Rotational molding is a new process for thermosets, few research works have been done on this subject. The goal of this study is to determine the optimal conditions (time, temperature, viscosity, etc) of this process for an epoxy-amine system. The th

Le rotomoulage reactif des resines epoxy/amine met en jeu une cinematique complexe due principalement a la competition entre deux forces: la force de gravite et les forces de dissipation visqueuse. L'ecoulement au cours du rotomoulage est modelise pa

The aim of this study is to evaluate the effect of the humidity on the long term behaviour of glass fiber reinforced thermoplastic in fatigue. Two sets of samples were studied, one set contained 0.2 wt% of water, the second 3.5 wt%. The fatigue tests

Polymeric matrices are viscoelastic materials and dissipate a part of the mechanical energy in the form of heat when they are submitted to a cyclic strain. During a fatigue test, the temperature of the material can increase and stabilize to some exte

Le rotomoulage reactif est un procede prometteur pour les resines epoxy. Il existe peu de travaux sur ce sujet. Le but de cette etude est de determiner les conditions optimales (temps, temperature, viscosite...) pour le rotomoulage. La forme de l'obj

Two types of glass-fibre-reinforced polyester composites have been immersed in water at different temperatures (from 30 to 100°C) and subjected to gravimetric analysis, mechanical tests, and microscopic observations. Three types of damage have been

A special morphology is shown by injected parts of polyester bulk molding compounds (BMC): a skin with thickness 100 nm, is made of polyester–styrene polymer; the fillers and glass fibers are located in the core of the material; the matrix is compo

The solubility parameters of a BMC composite material, its polyester matrix, and its low profile additive [poly(vinyl acetate)] were determined by using several methods. For Hildebrand's solubility parameter : calculation from molar additive laws and
