В настоящее время лыжный спорт пользуется большой популярностью, поэтому спрос на лыжи постоянно возрастает. В связи с чем развитиенационального лыжестроения является актуальным для нашей страны направлением. Лыжная индустрия развивается быстрыми темпами и на смену деревянным лыжам пришли пластиковые. Одним из составляющих компонентов лыж является полимерный композиционный материал (препрег). Поэтому сейчас производство препрега набирает обороты, создаются новые материалы на их основе. Проведенные исследования позволили разработать рецептуру и лабораторную технологию связующего на основе вторичных терпеноидных продуктов для изготовления препрега с дальнейшим использованием его при производстве пластиковых лыж. Полученные экспериментальные образцы лыж на производственных площадях филиала «Телеханы» Республиканского производственно-торгового унитарного предприятия «Беларусьторг» Управления делами Президента Республики Беларусь, по своим эксплуатационным свойствам находятся на уровне нормативных показателей. Currently, skiing is very popular. Therefore, the demand for skis is constantly increasing. The development of the national ski industry is an important direction for our country. The ski industry is developing rapidly and plastic skis have replaced wooden skis. One of the components of skis is a polymer composite material (prepreg). Therefore, now the production of prepreg is increasing, many new materials on its basis are created. Our research has allowed us to develop a formulation and laboratory technology of a binder based on secondary terpenoid products for the production of prepreg for its further use in the production of plastic skis. Experimental samples of skis obtained at the production arears of the «Telehany» of the Republican production trade unitary enterprise «Belarustorg» of the administrative department of the President of the Republic of Belarus are at the level of standard indicators for their operational properties.

One of the significant innovative technologies is the creation of large-sized structures that work for a long time in space and meet stringent restrictions on overall mass characteristics. Among these structures, in the first place, is the section of bearing truss (BT). This article presents the results of experimental studies of sectors of load-bearing trusses of mesh design for compression. Recently, composite mesh cylindrical shells are used as spacecraft housings. The mesh shell is a supporting structure to which the instruments and mechanisms of the spacecraft are attached. The truss section is made of cross-linked polymer composite material with carbon fibers. The objective of the tests is to confirm the possibility of creating a lightweight mesh construction using a carbon fiber reinforced polymer composite material. To achieve this goal, the authors were assigned the following tasks: selection of carbon filler of polymer composite materials (PCM); selection of PCM binder; determination of the degree of carbon fiber reinforcement; choice of the number and orientation paths of spiral ribs, number of ring ribs and the sizes of individual ribs. As a result of the research, the calculated indicators for ensuring the bearing capacity and stiffness under the application of axial compressive load were obtained. At the same time, with the determination of bearing capacity, the deformation characteristics of the structure were twice determined in order to confirm their repeatability, as well as linear nature of the dependence of axial and radial deformations as a result of the applied load.
