Fatigue behavior of PLA-wood composite manufactured by fused filament fabrication

In this paper, the fatigue behavior of a polylactic acid-based composite reinforced with wood (trademarked as Timberfill) processed through fused filament fabrication is analyzed through rotating bending fatigue tests. Originally, this material was developed with the aim of enhancing the resistance...
