Thermal Oxidation of Polypropylene and Modified Polypropylene – Structure Effects
Ageing and stabilization polymers is a major part of materials science. Aging of polymers defined as a set of chemical and physical transformations, leads to the loss of their set the desired properties. The main role in these transformations belong to chemical processes of degradation and crosslinking of macromolecules. Processes decomposition and structuring polymer conjugates include radical...
متن کاملMultiscale Multiphysic Mixed Geomechanical Model for Deformable Porous Media Considering the Effects of Surrounding Area
Porous media of hydro-carbon reservoirs is influenced from several scales. Effective scales of fluid phases and solid phase are different. To reduce calculations in simulating porous hydro-carbon reservoirs, each physical phenomenon should be assisted in the range of its effective scale. The simulating with fine scale in a multiple physics hydro-carbon media exceeds the current computational ca...
متن کاملStructure and Properties of Wood/ Polypropylene Composites
Composite wood products have traditionally relied on thermosetting polymers like phenol-formaldehyde and urea-formaldehyde resins as binders. The continuing need to effectively utilize lignocellulosic fiber from lowquality hardwoods and from recycling streams has prompted consideration of new composites based on thermoplastic polymers [ 1,2]. Much of the development effort has focused on commod...
متن کاملMultiscale damage simulation
Numerous materials show a softening behaviour at dynamic loading. The decrease of stress is caused by the evolution in the microscale in terms of areas where the local stiffness is reduced, e.g. due to micro-void growth. For a numerical treatment of this material behaviour, phenomenological damage approaches are used in daily engineering practice. For a better understanding of the micromechanic...
متن کاملIntegrated multiscale process simulation
We summarize two approaches to integrated multiscale process simulation (IMPS), particularly relevant to integrated circuit (IC) fabrication, in which models for equipment (m) and feature (lm) scales are solved simultaneously. The first approach uses regular grids, and is applied to low-pressure chemical vapor deposition (LPCVD) of silicon dioxide from tetraethoxysilane (TEOS). The second appro...
