In automotive engineering, the main load bearing structure (Body-in-White, BIW) has traditionally been manufactured using metals such as steel and light alloys. In order to satisfy upcoming European regulations on CO2 emissions, considerable weight reducti ...
PROBLEM TO BE SOLVED: To provide a resin microchip having a microchannel having a transparent flow passage of low absorption in an ultraviolet area sealed with a fine upper substrate of excellent surface smoothness and high dimensional precision. ;SOLUTION ...
Bone is a natural cellular composite, with a gradient structure going from a loose interconnected core to an outer dense wall, thus minimising bone weight while maintaining a high mechanical performance. Bone can be repaired using either auto- or allo- gra ...
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 ...
In this paper, the chemorheological and dynamic mechanical behavior of melamine-formaldehyde (MF) resins of four different formaldehyde/melamine (F/M) molar ratios (1.25, 1.5 1.75 and 2.00) are investigated. MF resins polymerize via a polycondensation reac ...
The influence of the primary molecular parameters chain configuration, architecture and molecular weight (MW) on the mode of mechanical breakdown is discussed for two series of (amorphous) thermoplastic polymers, methyl methacrylate glutarimide copolymers ...
In the present study, the optimal medium perfusion rate to be used for the continuous culture of a recombinant CHO cell line in a packed-bed bioreactor made of Fibra-Cel disk carriers was detd. A first-generation process had originally been designed with a ...
An overview is presented of current research at EPFL on structural metallic materials produced by infiltration processing. The paper comprises a brief introduction to the infiltration process, then presents results on particle reinforced metals and open-ce ...
The bioconversion of L-phenylalanine to 2-phenylethanol by Saccharomyces cerevisiae in fed-batch expts. has shown that concns. of 2-phenylethanol of >2.9 g/L have a neg. impact on the oxidative capacity of the yeast. Without tight control on ethanol prodn. ...
A moulding process, in particular a bladder inflation moulding process for the production of a composite material based part, said composite material comprising a polymer matrix and reinforcing fibres, wherein at least a portion of external surface of said ...
