“…One of the techniques that makes it possible to produce the research object is the Tailored Fiber Placement (TFP) technology. It consists of placing the textile material in an appropriate, preprogrammed place [15]. In the case of the tests presented below, it is done with a computer embroidery machine.…”

The main purpose of the article is to present the new possibilities of producing composite reinforcement with the use of a computer embroidery machine. This kind of production is in line with the principles of sustainable development. The study below presents the results of strength tests of composites containing sevenfold embroidery systems. Each variant included different directions of arrangement of individual layers as a reinforcement. Flax roving was used to strengthen the composite. Flax fibers are characterized by the highest strength among all-natural fibers, at the level of 50–80 cN/tex. The composite was made using the vacuum bag method, using epoxy resin. The embroidery was made on a ZSK embroidery machine, type JCZA 0109-550. The test material was subjected to strength tests—tensile strength, tensile elongation, and bending strength, on the INSTRON machine. Based on the research, it can be concluded that the arrangement of the roving in the direction of the tensile force allowed to obtain the best mechanical properties.

“…However, additional reinforcement of the preform by patching allows to achieve the strength of samples up to 94% of the strength of the holelesssample with a slight increase in weight. El-Dessouky et alstudied the technology of manufacture oflaminated plastics with the hole based on the thermoplastic binder [37]. The authors of [38] presented the results of studies of samples with holes in tension and cyclic tests.…”

This paper contains an overview of world trends in the development of the TFP technologyenabling 3D printing of carbon fiber reinforced plastics. The review of the equipment used for the automated preformpatching is included. Primary factors restraining the large-scale implementation of the TFP technology in the manufacture are identified, and prospective research trends for further development of the technology are proposed.

Permanent Deformation and Stiffness Degradation of Open Hole Glass/PA6 UD Thermoplastic Composite in Tension and Compression

et al. 2021

UD glass/PA6 coupons with an open hole are subjected to tensile and compressive loading. Three layups: [0/90]5s, [+45/−45]5s and [+45/0/−45/90]3s with a shape based on ASTM D5766 were tested. Both monotonic loading as well as loading–unloading–reloading tests were executed. The strain field on the sample surface was measured with digital image correlation. This allowed identifying the distribution of the strain field during loading, permanent deformation and the evolution of the sample elastic modulus. This information is not frequently measured. Yet, it is vital for the development and validation of advanced failure models. The results indicate that the thermoplastic matrix allows large plastic deformation under tensile loading for the specimens with layup [+45/−45]5s. In addition, the specimen elastic modulus reduces by about 70%. The other layups show minor permanent deformation, while the elastic modulus reduces by up to 15%. Furthermore, the quasi-isotropic laminate shows a significant post-failure load-bearing capacity under compression loading. The results are complemented with post-mortem damage and fracture observations using optical microscopy and ultrasound inspection.
