“…The Regardless of frequency used in tests presented in this work, Figure 12.a shows that the studied composite presents a HCFS that is higher than those obtained for UHMWPE or Nylon 66 for the same stress level range. The studied composite presents a 22.44 MPa HCFS, which is 69.87% higher than the value obtained for UHMWPE [58]. For Nylon 66, in [59], specimens broke before reaching the maximum number of cycles at a 14 MPa stress level, which was the lower stress level in their tests.…”

A new natural fiber composite made of high density polyethylene (HDPE) and short birch fibers (SBF) was developed to replace high-performance thermoplastics (Polyamide) commonly used in gears manufacturing.3-point flexural quasi-static tests were achieved on bending specimens to assess mechanical properties.Comparison between these results and those of polyamide (PA) and neat polyethylene has showed that the polyethylene reinforced with 40%wt of SBF presents tensile and flexural mechanical properties that are higher than those of the PA11 or the neat polyethylene. After static characterisation, fatigue tests were performed to determine ε-N curves and the evolution of residual strength. Then, the fatigue behavior of the studied composite has been compared with that of PA66 and of ultra-high molecular weight polyethylene (UHMWPE). It has been noticed that polyethylene reinforced with 40%wt of SBF presents a high cycle fatigue strength (HCFS) that is more important than that of PA66 and UHMWPE. Consequently, the studied composite represents a good alternative to replace Nylon in spur gears manufacturing.
