The use of technology of braiding in production of structural elements of polymer composites materials

Currently, the use of technology of polymer composites materials using braided preforms, mastered a number of foreign companies, and has applications in both aerospace engineering, and in a number of civilian industries. These are characterized by materials considerable resistance to delamination and impact, high fatigue performance, high strength near the holes. The use of braided preforms can simplify the problem compounds in prefabricated structures allow for the automation of production, provide high speed and efficiency of the manufacturing process the polymer composites materials.

Joining materials of different types used in constructions subjected to pulse loadings

The present investigation was aimed to joining materials of different types used in constructions subjected to pulse loadings. It was stated that the conventional approach to the selection of high-strength adhesive medium does not provide the required level of workability of adhered joints. To solve this problem, the joining technique based on application of an adhering layer with a high deformation capacity is offered. In the course of experiments it was verified that the behavior of adhered constructions under pulse loading depends on the elasto-plastic properties of materials subjected to joining.
