How to improve the compressive strength of waste glass fiber reinforced plastic profiles (such as square tubes) should be started with resin, curing agent, glass fiber or other aspects!
Using reinforced materials of good quality, reinforced materials without alkali glass fiber are used;
Ensure the solidification of glass steel products in a reasonable range, in general, glass fibre reinforced epoxy resin material curing degree if the use of amine curing agent, the best curing degree in the range of 135 degrees --150 degrees, polyester resin, Mohs hardness of about 60 is OK.
Use a high strength resin type;
