ThermodurcissablesIndex. décimale : 668.4 Plastiques, vinyles Résumé : Polymer matrix composites are finding increasing number of applications due to their high weight-saving potential as well as unique characteristics, such as high strength-to-density ratio, fatigue resistance, high damping factor, and freedom from corrosion. While many textbooks are available on the mechanics of polymer matrix composites, few cover their processing. Processing of Polymer Matrix Composites fills this gap. The book focuses on the major manufacturing processes used for polymer matrix composites and describes process details, process parameters and their effects on properties and process-induced defects, and analytical and experimental methods used for understanding process conditions. The book describes fibers, thermosetting and thermoplastic polymers, and interface characteristics that are important from the standpoint of both design and processing. It also emphasizes the applications of process fundamentals for both continuous fiber and short fiber polymer matrix composites. In addition the book considers quality inspection methods, tooling, and manufacturing costs and environmental and safety issues. Note de contenu : 1. INTRODUCTION : 1. Constituents – 2.

StratifiésIndex. décimale : 668.4 Plastiques, vinyles Résumé : A thermoplastic composite sheet based on TPU film reinforced with continuous carbon fibers has been developed for lightweight load-bearing structures. The orientation of the fiber plies in the thermoplastic composite sheet can be varied from unidirectional to multiaxial, and adapted to the load case. Economical and robust components can be fabricated using a laminate structure consisting of two thin outer layers of TPU composite sheet and a core of continuous glass fiber-reinforced polyamide 6. Note de contenu : - Fiber-film-tape unit process
- Low melt temperature, low viscosity
- Anisotropic to quasi-isotropic properties
- Stiffer and stronger than PA6 composite sheet

Moulage par transfert de résine sous videIndex. décimale : 668.4 Plastiques, vinyles Résumé : The trend toward electromobility only reinforced it : lightweight engineering has long been the focus of the automotive industry. Lightweight engineering has two positive effects on the sustainability of vehicles. A lighter vehicle consumes less energy for acceleration and frictional resistance. Moreover, fewer raw materials are needed for production which is another positive contribution toward sustainable mobility. Note de contenu : - Weight reduction with composite sandwich structures
- Weight and cost savings
- Established and cost-effective in large, global markets
- Example applications in series vehicles
- Sandwich manufacturing process
- The challenge of HP-RTM
- Short injection times allow the use of cost-effective rigid foams
- Process control based on the foam core's compressibility
- Optimum resin choice
- Successful test series
- Composite sandwiches are mature enough to significantly reduce a car's weight
- Fig. 1 : Different fibre reinforcements : oriented continuous fibres (tissue/scrim, UD) provide excellent mechanical properties (press process manufacturing
- Fig. 2 : Sandwich construction increases rigidity/stiffness at the same weight
- Fig. 3 : Increased core density over 0.1 kg/dm^3 hardly offers additional stiffness advantages
- Fig. 4 : With comparable stiffness and rigidity, the sandwich is much lighter, thus requiring fewer expensive raw materials. Thickness (height) is higher in the sandwich

ThermoplastiquesUne matière thermoplastique désigne une matière qui se ramollit (parfois on observe une fusion franche) d'une façon répétée lorsqu'elle est chauffée au-dessus d'une certaine température, mais qui, au-dessous, redevient dure. Une telle matière conservera donc toujours de manière réversible sa thermoplasticité initiale. Cette qualité rend le matériau thermoplastique potentiellement recyclable (après broyage). Cela implique que la matière ramollie ne soit pas thermiquement dégradée et que les contraintes mécaniques de cisaillement introduites par un procédé de mise en forme ne modifient pas la structure moléculaire.Index. décimale : 668.4 Plastiques, vinyles Résumé : Thermoplastic resin transfer molding (T-RTM). The T-RTM process has been successfully applied as a B-pillar reinforcement made from a continuous fiber-reinforced plastic, utilizing a low-viscosity caprolactam system. This was done in cooperation among the company research team at Volkswagen AG, BASF SE and Krauss-Maffei Technologies. This production variant borrows from current RTM processing technologies and can be used to produce thermoplastic FRP parts for automotive applications economically.

Scanning electron micrographs (SEMs) of consolidated layups (cross-laminate) with low and high pore content. The pores here are identifiable from the black and white areas - 3. Radiation-induced vacuum consolidation (RVC) protects the material against thermo-oxydative degradation - 4. An organosilicon coating on the old surface makes it possible to consolidate a tape layup without using any release agents at all - 5. Comparison of the bending stiffnes and bending strength achieved with RVC and a reference process reveals a far superior performance of the layup consolidated with RVC - 6.
