All three sources of variation are highly significant: fiber type (F = 81.231, p < 0.001), concentration (F = 182.223, p < 0.001), and their interaction (F = 10.111, p < 0.001).

approached but did not reach significancep = 0.065so close (0.05 < p ≤ 0.1)

While this sample size is sufficient for the detection of the large main effects observed (concentration effects consistently reached p < 0.001), the type × concentration interaction under tensile loading approached but did not reach significance ( p = 0.065), and a study with larger replication might resolve this borderline result.
