  • 6 Advantages and 6 disadvantages of composite Decking. The use of composite decking really seems to be taking off here. While at the Calgary Home and Garden Show I had a bit of a chat at a decking booth. He told me that composite decking material is becoming more and more common. They are still building more timber/wood decks than composite decks, but composite decks are becoming more popular and common. Below are a few advantages that they talked about with& ...


  • Nonmetallic Aircraft materials Part Two (Advantages/disadvantages and Safety of composite materials). in Aircraft materials Processes and Hardware. In the 1940s, the aircraft industry began to develop synthetic fibers to enhance aircraft design. Since that time, composite materials have been used more and more. When composites are mentioned, most people think of only fiberglass, or maybe graphite or aramids (Kevlar). composites began in aviation, but now are being& ...


  • While composite fillings work well, there are some disadvantages. First, the procedure takes longer to do than a traditional silver filling because there are more steps. Second, the fee is generally higher than for a silver filling. Third, teeth with composite restorations are not as resistant to decay as silver fillings. Fourth, composite fillings will stain and discolor over time. Finally, the composite material does not work well in areas of the mouth where it is difficult to keep the tooth dry such as& ...


  • Reinforced concrete is a g~od example of a composite material. The steel and concrete retain their individual identities in the fmished structure. However, because they work together, the steel carries the ~nsion loads and the concn;te carries the compression loads. Although not covered by this bpok, metal and ceramic qmtrix composites are being studied intensively. composites in structural applications have the following characteristics: 1.3 Advantages and disadvantages of& ...

  • The ability to tailor the basic material properties of a Laminate has allowed new approaches to the design of aeroelastic flight structures. Hot curing is necessary in many cases requiring special tooling. Difficult to attach.2 Limitations of composites Some of the associated disadvantages of advanced composites are as follows: High cost ofmaterials and fabrication. but also into common implements and equipment such as a graphite racquet that has inherent damping. for the& ...
