Train Windshield Composite Part Featuring Low Weight and High Strength

Traditional metal wiper arms are heavy with prominent rotational inertia, prone to fatigue cracks at welding joints and chemical corrosion from deicing liquids. They produce severe flutter under high-speed airflow and impose heavy impact loads on wiper transmission parts. This monolithic carbon fiber wiper arm adopts variable cross-section fiber stacking and aerodynamic modeling. It features low inertia, uniform stress distribution, chemical erosion resistance and coordinated thermal deformation

Yes. The asymmetric variable cross-section fiber layup fits the actual force path of the wiper arm. It withstands instantaneous centrifugal torsion during reciprocating wiping, prevents blade offset and streak marks, and keeps stable and uniform wiping precision at all train speeds.

Its ultra-low mass greatly reduces rotational inertia when the wiper starts and stops. It relieves sudden impact on gears and connecting linkages, slows component abrasion, and cuts the frequency of maintenance and replacement for the wiper drive system.
