As the range of applications for fiber-reinforced polymer (FRP) composite materials in civil engineering constantly increases, there is more and more concern with regard to their performance in critical environments. The fire behavior of composite material ...
The behaviour of brittle matrix fibre reinforced-composites is dependent of the properties of its constituents (fibre, matrix and fibre-matrix interface) and is affected by the mechanical and environmental loads. The fracture of a unidirectional composite ...
The present work aims to enhance the interlaminar toughness of carbon/epoxy composites produced by RTM by modifying the resin with hyperbranched polymers (HBPs). A HBP content of 7.5% in the resin was selected as the best compromise between a slight loss i ...
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 ...
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 ...
The stress transfer from broken to unbroken fibers in fiber-reinforced polymer-matrix (PMC) and aluminum-matrix (AMC) composites is studied using a detailed 3D finite element model (FEM) and using the standard shear-lag model (SLM). The stress transfer pre ...
Dendritic hyperbranched polymers have been shown to be able to double the interlaminar fracture resistance of epoxy-based composites and to reduce the internal stress level by as much as 80% with only 10 phr of modifier. These property improvements were ob ...
New thermoplastic composites with their composition tailored at the yarn level were proposed and successfully prepared. A specific processing method was developed for composites exhibiting different fibre and porosity concentration gradients. Mechanical pr ...
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. ...
Temperature-dependent material properties of glass fiber-reinforced polymer composites were derived from tests performed on the material itself, from references concerned with similar polymer materials and from observations during full-scale fire experimen ...
