Melting of thermoplastic plastics with iIF-laser radiation
Abstract
The melting of thermoplastic plastics with and without fibre reinforcement is investigated during the influence of Nd:YAG and CO sub 2 laser radiation. Absorption measurements as a function of temperature are presented. By means of a model of heat conduction with a term of a source corresponding to the optical penetration depth and at a given surface temperature, penetration depths are evaluated and compared to the processing parameters of the experiments. On the basis of these results, possible technical applications concerning the welding of thermoplastic plastics and winding of fibre-reinforced thermoplasts (filament winding) is discussed.
