As widely known, glass fiber reinforced plastics have very great value of strength weight ratio and many other excellent properties, being heat and water proof and having electric resistance among others. Hence glass fiber reinforced plastics are attracting the attention of the engineering world. The investigation about the strength of glass reinforced plastics is performed by many researchers from different standpoints, the summarizing consideration there of being required by many engineers. The present paper proposes to give such summarizing considerations about the strength of glass fiber reinforced plastics to meet the above mentioned requirement.
