Abstract. Vacuum Assisted Resin Infusion (VARI) method employs a mould on top of which number fabric pieces are laid up and impregnated by resin drawn through vacuum. Simulation VARI depends the determination permeability. In this work, permeability value is selected from set discrete values genetic algorithm. An impregnation simulation model run ComsolTM to compute flow front propagation insid...

nowadays, food industries by- product is one of the best choice for functional and novel food products. bitter compound is the main problem to use lemon juice by-product.in this study, press peel and clarifier pulp residues were used to produce marmalade and drink.the vacuum method was proved to be the best debittering process.this pulp contains considerable amount of pectin and acid which appr...

Abstract Repair and maintenance operations of wind turbines constitute a significant part costs energy. In this paper, technologies structural repair damaged turbine blades are reviewed. Costs repair, technological contribution to the discussed. Technologies compared, including hand layup lamination, vacuum with infusion, ultraviolet curing high temperature thermal systems. Computational models...

A neural network modelling technique and its training to diagnose polymer composite materials based on tomography data is introduced. As an object of study, carbon fiber made by vacuum infusion technology using epoxy binder considered. X-ray microtomography was used analyze structure the provided images were as a database for creating network. developed, including algorithm converting tomograph...
