Abstract: Abstract In this paper, the effects of particle reinforcement on the tensile, compression and flexural properties, as well as the influence of cross head speed on the quasi-static punch shear properties of glass/epoxy composites are investigated. Laminated composites, which are manufactured by hand lay-up method consist of six layers of stitched glass fibers. As the particle reinforcement materials, pinecone and acorn powders with 1, 2, 3, 4 and 5 wt% ratios are used for the manufacturing of composites. The quasi-static punch shear behaviour of composites is elucidated at a room temperature through the force – deformation curves and the energy graphs at different test speeds (i.e., 1, 10 and 20 mm min −1 ). According to the experimental findings of quasi-static punch shear tests, it is concluded that the maximum contact force of each composite increases along with the punch shear test speed. Compressive strength of the acorn reinforced specimens shows their highest compressive value at the particle amount of 5 wt%, while pinecone-reinforced composites exhibit their highest compressive strength at the particle ratio of 2 wt%.
TL;DR: In this article, the effects of reinforcing polylactid (PLA) and poly(3-hydroxybutyrate-co-3hydroxyvalerate) (PHBV) biopolymers on the mechanical performance were studied.
TL;DR: In this article, the potential of grain by-product such as barley husk, coconut shell as reinforcements for thermoplastic as an alternative or together with wood fibres was investigated, where the particle morphology and particle size was investigated by scanning electron microscopy.
TL;DR: In this paper, the effect of fiber type and loading rate on composite mechanical properties was investigated and the results showed that the use of fiber in both virgin and recycled high-density polyethylene (VHDPE and RHDPE) composites had comparable mechanical properties with those of wood composites.
TL;DR: In this article, a composite damage model, namely MAT 162, which has been incorporated into LS-DYNA 970, was used to identify compression-shear and tension shear dominated modes of damage.
TL;DR: In this article, a technique was developed to improve the strength of unidirectional composites by enhancing the matrix properties through nanoparticles infusion, which showed a substantial improvement in elastic modulus of the modified epoxy.
