A liquid droplet measurement technique as a means of assessing the interlaminar shear strength of fibre-reinforced composites

摘要: Abstract A liquid droplet measurement technique was used to measure the contact angle for low modulus, medium modulus and high pitch-based carbon fibres. phase transfer catalytic oxidation treatment an electrochemical both resulted in falls observed glycerol angle. Increases surface energy values were estimated using equation-of-state approach. The increased concentration of oxygen- nitrogen-bearing groups on fibre (as shown by Auger electron spectroscopy), resulting a fall technique, corresponding improvements composite interlaminar shear strength ( ilss ) observed. Thus it that determined this method could be assess changes due fibre, provided only chemical from treatment.
