Multilayer paste of carbon fiber reinfroced polymer(CFRP) achieve a better effect for structural strengthening. But more people don't know the lap size of CFRP strengthening.Horse Construction tell you.

1.The lap length of each end should not be less than 200MM. If the number of layers is more than three layers, the lap length should not be less than 300MM..

2.For each side of the non stress direction, the lap length is 100MM.
