After Consideration Of The Durability Of Composite Repair

Composites can be durable long after the repair? The answer can be said that a few decades, but this requires appropriate protection measures, such as glass fiber material after the repair had a record 50 years of use, of course, this is also the case in the face of environmental erosion was sufficient protection to achieve results, these erosion from the environment include: ◆ high temperature (infrared radiation) and ultraviolet (UV) radiation can erode a resin and fiber ◆ humid environment, if fibers are not sealed well in advance properties of coated mold or not full will the best measure eroded ◆ gasoline fuel, hydraulic fluid, antifreeze, acids, coatings and chemical bleaching agents or other solvents to resist erosion from the high temperatures and UV radiation is to use a UV inhibitor to repair the surface appropriate protective coating , bright color surface layer thus formed is enough to reflect infrared radiation. A study conducted in the 1970s showed that the black coating of the composite material surface temperature can be higher than 115 ° F to 120 ° F (ie, 29 ℃ to 35 ℃) than the surrounding air temperature. Repair exhaust pipes or other hot parts of the region must also be close to a high temperature specialty resins and adhesives. When current corrosion also need to be considered, such as direct contact with the aluminum layer of carbon fibers exhibit rapid aging, in particular bolted repair
