Проведеними дослiдженнями отримано можливiсть виготовлення теплоiзоляцiйних матерiалiв з сухостiйної деревини сосни для облаштування примiщень. Сировиною для їхнього виробництва є деревнi волокна, якi формують у плоскi плити. Встановлено механiзми процесу теплоiзоляцiї при передаваннi енергiї через матерiал, що дає можливiсть впливати на цей процес. Доведено, що процеси теплоiзоляцiї полягають у зниженнi пористостi матерiалу. Так, зi зменшенням об'ємної маси матерiалу, теплопровiднiсть зменшується, i навпаки. Проведено моделювання процесу передавання тепла при спучуваннi вогнезахисного покриття, визначено залежностi теплофiзичних коефiцiєнтiв вiд температури. За отриманими залежностями розраховано коефiцiєнт теплопровiдностi для виробiв з сухостiйної деревини сосни, який сягає 0,132 Вт/(м•K). У разi оброблення виробiв з деревини клейовою композицiєю зменшується до 0,121 Вт/(м•K), а при створеннi теплоiзолювальних плит iз деревної шерстi знижується до 0,079 Вт/(м•K) вiдповiдно. Особливостi гальмування процесу передавання тепла до матерiалу, що виготовлений з деревної шерстi i клеєного в'яжучого, пов'язано з утворенням пор. Це пояснюється тим, що в не великих порах вiдсутнiй рух повiтря, що супроводжується перенесенням тепла. Теплопровiднiсть однорiдного матерiалу залежить вiд об'ємної маси. Так, зi зменшенням об'ємної маси матерiалу до 183 кг/м 3 теплопровiднiсть зменшується в 1,67 рази, i навпаки при застосуваннi дошки теплопровiднiсть знижується лише в 1,1 рази. Це дозволяє стверджувати про вiдповiднiсть виявленого реальному механiзму теплоiзолювання i виявлених умов формування властивостей матерiалу на основi деревної шерстi i неорганiчного та органо-мiнерального в'яжучого та практичну привабливiсть запропонованих технологiчних рiшень, а саме застосування низькоякiсної деревини. Останнi, зокрема, стосуються визначення кiлькостi складової в'яжучого. Таким чином, є пiдстави стверджувати про можливiсть спрямованого регулювання процесiв формування деревинних теплоiзоляцiйних матерiалiв шляхом використання деревної шерстi i неорганiчного та органо-мiнерального в'яжучого, якi здатнi утворювати на поверхнi матерiалу вогнезахисну плiвку Ключовi слова: теплоiзоляцiйнi матерiали, деревна шерсть, теплопровiднiсть, теплоємнiсть, неорганiчне i органо-мiнеральне в'яжуче

“…Although basalt composites are a relatively new material and extensive research on their properties is still needed [ 1 , 8 , 20 , 21 ], it has been already proved that using them is involved with multiple benefits when comparing to more common types of FRPs (such as GFRP or CFRP). Advantages of basalt fibers in regards to other types of fibers have been underlined in the article [ 22 ]. It is worth mentioning their advantages as follows: higher electrical insulation than in the case of glass fibers, high corrosion resistance and chemical stability, high acoustic and thermal insulation properties or good compatibility with metal, plastic and carbon fibers.…”

Nonlinear Analysis of Compressed Concrete Elements Reinforced with FRP Bars

Although fiber reinforced polymer (FRP) bars have proved their usefulness in the case of reinforced concrete flexural elements, there are still limited data on their performance in such structures under compression. Despite multiple benefits of using FRP bars as the reinforcement in concrete elements, their potential application as main reinforcement in compressed elements is still very controversial, mainly due to the limited amount of published research results. The presented work partly fulfills this knowledge gap. Two series of theoretical analyses—one based on the stress distribution in the cross-section and the second using the finite elements method (FEM)—with reference to the experimental results are presented. The analyses concern basalt FRP, glass FRP, and steel-reinforced concrete elements under axial compression. There are derived calculations of load–displacement relations and stress values in bars. Damage progression was analyzed as well. Main findings are as follows: (1) a good agreement between calculated failure loads and experimental results has been achieved; (2) potential negative influence of FRP reinforcement on the compressive capacity of the reinforced element should not be neglected; (3) nonlinear FEM analysis is useful in predicting the maximum value of load and damage zones; (4) stress values of only about 100 MPa (much lower than their compressive strength value) were obtained in non-metallic bars. The results might be useful for the further establishment of design rules.

“…Therefore, the basalt fabric was selected for testing. Basalt fibers and products made of them are characterized by a low thermal conductivity, low moisture absorption, and good thermal resistance [5][6][7][8]. These fibers have high thermal resistance, which enables them can be used in the temperature range from −260 to 800 • C. Due to the non-flammable properties that characterize basalt fibers, the materials made of them are resistant to flames for a very long period of time.…”

Study on Some Thermal and Electrical Properties of Basalt Fabric Modified with Metal and Ceramics as a Result of Magnetron Sputtering

The main aim of the research was to compare the values of some thermal and electrical parameters obtained for a basalt fabric modified with the metal and ceramics coatings. The surface modification of basalt fabric was made by using a magnetron sputtering technique. Chrome and zirconium(IV) oxide coatings were deposited on the fabric surface. The thermal and electrical properties of selected fabrics were determined. In order to assess the comfort properties of fabrics, the thermal resistance of materials was analyzed. Instrumental color measurement was used for an assessment of the surface of modified and unmodified basalt fabric. Using a non-contact digital color imaging system, DigiEye, an original method of samples surface analysis was presented. As a result of research, the modification of basalt fabric surface for applications in a hot work environment enabled the improvement of thermal properties in relation to the references samples. The first level of protection against contact heat for a contact temperature of 100 °C was obtained for the zirconium(IV) oxide-modified basalt fabric. The first level of protection against radiant heat was obtained for all samples. The highest value for the heat radiant resistance was obtained for the chrome-modified basalt fabric.
