The average elongation of the samples had a considerable deviation, with 25%PBT/75%PA6 reaching the maximum value of 37.92% and the 75%PBT/25%PA6 sample getting a nominal value of 0.94%. Besides, when mixing GF fiberglass into a PBT/PA6 blend with a 0 and 3% GF ratio, the tensile strength changes and decreases instability. But at 6% GF, there is a clear improvement as tensile strength gradually increases at all PBT/PA6 ratios. Therefore, to obtain an excellent tensile strength value, the GF content in the mixture should be more significant than 6% by weight of the blend.
