Oriented Polypropylene

In laboratory conditions, oriented polypropylene composite materials containing various concentrations of anisotropic carbon nanoparticles (nanofibers, nanotubes) were obtained. The change in the mechanical properties of oriented composites is determined. Based on structural studies, it was shown that the increase in strength in oriented composites is associated with the formation of a more perfect supramolecular structure of the polymer matrix due to the introduction of low concentrations of nanofillers.

The using of polymer matrix composite materials has found a wide range of applications in our modern day world. This is as a result of the combination of characteristics which are achieved by these materials. This work aimed on the preparation of polymeric-matrix composite material in order to improve its mechanical properties by using more than one type of reinforcement with different volume fraction values. This composite materials prepared from unsaturated polyester resin as a matrix, reinforced by E-glass fiber with (5%) volume fraction and graphite particles of (1%, 3%, 5%,7% and 10%) volume fractions, and study  the effect of these fillers on the  properties of polyester. The reinforcing by different types of materials with different values of volume fraction led to improve the mechanical properties (i.e. tensile strength, modules of elasticity and hardness) significantly, because of the contribution of both graphite particles and glass fibers to bear the applied load, also due to the high hardness graphite particles

This review examines various studies on reducing tensile stresses generated in a polymer matrix composite without increasing the mass or dimension of the material. The sources of residual stresses and their impacts on the developed composite were identified, and the different techniques used in limiting residual stresses were also discussed. Furthermore, the review elaborates on fibre-prestressing techniques based on elastically (EPPMC) and viscoelastically (VPPMC) prestressed polymer matrix composites, while advantages and limitations associated with EPPMC and VPPMC methods are also explained. The report shows that tensile residual stresses are induced in a polymer matrix composite during production as a result of unequal expansion, moisture absorption and chemical shrinkage; their manifestations have detrimental effects on the mechanical properties of the polymer composite. Both EPPMC and VPPMC have great influence in reducing residual stresses in the polymer matrix and thereby improving the mechanical properties of composite materials. The reports from this study provide some basis for selecting a suitable technique for prestressing as well as measuring residual stresses in composite materials.

Abstract This article has a theoretical and experimental character. It presents the characteristics of two main thermoplastics used in the aerospace industry – poly ether ether ketone (PEEK) and poly phenylene sulphide (PPS). The selected materials are compounds for the production of thermoplastic polymer matrix composites. The paper presents a literature review of the application of thermoplastic polymer matrix composite materials in aviation. Additionally, the paper focuses on the characteristics of carbon fibre-reinforced polymer (CFRP) which plays an important role in the production of aerospace components. Testing methods have been chosen on the basis of the type of composite matrix. The article contains the most important mechanical properties and general characteristics of thermoplastics used as a matrix for CFRP type composites used in the aerospace industry. Individual test procedures which allow for the evaluation of mechanical properties of composite materials on a thermoplastic polymer matrix, have been described. Mechanical tests such as static tensile test and bending of short beams were carried out in order to examine CFRP composites.

Thermoplastic and soluble in organic solvents polyetherimide is of great interest for the creation of heat-resistant composite materials with high physical and mechanical properties. In recent decades, the main scientific approaches to the synthesis of polyimides with the ability to process from melt and solutions in organic solvents have been developed. According to this methodology, the glass transition temperature of rigid-chain polyimides is reduced by increasing the flexibility of the main polymer chain and/or by reducing the intermolecular interaction. Evolution of fine organic synthesis is one of the priority directions of development of chemical technology. Chemistry of high-molecular compounds is the subject of research by various domestic and foreign scientists. This interest is due to the prospects for the use of materials for industrial purposes. The polyetherimide contains various aromatic, heterocyclic and cycloaliphatic groups and systems in its chain. This article describes the main approaches to the creation of polymers with improved, compared with polyimides, technological properties and prospects for their application in the production of filled composite materials based on them. The paper presents the properties of the materials under consideration as a justification for the creation of heat-resistant composite materials.

The influence of the methods of introducing carbon nanoparticles into the epoxy binder and their amount on the complex of physicomechanical characteristics of unidirectional organic and carbon plastics was evaluated. An increase in the breaking load in microplastic made of carbon filaments up to 86% due to the introduction of nanoparticles is shown. An increase in the compressive strength of unidirectional carbon-fiber specimens modified with nanoparticles using a wave machine, up to 32% in comparison with unmodified, has been established.

In a lot of industrial applications the Composite materials have an essential role. The manufacturing of the new composite materials is intended improve the materials applicability. In this work, the influence of silica Nano filler type-and compared that effect with that of silica micro fillers-on mechanical properties of polyester have been investigated. For this purpose, mechanical testing have been used. The addition of Nano  silica and micro silica was in different percentages 1%, 3%, and 5%, due to the fact that Polyester is one of matrix of polymer that is frequently used with strengthening fibers for sophisticated applications of composites because of its resistance to corrosion, cost that is low, smooth coping, and its ability to prevent the outbreak of flame.
