Assessment of manufacturability of materials used in production and repair of machines that are resistant to prolonged exposure to corrosive environments

REPAIR RECONDITIONING MODERNIZATION (2022)

N. Yu. Bulanaeva—Klimova T. A. Guzeva G. V. Malysheva

The assessment methodology for manufacturability of fiberglass parts in conditions of small-scale and repair production is given. Materials based on epoxy binders, the curing of which takes place at elevated temperature, were used as objects of the investigation. To compare manufacturability of various molding processes, composites based on dispersed fillers and thermoplastic matrices are also considered. The results of expert assessments of manufacturability are presented, which show that molding processes consisting of similar technological operations in terms of content, differ significantly in cost and material intensity.

Optimization of the rheological properties of epoxy resins for glass and carbon reinforced plastics

IOP Conference Series Materials Science and Engineering (2016)

Pyi Phyo Maung G. V. Malysheva I. K. Romanova

Vacuum assisted resin transfer moulding (VARTM) offers advantages such as simplicity, low cost of consumables, and the ability to carry out the impregnation process and curing without using expensive equipment and tooling. In the VARTM process, rheological properties of resin have a critical impact on the impregnation and curing process. In this article, the experimental results of viscosity are presented, including the glass transition temperature, and the tensile and bending strength of the epoxy binders with the amine hardener, which depend on the quantity of its active solvent composition. The active solvent used is diethylene glycol. It shows that for an increase in the content of the active solvent, a reduction in the viscosity and a reduction of the glass transition temperature and strength occurs. The optimum composition of the binder is selected by using the Pareto optimization criteria and the Cayley - Smorodinskaya method. By using the epoxy binder, the active solvent should not exceed 10-15% by weight. This approach helps to optimize the amount of active solvent added to the epoxy resins for the criterion of viscosity, strength, and heat resistance.

Predicting the endurance of heterogeneous epoxy resin

Materials Research Innovations (2015)

Guoqiang Zhong L. H. Liu G. V. Malysheva Xiao Ouyang

This paper presents the results of mechanical test and no-failure time for glass- and carbon-reinforced plastic with heterogeneous epoxy resin. Heterogeneous matrix consists of an epoxy resin and polysulfone. The optimum ratio of polysulfone has been determined. For reliable calculation, parametric model is used. The values of bending strength and impact strength are used as output parameters. The output of the heterogeneous matrix depends on the degradation speed and this method is used for determining the degradation speed. Model changes in the technical state and examples of calculation of the endurance (resource of resin) are given.
