Rezumat: Lucrarea prezinta o parte din rezultatele experimentale si cele predic ionate, utilizand conceptele micromecanicii, ob inute si vizate pentru una dintre proprietat ile de material importante in ceea ce prives te dezvoltarea de materiale i structuri destinate sistemelor de incalzire – coeficientul liniar de dilatare termica. Materialele compozite hibride analizate si investigate au fost elaborate utilizand un concept si o tehnologie proprie s i sunt de tipul particula fibre armate intr-o matrice de material polimeric. Analiza se efectueaza din punct de vedere al influen ei constituen ilor asupra acestei propriet? i de material, abordandu-se aspecte cu privire a morfologia structurilor, procentul de armare cu incluziuni s i regimul termic aplicat

Abstract: The paper aims to present sequences from a DOE conducted approach on a selfdeveloped and manufactured multiphase particle-fiber type polymeric composite materials with the purpose of using as alternative materials for heating system configurations. The herein approach will focus on the modelling issues and experimental research done with respect to one of the major influecing factors in engineering materials design from thermal point of view , namely the coefficient of thermal expansion (i.e. CTE). The latter is responsible for the dimensional stability of any mechanical structures and is becoming lower and constanly over a large temperature range by controlling the materials’ constitutives and individual properties.
