In a composite material that uses fibers as reinforcement, the breakage of the matrix is produced jointly with the separation of the fiber from the matrix. The mechanical behavior of the interface describes how fibers can work stabilizing the cracking process. The interface is the medium that puts the fiber on load, b…
Restoration, strengthening and rehabilitation of buildings becomes one of the more interesting aspects of the use of composites. Construction industry has not yet accepted the wide structural use of these new materials because it does not know the advantages of composites in comparison with traditional materials, such…
This article is based on works, carried out at the IETcc, aimed to evaluate the behaviour of concretes reinforced with acrylic polyacrylonitrile fibres, and to study the influence they have on concrete physical and mechanical properties.
Mix design of steel fiber reinforced concrete (SFRC) is concerned with achieving a workability, homogeneity, durability and strength suitable for its use. Variables defining any mix design of SFRC are commented below, as well as their influence on some properties of fresh and hardened SFRC. A special attention is paid…
Sandwich-type structures have proved to be alternatives of great success for several fields of application, and specially in the building sector. This is due to their outstanding properties of .specific rigidity and strength against bending loads and other range of advantages like fatigue and impact resistance, attain…
The present paper describes in a general way the most important of the advanced textile technologies which are oriented to the manufacturing of organic matrix composite materials, the paper presents their applications and the possibilities of future development. The use of these advanced weaving techniques allows the…
Various functionalized polythiophene films on electrode surfaces were produced by electropolymerization. Starting from 3-(2-hydroxyethyl)thiophene ( 1 ) different ether and ester derivatives were synthesized: 3-(2-(benzyloxy)ethyl)thiophene ( 2 ), 3-[2-((triphenylmethyl)oxy)ethyl]thiophene ( 3 ), 3-[2-((trimethylsilyl…
Li−LSX (Li−faujasite with Si/Al = 1), cubic at room temperature, is orthorhombic ( Fddd ) at 10 K. In the room-temperature Fd 3̄ phase, Li cations in the supercage are evenly distributed between 2-fold-coordinated sites III and III‘, in close agreement with the cation distribution in Na−X. The cubic−orthorhombic phase…
