Surface roughness of resin transfer moulding
WebFeb 28, 2024 · For both materials, the degree of slip phenomenon decreases when the surface roughness increases. The experimental results of PF6680 show this with the surface roughness of Ra 1 and Ra 2, as the location of the white stripes is exactly the same before and after injection molding. This means there is no slip of the white stripes.
