Effect of different chemical solution on tensile strength of polymer composite

الملخص EN

Hand lay- up technique was used to prepare sheets of epoxy composites reinforced with woven roven (0°-90°) glass fiber in weight fraction (50%) .The sheets were left to solidify at room temperature (23± 2) C°.

The samples immersed in (HCL, KOH, distilled water, Benzene, and Kerosene) for equal time at constant temperature (23± 2) C°.

The tensile strength was calculated for the samples before and after immersion in different chemical solutions.

The result shown that the tensile strength of the samples decreased after immersion in different solutions, while (Kerosene) solution has maximum effect in decreasing the tensile strength of the sample, the (Benzene) solution has minimum effect in decreasing the tensile strength of the sample, and the other solutions (distilled water, HCL, KOH) located between them in different ratio.

Finally the samples immersed in (HCL) solution has maximum relative mass (minimum absorption resistance) while the sample immersed in distilled water has minimum relative mass (maximum absorption resistance) .
