Will the FRP section crack for a long time?
Under normal circumstances, glass fiber reinforced plastic profiles will not appear cracking phenomenon, if there is cracking phenomenon, may be the following reasons:1, the placement method is incorrect, such as irregular, non closed section of a large number of stacked2 、 the resin content in the profile is low, filling is more (see if the section color is whiter, and more powder fall off at the same time)
As long as the design of the structure is reasonable and the quality of the product conforms to the design requirements, the normal use shall not be cracked.
It will be。Glass steel cracking has the following factors:1, in production, the ingredients are too high, curing reaction is fierce.2, in production, the product is too thick, no sub operation, resulting in thermal cracking.3, the product stiffness is not enough, deformation is too large and cracks.4, the strength of the product is not enough, the use of excessive force due to cracks.5, surface gel will produce cracks due to thermal contraction.
