“…Taking into account the lower volume fraction of the strengthening fibers/particles and the lower strengthening contribution of particles to the load transfer, the calculated value ~30 MPa seems to be a good approximation of the load transfer real value for the studied composite. Mean residual stresses in the matrix were measured in magnesiumbased MMCs by Farkas et al ex situ [62] and in situ using neutron diffraction [61,63]. They found a higher <σm>max than that of the calculated estimation according to the equation reported in Table 3.…”

Magnesium alloy QE22 (nominal composition 2 wt % Ag, 2 wt % mixture of rare earth elements, balance Mg) was reinforced with 5 vol % Saffil fibers and 15 vol % SiC particles. The hybrid composite was prepared via the squeeze cast technique. The microstructure of the monolithic alloy and composite was analyzed using scanning electron microscopy. Elastic modulus was measured at room temperature and modeled by the Halpin-Tsai-Kardos mathematical model. The strengthening effect of fibers and particles was calculated and compared with the experimentally obtained values. The main strengthening terms were determined. Fracture surfaces were studied via scanning electron microscope. While the fracture of the matrix alloy had a mainly intercrystalline character, the failure of the hybrid composite was transcrystalline.Before the compression tests, the grip heads of the testing machine were lubricated with MoS 2 . For both tensile and compression tests, three samples were used. Mechanical tests were carried out at room temperature (23 ± 2 • C) in a Zwick Z250 PC controlled testing device () with a constant cross head speed of 1 mm·min −1 , giving the strain rate of 5.5 × 10 −4 s −1 (tension) and 1.4 × 10 −3 s −1 (compression). True stress-true plastic strain curves were computed. Characteristic tensile/compression yield stress (TYS/CYS) and ultimate tensile/compression strength (UTS/UCS) were estimated together with the strain-to-fracture, ε f .

“…The commonly used methods to control thermal expansion behaviours of composites are the fiber arrangement control method and the negative expansion particles addition method. The main idea of the fiber arrangement control method is to utilize the negative thermal expansion characteristic of fibers in the axial direction [10][11][12]. Single-ply of fiber reinforced composites can achieve unidirectional zero or negative CTEs by the reasonable design of fiber arrangement.…”

ZrW 2 O 8 -C f /E51 composite with a negative Coefficient of Thermal Expansion (CTE) was fabricated by a method combining mechanical stirring with ultrasonic vibration, then microstructures and properties of the composites were analyzed and summarized by scanning electron microscope (SEM), DIL 402 C thermal expansion tester and electronic universal testing machine. The results showed that particles distribution defects and impregnation defects of carbon fibers would occur when the process parameters were not controlled properly. Long curing time and good fluidity of resin were beneficial for resin impregnating carbon fibers and bubbles overflow. However, for the ZrW 2 O 8 -C f /E51 composites studied in this paper, long curing time and low viscosity could cause particle settling and accumulation. The experimental results confirmed that the CTE (about −0.52×10 −6 /°C) and tensile strength (about 440 MPa) of E51 resin were improved with the addition of carbon fibers and ZrW 2 O 8 particles.
