“…The layers, shifting along the radial direction, disturb their own reinforcing strands mainly in this direction and in the section transverse to it. Taking into account the strongly negative effect of even slight deviations of the fibres reinforcing the laminate from the loading axis, 36,42 the load capacity of the laminate section drops very significantly in such a case. Similar behaviour of fibrous reinforcing structures was confirmed in literature.…”

“…Glass fibre preform deformation caused by stitching was studied in literature. 35,36 The phenomenology of the course of the stitched laminate failure was analysed in literature. 37 The study includes the manufacturing process of laminate panels by means of the RTM method on the basis of three types of preforms: plain woven fabric (classic), stitched plain woven fabric and 3D woven fabric.…”

The aim of the work is an assessment of the effect of the deformation (curvature) of reinforcing fibre preform caused by insertion into a mould on the laminate properties. The basis for the assessment is a comparison with an analogous laminate without deformation, i.e., made in a flat mould. The work includes the production of laminate panels by way of resin transfer moulding, on the basis of three types of preforms: plain woven fabric (classic), stitched plain woven fabric and three-dimensional woven fabric, as well as an evaluation of their mechanical properties in static bending tests (in the radial direction of the curved panels) and tensile tests (in the axial direction of the curved panels). The state of the laminate reinforcement structure was assessed by the means of computer tomography. The strength of the curved laminates, both in the radial and in the axial directions, is lower than in case of the equivalent flat laminates. The strength decrease proceeds together with the deformation degree. The stitched and three-dimensional laminates are much less prone to strength loss resulting from deformation than the classic laminate; they also exhibit lesser strength drops in the direction transverse to the stitch lines or the interweave strands than in the parallel direction. The curved classic laminate shows the biggest deviations of the fibre strands from rectilinearity as well as local structure anomalies, in comparison to the two other laminate types. In the curved three-dimensional laminate, the fibre strands are much more uniformly oriented than in the other two.

In this paper, the production of aggregate from car windshield cullet and the use of this aggregate, in various compositions with fine quartz sand, as the reinforcing phase of the epoxy matrix polymer concrete were used and the obtained samples were tested. The bending and compressive strength, Charpy’s impact resistance tests were performed on the obtained composites. The porosity, water absorption, and density were also determined. The tests performed have shown that the application of car windshield cullet in polymer concrete, seems to be a good way to recycle this waste. The highest compressive strength, equal to 101 MPa, was obtained by composites containing 20 vol% of milled glass. It is nearly 7 times higher than the value of traditional concrete tested simultaneously, which has about 15 MPa. The highest flexural strength was noted for the composite containing 35 vol% of the glass. Polymer concrete samples did not show high impact resistance, which was in the range of 5.85 - 10.13 kJ/m2 . However, it increases with increasing glass content and the highest value was obtained for the composite containing 50% of the glass volume. Among the polymer concrete samples, the best properties were obtained for the mixture of 35% sand, 35% ground glass and 30% epoxy resin. Open porosity of traditional concrete is 15.9%, and for polymer concrete it was lower than 0.38%. The large difference in open porosity and water absorption for traditional concrete and polymer concrete, allow us to conclude that the latter will have higher frost resistance. The test results clearly show the significantly better mechanical properties of polymer concrete than of traditional concrete.

“…20,21 The piercing size could influence the interlayer shear properties of preform including the number of filament in the stitched yarn and initial stitched yarn tension during stitching process. 22,23 The shear properties of the 3D angle interlock preform were studied by using the picture frame. Sun et al explained that the preform architecture, preform areal density and fiber linear density were critical parameters for enhancing the shear properties of the 3D preforms.…”

The in-plane shear properties of nanostitched three-dimensional (3D) carbon/epoxy composites were investigated. Adding the stitching fiber or multiwalled carbon nanotubes or nanostitched fiber into carbon fabric preform slightly improved the shear strength and modulus of stitched and stitched nanocomposites. The in-plane shear fracture of the base and nanostructures was extensive delamination and tensile fiber failures in the sheared region. But, the stitched and stitched nanocomposites had angular deformation of the stitching yarns in the fiber scissoring areas, shear hackles in the matrix and successive fiber breakages in the interlayers. Probably, this mechanism prohibited extensive interlayer opening in the nanostitched composites. The results exhibited that introducing the stitching fiber (1.44%) and multiwalled carbon nanotubes (0.03125%) in the base structure enhanced its transverse fracture properties as a form of confined delamination area. Therefore, the damaged tolerance properties of the stitched nanocomposites were enhanced.
