| 要約: | Surface energy has a significant impact on the adhesion
and friction behaviour of fibres in composite materials.
Finding the surface energy of a single fibre, on the other
hand, maybe challenging. In this work, the surface energy
of single aramid fibre is calculated using dynamic contact
angle measurements. The contact angles of three different
types of Twaron® aramid fibres with varying treated
materials and thicknesses are tested in a series of test
liquids. As a result of the changing surface characteristics
of the fibre, the surface energy of treated fibre is found to
be approximately 37% greater than that of untreated
fibre. The thickness of the fibre also affects its surface
energy because thicker fibres have a larger contact area,
which increases surface energy in the region of contact. At
specific applied normal load conditions, it can be found
that the coefficient of friction increased as the total surface
energy in the area of the contact interface increased. |
