The correlation between sizing formulation, bundle mechanical characteristics, and bundle-matrix static and dynamic interactions are investigated. Two glass-fiber sizing formulations are considered, one containing polyvinyl acetate (PVAc) and the other pol ...
The high-temperature wettability of alumina particulate preforms by copper is investigated by means of infiltration experiments conducted at 1473 K under low oxygen partial pressure. Wetting is quantified in terms of drainage curves, which plot the volume ...
Microfluidic systems with incorporated microelectrodes are adopted in a variety of applications in life sciences. However, most of micro-electro-fluidic devices are fabricated based on silicon and silicon related materials micromachining processes, which a ...
The non-isothermal flow during compression molding of thermoplastic-based composites having a planar, randomly oriented fiber structure has been investigated. Local interactions at the bundle-bundle level were measured and a constitutive equation was deriv ...
The reinforcement potential of pulp fibres is presently not fully explored in thermoplastic composites. One of the reasons is that currently used processing methods comprise several severe thermomechanical steps inducing premature degradation of the fibres ...
High-pressure injection molding (nominal pressure 500 MPa) is known to substantially improve the mechanical properties of high-density polyethylene of a high molecular weight (HMWPE). This work shows that if the mold is equipped with an exit cavity, the te ...
In injection-moulded parts, the degree of orientation (anisotropy) varies over the cross-section. Normally, such parts exhibit a layered structure, with a biaxially oriented surface layer (stretching of the flow front during mould filling), a highly orient ...
This paper presents the concept of a standard method used to determine the durability of injection molds. In particular, some Rapid Tooling molds are less resistant to abrasive plastics than conventional steel molds. Some evidence of wear in a conventional ...

A set of new technologies to fabricate microchannels using photosensitive polymer materials is presented. They are based on the use of polymers, hereafter called photopolymers, that are cured with UV light under a mask exposure. The basic material is ail e ...
