Abstract
A process for manufacturing a base board of a high-speed rail equipment cabin using a composite material is disclosed. The composite material includes: aramid honeycomb, PET foam, 3K twill carbon fiber flame retardant prepreg, unidirectional carbon fiber flame retardant prepreg, glass fiber flame retardant prepreg, aramid flame retardant prepreg, and 300 g/cm2 single component medium temperature curing blue epoxy adhesive. The process includes manufacturing a base-board main plate (1), a base-board handle (2) and two base-board sliders (3). While installation, the base-board handle (2) is stuck to one side of the base-board main plate (1), and the two base-board sliders (3) are respectively stuck to another two opposite sides of the base-board main plate (1). The weight of the base board made from the composite material is 35%-40% lower than the base board made from the aluminum alloy material, which leads to a good prospect of application.
