...Anni Cao; Christer W. Elverum Purpose Fibre-reinforced polymers offer enhanced in-plane mechanical properties in material extrusion (MEX) additive manufacturing, expanding its applicability. However, fibres have minimal impact on the mechanical properties in the build direction, limiting...

...Bo Chen; Peizhi Yu; Yi Su; Caiwang Tan; Xiaoguo Song; Yunxia Chen Purpose Laser metal deposition is an ideal method to fabricate functionally graded materials (FGMs) whose properties vary with the dimensions, and the transition layer would highly influence the mechanical properties. However...

... to be removed by heat treatment. This paper aims to remove those microvoids in as-built AlSi10Mg alloys by hot forging and enhance their mechanical properties. Design/methodology/approach AlSi10Mg samples were built using prealloyed powder with a set of optimized LPBF parameters, viz. 350 W of laser power...

...Jibing Chen; Shisen Huang; Nan Chen; Chengze Yu; Shanji Yu; Bowen Liu; Maohui Hu; Ruidi Li Purpose This paper aims to identify the optimal forming angle for the selective laser melting (SLM) process and evaluate the mechanical properties of the SLM-formed GH3536 alloy in the aero-engine field...

... First, the morphology, processibility, thermal and mechanical properties of PA12 regenerated powder, consisting of 50 wt% new and 50 wt% recycled powder, as well as corresponding printed specimens, were evaluated to characterize the effects of previous SLS processing. Second, flame-retardant PA12...

...Wei Chen; Qiuju Zhang; Ye Yuan; Xiaoyan Chen; Qinghao He Purpose Continuous fiber reinforced thermoplastic composites (CFRTPCs) with great mechanical properties and green recyclability have been widely used in aerospace, transportation, sports and leisure products, etc. However, the conventional...

... more, thereby leading to an increase in width and a decrease in the layer height of the weld bead. The mechanical properties and wear resistance significantly increased owing to reinforcement. Comparatively, samples with large WC particles showed inferior tensile properties owing to their higher...

.... The hollow design in HTPMS can enhance the mechanical properties and energy absorption of the cellular structure. Finite element analysis also demonstrates that the hollow design can reduce stress concentration, which improved the compressive curves from a severely fluctuating state to a relatively flat...

... failure analysis including the micro imaging and morphology have been performed. The underlying mechanism is that the axial tensile strength of the OF and the interfacial adhesion between PLA and OF compete to enhance the mechanical properties of the composite. Findings It is found that 10%–20...

...Kaiyang Zhu; Zichen Deng; Shi Dai; Yajun Yu Purpose This study aims to focus on the effect of interlayer bonding and thermal decomposition on the mechanical properties of fused filament fabrication-printed polylactic acid specimens at high extrusion temperatures. Design/methodology/approach...

...Mingkang Zhang; Yongqiang Yang; Meizhen Xu; Jie Chen; Di Wang Purpose The purpose of this study is focused on the mechanical properties of multi-materials porous structures manufactured by selective laser melting (SLM). Design/methodology/approach The Diamond structure was designed...
