Modeling of Polymer Composite Materials Chaotically Reinforced with Spherical and Cylindrical Inclusions

Abstract

The technical and economic efficiency of new PCMs depends on the ability to predict their performance. The problem of predicting the properties of PCMs can be solved by computer simulation by the finite element method. In this work, an experimental determination of the physical and mechanical properties of PTFE PCMs depending on the concentration of fibrous and dispersed filler was carried out. A finite element model in ANSYS APDL was built to simulate the strength and load-bearing capacity of the material with the analysis of damage accumulation. Verification of the developed computer model to predict the mechanical properties of composite materials was performed by comparing the results obtained during field and model experiments. It was found that the finite element model predicts the strength of chaotically reinforced spherical inclusions of composite materials. This is due to the smoothness of the filler surfaces and the lack of filler dissection in the model. Instead, the prediction of the strength of a finite element model of chaotically reinforced cylindrical inclusions of composite materials requires additional analysis. The matrix and the fibrous filler obviously have stress concentrators and are both subject to the difficulties of creating a reliable structural model.

Study on the Impact of a Combination of Synthetic Wollastonite and 2-Mercaptobenzothiazole-Based Fillers on UHMWPE Polymeric Matrix

“…The composition materials using this method are characterized by a significant improvement in wear resistance and deformation-strength properties. In addition, one of the common ways of dispersing fillers is the use of mechanical activation in a planetary mill, which is due to the simplicity and universality of the method [48][49][50][51]. Also, there are alternative ways of dispersing agglomerates using laser treatment [52] and additional modification of nanoparticles by adhesion promoters and surfactants [20,[53][54][55].…”

“…The physico-mechanical properties of the composite material based on polytetrafluoroethylene are influenced by the parameters of carbon fiber distribution [22], technological parameters [23], the content of the components of the composite material [24,25].…”

Study of Physical Properties of Biocomposite Based on the Polymer Blends Used for Denture Base Applications

“…Polymeric-based material is often used to manufacture dentures [6,7]. Due to their unique properties, polymeric materials are an important component of dentistry since they may be used for various medical purposes that are impossible with other materials [8,9]. Acrylic resin is the most frequently employed polymer in biomedical and dental applications, especially as denture base materials [10,11].…”
