3D modeling of samples for testing the mechanical properties of PA Carbon Fiber material

Abstract

U ovom završnom radu se provodi statičko vlačno ispitivanje na 3D modeliranim ispisanim ispitni uzorakma koje su oblikovane prema standardu ISO 527-2. Ispitni uzorci su proizvedeni pomoću MakerBot Method pisača iz različitih materijala, uključujući PA carbon fiber materijala. Filament je tanka nit materijala, najčešće plastike, koja se koristi kao sirovina u 3D ispisu. Cilj istraživanja je bio analizirati utjecaj različitih materijala i postavki ispisa na mehanička svojstva uzoraka, s posebnim naglaskom na rasteznu čvrstoću i modul elastičnosti. Statičko vlačno ispitivanje provedeno je korištenjem kidalice Inspekt Blue 20, koja omogućava precizno mjerenje sila potrebnih za rastezanje ispitni uzorak do njihovog loma. Rezultati ispitivanja pružili su usporedbu mehaničkih svojstava uzoraka izrađenih različitim materijalima, što omogućuje detaljan uvid u njihovu čvrstoću i otpornost na deformacije. Zaključak istraživanja naglašava značajan utjecaj vrste materijala i parametara 3D ispisa na mehaničke karakteristike ispitivanih ispitnih uzoraka, što je od posebne važnosti za industrijsku primjenu 3D ispisanih dijelova.In this final work, static tensile testing is performed on 3D modeled printed test specimens that are shaped according to the ISO 527-2 standard. Specimens were manufactured using a MakerBot Method printer from various materials, including PA carbon fiber material. Filament is a thin thread of material, most often plastic, that is used as a raw material in 3D printing. The aim of the research was to analyze the influence of different materials and printing settings on the mechanical properties of the specimens, with a special emphasis on tensile strength and elastic modulus. Static tensile testing was performed using the Inspekt Blue 20 tensile tester, which allows precise measurement of the forces required to stretch the test specimens until they break. The test results provided a comparison of the mechanical properties of specimens made of different materials, which provides a detailed insight into their strength and resistance to deformation. The conclusion of the research emphasizes the significant influence of the type of material and 3D printing parameters on the mechanical characteristics of the tested specimens, which is of particular importance for the industrial application of 3D printed parts
