“…As a result, one the one hand, the reinforcing effect of the fibers is countervailed and, on the other hand, reduction in strain at break is induced. (Arencon & Velasco 2009) and σ M = 36.1 MPa (this work)} is in the order of the maximum length of the fiber-matrix gap.…”

Different amount of raw Ketuki powder (average diameter: 60 -120 µm) was mixed with the thermoplastic polymers such as ethylene-1-octene copolymer (EOC) and isotactic polypropylene (iPP). The melt mixing was performed using an internal mixture and resulting composites were studied for the effect on morphology and mechanical behavior using electron microscopy, tensile testing and thermogravimetric analysis (TGA). The microscopic results showed that the polymer matrix is not compatible with filler resulting in worsening of mechanical properties especially in case of the iPP-based composites. For the EOC composites the rubbery nature of the matrix material remains still visible. The TGA analysis revealed slightly worsened thermal stability of composites, while tensile properties were found to be deteriorated as well.

“…Besides, there are loading configurations in which the stress-strain curve does not cover the linear elastic one [10,11]. Furthermore, the invention of new composites possessing high fracture resistance properties takes place in the last years [12][13][14]. Therefore, in all cases aforementioned, development of plastic deformations may begin before the onset of crack growth.…”

The present article is concerned with nonlinear fracture behavior of single cantilever beam made of unidirectional fiber-reinforced polymer composite. A theoretical study is performed assuming that the composite follows the stress-strain relation of an elastic-perfectly plastic material in both tension and compression. For this purpose, a model based on mechanics of materials is used. The fracture investigation is performed using path-independent J -integral where the contour of integration is chosen to coincide with the beam contour. Several closed-form analytical solutions that correspond to different ratios between crack length and beam length are obtained. It is shown that when the material nonlinearity is taken into account, an increase in J -integral value is observed. This finding is attributed to the increase in strain energy dissipation due to nonlinear deformation.Keywords Single cantilever beam · Mechanics of materials · Elastic-plastic fracture behavior · J -integral

“…Solid glass microspheres are special type of filler that induces improved process ability and service performance in injection-molded polypropylene-matrix composites. Higher thermal conductivity, dimensional stability and small and well-distributed internal stress are three qualities of the glass microsphere-filled PP composites [3,4].…”

In this study, the isotactic polypropylene, a semicrystalline polymer, was used as a matrix for composites containing 20% and 40% (by weight) of glass bead filler. Selected surface treatment was applied to obtain different adhesion between particles and polymer matrix. In addition to non-treated filler, filler treated with i) a release agent (labelled as NO adhesion) and ii) an adhesion promoter (labelled as GOOD adhesion) were incorporated into the matrix. The morphology, tensile mechanical and fracture behaviour (J-integral) were investigated. Morphology observation revealed a poor interfacial adhesion in the case of non-treated and "NO adhesion" samples represented with debonding of particles. In contrast, strong particle-matrix interactions were confirmed in "GOOD adhesion" samples. The presence of rigid filler particles increased the stiffness, while strain at break was decreased with the lowest value for the composites with strong interfacial adhesion. On the other hand, the higher rigidity and lower deformability decreased in fracture toughness.
