You either use Lloyds, BV, or ISO method. So unless you have tons of money to throw around testing materials, there is a way to calculate strength by the use of Formula(s). Then there is the resin to be used like Ortho, Iso, Vynil Ester, and Epoxy. Then there is E glass, S glass, Kevlar, and Carbon. There are three major types of fiber, namely CSM, WR, and Uni. Flexular test is optional as it can be predicted by the formula. So that will be P1,500per x 7times x 3test for one type of fiber. You throw away the result of the highest and lowest. 7 test per specimen is required to arrive at a certain confidence level. Youngs modulus is actually the theoretical straight line projected on the back of the curve. The modulus 3 and 4 can be derived from 1 and 2 if you ask for a graph test instead of just ultimate strength. you need to do 7 test per material with test on, Click to expand.We use to have our material tested by MIRDC in Bicutan, Manila but most independent testing lab that do Standard material testing on steel and concrete should have the equipment.Īlthough relatively cheap at P1,500 per sample laminate.
