Abstract An experimental study on ultrasonic welding of thermoplastic, which is a prelude to study how the technology can be adapted to join composite materials, was conducted. Three sets of specimen were studied to investigate the influence of energy guide on the bonded specimen. No major statistical difference between the ‘energy guides’ of the tested thermoplastic Celuka™ coupons were noted. Failure of the welded specimen was by shear at the interface. A 75% drop in strength for the bonded material was observed.

The paper presents the laboratory experiments and the results obtained regarding the production and characterization of composite materials with coconut fiber for the manufacture of brake pads for small vehicles and medium performances. The experimental research of composite material with organic components determined the influence of some material factors and parameters of the sintering regime on the physico-mechanical characteristics of the tested samples. Knowledge of these characteristics offers the possibility of pertinent appraisals regarding the behaviour of the composite materials intended for used in brake pads applications. Materials with the best features will be selected to determine the functional characteristics of friction and wear.
