In this paper, the authors perform several three-point bending tests on a typical stacking sequences used in composite structures. Inspection techniques involving a digital microscope are used to study the successive failures and the effect of the thickness ratio (l h−1) on nonlinear behaviour. It was found that successive failures depend on the stacking sequence where the orthogonal sequences have a significant effect on the delamination between the plies. To describe the nonlinear behaviour observed, Von-Karman’s large deflection theory and classical plate theory (CPT) are employed in the formulation of analytical modelling used in this work. The Riccati equation obtained leads to predict the experimental nonlinear curves with good accuracy. However, a slight dispersion between the experimental and analytical curves less than 11% was observed at large deflection.","PeriodicalId":20245,"journal":{"name":"Plastics, Rubber and Composites","volume":"45 1","pages":"145 - 153"},"PeriodicalIF":2.0,"publicationDate":"2021-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91202935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Afterward, a series of shape-memory films were obtained by UV (at around λ=365 nm) irradiation crosslinking. A sequence study and comparison on the properties changes caused by the effect of irradiation temperature was carried out and it turns out that the gel fraction, shape-memory properties and tensile properties of the PCL films, which were photo-crosslinked at 55°C, were significantly higher than that at 25°C. The effect of photoinitiator contents and irradiation time on gel fraction, shape memory properties and tensile properties was also studied.

The volume fraction and distribution arrangement of fiber reinforcement were designed to evaluate the effect of fiber arrangements on tensile properties of the printed composites. The experimental results proved that some outer and inner defects reduced the surface smoothness and tensile properties based on the analysis of macro and micro morphology. The fiber distributed evenly contributed to the dimensional precision and stability, as well as tensile properties. With the increasing fiber volume, the elastic modulus and ultimate tensile strength both approximately increased while the strain at break decreased.

The increase in the temperature, the pressure, the flow velocity and the percentage of fillers additives (ASP400) induce an augmentation in the diffusion coefficient and the amount of absorbed humidity. We can affirm that the flow velocity and the pressure have a higher impact on the diffusion parameters than the temperature.
