Arevo composite additive manufacturing: the future of AFP?
Its multi-axis, continuous fiber technology eliminates tooling, matches strength of titanium parts at 1/3 the weight and cuts part cost vs. hand layup/autoclave cure by a factor of 5.
Read MoreStatistical data pooling in design allowables
In the debate about virtual testing’s role in the design allowables process, one common ground is that it can reduce the number of physical tests required in the traditional building block approach (BBA), in the same that way that data pooling is already used.
