| Summary: | One of the defining features of a new material is to be resistant, easy to process, to combine the
qualities of basic materials, in the current technique, but not to borrow from them their negative properties. In
recent years, carbon fiber composites have been increasingly used in different ways in reinforcing structural
elements. Its use in industry can be either for retrofitting to strengthen an existing structure or as an
alternative reinforcing (or pre-stressing) material instead of steel from the outset of a project. Retrofitting has
become the increasingly dominant use of the material in civil engineering, and applications include increasing
the load capacity of old structures (such as bridges) that were designed to tolerate far lower service loads than
they are experiencing today, seismic retrofitting, and repair of damaged structures. Retrofitting is popular in
many instances as the cost of replacing the deficient structure can greatly exceed its strengthening using
CFRP. Specifically, the use of composite materials as a reinforcement for wood beams under bending loads
requires paying attention to several aspects of the problem such as the number of the composite layers applied
on the wood beams. |
