Izrada termoplastičnih kompozitnih cevi metodom namotavanja, I : opis eksperimenta / Fabrication of Thermoplastic Composite Pipes Using Tape Winding Process, I : Experimental Procedure
(Društvo inženjera plastičara i gumara, 2005)
Odlučujući faktor prilikom zamene konvencionalnih materijala sa kompozitima su troškovi. Dok cena sirovih materijala obično opada sa porastom potražnje, kod kompozita je potrebno smanjiti troškove proizvodnje automatizovanim ...
Prediction for debonding damage process of glass beads-reinforced modified polyphenylene oxide under simple shear
(Elsevier Science Sa, Lausanne, 2005)
A three-dimensional finite element cell modeling technique has been applied to predict the particle-matrix debonding process of particulate polymer composite (PPC) subject to simple shear loading. The particle-matrix ...
Structural changes in the fabrication and ageing of PA66 textured yarn
(Wiley-VCH Verlag Gmbh, Weinheim, 2005)
The characterization of textured yarn is of great significance for both producers and final users. The influence of the texturing parameters (draw ratio and heater temperature) on the characteristics of the textured polyamide ...
Influence of the electrode parameters on pulse shape characteristic of gas-filled surge arresters at small pressure and inter-electrode gap values
