“…At the lowest CF loading of 0.5 wt%, the large majority of the fibers are within the 100-400 lm range with a mean average of 217 lm. By increasing the CF loading to 2wt% the mean length shifts to lower values, which are consistent with the literature [7]. At this concentration the large majority of the fibers (65%) are now being below 200 lm in length and the mean average is 170 lm.…”

“…However, in the particular case of a brittle type of fibrous reinforcement such as glass and carbon fibers, the shear mechanical action of the melt‐compounding process often results in breakage of the fibers, which in turn also limits the micro‐mechanical reinforcing efficiency of the fibers . Numerous studies have reported the relationship between fiber length and mechanical performance of the micro‐composites . It is now well established that in order to effectively improve the strength and modulus of the matrix, the fiber length needs to be preserved as much as possible during the process .…”

In this work, micro‐composite materials were produced by incorporating 3‐mm long reclaimed short carbon fibers into bio‐based nylon 11 via melt compounding. A systematic fiber length distribution analysis was performed after the masterbatching, compounding and an injection moulding processes using optical microscopy images. It was found that the large majority of the fibers were within the 200–300 μm in length range after the injection moulding process. The mechanical (flexural and tensile), thermo‐mechanical, and creep properties of the injection moulded materials are reported. We found that an enhancement in flexural and Young's modulus of 25% and 14%, respectively, could be attained with 2 wt% carbon fiber loading whilst no significant drawback on the ductility and toughness of the matrix was observed. The creep resistance and recovery of the nylon 11, tested using dynamic mechanical thermal analysis at room temperature and 65°C, was significantly improved by up to 30% and 14%, respectively, after loading with carbon fiber. This work provides an insight into the property improvement of the bio‐based polymer nylon 11 using a small amount of a reclaimed engineered material. POLYM.

“…8a, we use polypropylene (E PP = 1.665 GPa, ν PP = 0.36, see [47] and [48]) in the matrix and E-glass (E E = 73 GPa, ν E = 0.18, see [49]) in the fibers and vary the number of voxels to get an impression on the convergence rate of the relative error for increasing resolution. To obtain the geometries at the required resolution we use a voxel-representation of the fiber-reinforced plastic (FRP) with 4096 3 voxels and downsample according to Section 3.3.3.…”

“…On the other hand, addition of short fibers usually reduces the toughness in ductile matrix composites ( 1 1 -13). There are only a few studies on the effect of fiber content on the fracture toughness of short glass fiber reinforced rubber toughened polymer blends (14)(15)(16)(17)(18).…”

The effect of fiber content on the fracture toughness of short glass fiber reinforced and rubber toughened nylon-6 has been investigated using the essential work of fracture (EWF) analysis under both quasi-static and impact rates of loading. Under quasi-static loading rate, matrix plastic deformation played a major role. Addition of 10 wt% of short glass fibers into a rubber toughened nylon-6 matrix improved the fracture toughness substantially. This is due to the synergistic effect that comes from matrix yielding and fiber related energy absorption such as fiber debonding, fiber pull-out and fiber fracture. With further increasing the glass fiber content, up to 20 and 30 wtYo, even though plastic deformation could still take place on the fracture surfaces, the depth of the fracture process zones was much smaller when compared with the system with 10 wt?h of glass fibers. The reduction in fracture process zone caused the reduction in fracture toughness. Under impact loading rate, the unreinforced blend still fractured in a ductile manner with gross yielding in the inner fracture process zone and the outer plastic zone. The unreinforced blend therefore possessed higher fracture toughness. For the fiber reinforced blends, the matrix fractured in brittle manner and so fracture toughness of the reinforced blends decreased dramatically. The impact fracture toughness increased slightly after incorporation of a higher weight percentage of glass fibers.Rg. 1 7. Impactfracture surface of a 1 OGF SENB specimen. means that the glass fibers played an important role in the fracture energy absorption mechanisms under impact loading when the matrices behaved in a brittle manner.
