Design of compositions and types of structures of injection molded dispersed filled thermoplastics with good processability and high strength
The issues on the assessment of rheological properties of dispersed filled polymer composite materials (DFPCM) in terms of generalized parameters of disperse structure are considered. The dependences of pressure loss during injection molding of thin-walled DFPСM products with different types of disperse structure: dilute, low-filled, medium-filled and high-filled systems are given for the first time. It has been established that to obtain DFPCM based on thermoplastics with good processing properties and products with high strength, it is necessary to create materials having medium-filled type of structure and the generalized parameter Θ ≈ 0.5-0.6 vol/vol. The algorithm for calculating the dispersed filler content with known basic properties to provide a given type of DFPCM structure is proposed.
