship, lack of reliable nondestructive testing methods, impracticability of repair, and design engineers' doubts about adhesive bonded joints, especially if such joints are critical for the product safe operation; polymeric composites have lower bearing, shearing, and interlaminar shear strength characteristics. The reported bearing strength values of 400 to 700 MPa [1][2][3][4][5][6][7][8] were obtained on very thick laboratory specimens where the influence of the scale factor greatly decreases.-Machining of up-to-date composites is a difficult and expensive process that requires advanced cutting tools and equipment [2,[9][10][11]. The problems of standardization, assurance and monitoring of hole accuracy and machined surface quality are still to be solved.
