Derivatization of Glass and Polypropylene Surfaces

Static and fatigue behaviour of glass-®bre-reinforced polypropylene composites

This paper is concerned with fatigue of polypropylene/glass-®bre thermoplastic composites produced from a bidirectional woven cloth mixture of E glass ®bres and polypropylene ®bres. The latter becomes the matrix after the application of heat and pressure. This composite was manufactured with a ®bre volume fraction Vf of 0.338. The e€ect of layer design on the static and fatigue performance was ...

Modifiers for Glass Fiber-reinforced Polypropylene and Polyamide

influence of maleic-anhydride-polypropylene (mapp) on wettability of polypropylene/wood flour/glass fiber hybrid composites

the influence of maleic anhydride-polypropylene (mapp) (0, 2, 3 and 5%) as a compatibilizer on the wettability of polypropylene/wood flour/glass fiber hybrid composites was studied by using the contact angle determination technique. sample slats with a cross section of 10×70 mm were made by a twin screw extruder. specimens were conditioned at room temperature and the angles between the water dr...

Glass Fiber Reinforced Polypropylene Mechanical Properties Enhancement by Adhesion Improvement

Glass fibers (GF) are the reinforcement agent most used in polypropylene (PP) based composites, as they have good balance between properties and costs. However, their final properties are mainly determined by the strength and stability of the polymer-fiber interphase. Fibers do not act as an effective reinforcing material when the adhesion is weak. Also, the adhesion between phases can be easil...

Micromechanical Parameters from Macromechanical Measurements on Glass Reinforced Polypropylene

In recent years many elegant techniques have been developed for the quantification of composite micromechanical parameters. Unfortunately most of these techniques have found little enthusiastic support in the industrial product development environment. We have developed an improved method for obtaining the micromechanical parameters, interfacial shear strength, fibre orientation factor, and fib...
