The article gives recommendations on the calculation and design of the restoration of bearing capacity of the buildings that have significant deformations of the walls from brickwork. The method with the use of fibre-reinforced plastic (FRP), is a composite material made of a polymer epoxy matrix reinforced with carbon fibres. In addition, the accumulated experience, based on the results of the tests (static and dynamic on the fragments of structures and mock-ups of buildings) is considered, as ell as the applications on the real objects.

Ultra High Molecular Weight

Ultra-high molecular weight polyethylene (UHMWPE) has been reinforced with type I and type II carbon fibres by a compression moulding technique. The composite is found to have markedly improved tensile and flexural properties, suggesting that it would be useful both as an improvement to current polyethylene components and as an inducement to more elaborate designs using the composite material.

Strength Improvement

Lightweight and strong composite material beams are increasingly sought to quickly, easily, and cost-effectively transport and setup a variety of constructions such as bridges, cabins/ stores/shelters, vehicles etc. For structural beams produced as conventional laminated composite materials, their weak areas tend to occur at intersections such as web-flange junctions due to absence of fibres bridging the interconnections. This drawback can however be overcome with development of profiled 3D textile reinforcements having combination architectures and constituent web-flange parts inherently mutually interconnected through fibre interlacement. In addition to general strength improvement, beams containing such novel reinforcement architectures also show increased energy absorption capability due to the mutual web-flange integration at the junctions. An ‘I’ and a ‘flanged-triangle’ cross-section beams were produced by a novel non-conventional weaving method, using carbon fibres as reinforcement, and their energy absorption capabilities were tested. These beams respectively absorbed over 50% and 300% more energy per weight in bending, compared to metal counterparts. This paper presents some relevant aspects of these innovative beams.

Pyrolysis Process

Abstract The article deals with the influence of thermal pyrolytic degradation on mechanical properties of carbon fibres used in the production of composite material. The carbon fibre has been chosen as the reinforcement of composite and the resin formed a matrix (binder). During the pyrolysis process, the resin was eliminated and the carbon fibre was separated. Pyrolysis was carried out at temperatures of 450 °C, 550 °C and 650 °C. Subsequently also tensile tests were performed on the treated material to compare the mechanical properties of the fibres prior to pyrolysis and after decomposition. The results showed negative influence at the selected temperatures during the pyrolysis treatment on the mechanical properties of the carbon fibres.

Selection Of

Carbon fibres and Kevlar fibres are among the commonly used fibres in the composite industry. As carbon fibres usually known for its superior strength, its low impact resistance limited its application in the industry. However, further research found that combining the high strength fibres with more ductile fibres like Kevlar could improve the material’s impact resistance. This hybrid effect was also found to be most effective by using intra-ply woven hybrid fibres in the composite. In this work, hybrid composite material was fabricated by using woven carbon-Kevlar cloths with epoxy matrix and the mechanical properties are determined at 0 ̊, 45 ̊ and 90 ̊. The hybrid composite material was found to have highest tensile strength at 0 ̊ (carbon) direction. As the material’s strength and tensile behaviour are different at every fibre types, the selection of fibre direction of the woven cloth in loading is an important criteria in any applications.

Compound Tial

In order to improve the mechanical properties of an intermetal1ic compound TiAl, a composite material of TiAl involving a second phase Ti2AIN was prepared by a new combustion reaction method. It is found that Ti2AIN (hexagonal structure) is a rod shape as shown in Fig.1 and its side surface is almost parallel to the basal plane, and this composite material has distinguished strength at elevated temperature and considerable toughness at room temperature comparing with TiAl single phase material. Since the property of the interface of composite materials has strong influences to their mechanical properties, the structure of the interface of intermetallic compound and nitride on the areas corresponding to 2, 3 and 4 as shown in Fig.1 was investigated using high resolution electron microscopy and image processing.
