THE SPECIFIC PROPERTIES OF POLYESTER LAMINATES

Tema ovog rada je„Specifična svojstva poliesterskih laminata“. U nastavku rada obraditi će se vrste kompozita, kao i matrice, ojačala, punila i dodaci pri izradi poliesterskih laminata. Kao dodatak obavljen je i eksperimentalni dio uz analizu rezultata te zaključak eksperimenta. Kompozitni laminati su kompoziti na bazi nezasićene poliesterske smole ojačane staklenim vlaknima. Primjena staklenih vlakana kao ojačanja omogućuje proizvodnju kompozita koji imaju veliku specifičnu čvrstoću. Ti su laminati čvrsti i kruti. Mijenjanjem broja i rasporeda ojačala može se djelovati na njihova mehanička svojstva. Zbog svojih dobrih mehaničkih i fizikalnih svojstava, kompoziti imajuvrlo raširenu primjenu.The title of this paper is "The specific properties of polyester laminates" from the case of tehnical materials. In continuation of the paper I will explain types of composite materials, as well as the bases, reinforcements, aditives and fillers use din fabrication of composites. In addition, experimental work was done including analysis of the result and the conclusion oft he experiment.Composite laminates are composites on the base of the unsaturated polyester resin, reinforcered with glass fibers. Use of the glass fibers as reinforcementsmakes shore the fabrication of compositeswithhuge specific firmness. This kind of laminates are stiff and firm. With the change of number and placement of the reinforcement, we can affect on mechanicproperties. Becouse of it's fine mechanical and fisicalproperties, composites have wide specter of use
