Additive manufacturing of multilayered polymer composites: Durability assessment
Payami Golhin, Ali; Srivastava, Chaman; Tingstad, Jens Fossan; Sole, Aditya Suneel; Strandlie, Are; Grammatikos, Sotirios (Chapter, 2022)This study examines the impact of additive manufacturing (AM) settings on the durability of 3D-printed polymer composite objects in terms of object color appearance and corresponding mechanical properties when subjected ... -
A comparative study on the effect of hot/wet and hot/dry aging environments on the degradation of filament winded composites
Srivastava, Chaman; Strandlie, Are; Alcock, Benjamin; Grammatikos, Sotirios (Chapter, 2022)Predicting the long-term response of polymer composite materials is a continuous challenge to the composite industry. The service aging of structural composites has different effects on composites’ physicochemical behavior ... -
Comparison of the effect of thermal and hygrothermal sub-Tg aging on the durability and appearance of multilayered filament wound composite structure
Srivastava, Chaman; Alcock, Benjamin; Strandlie, Are; Grammatikos, Sotirios (Peer reviewed; Journal article, 2024)The study conducts an experimental investigation to compare the effect of accelerated aging on a glass fiber/vinylester matrix filament wound composite. Two static aging conditions, thermal and hygrothermal, were chosen. ... -
Effects of accelerated aging on the appearance and mechanical performance of materials jetting products
Payami Golhin, Ali; Srivastava, Chaman; Strandlie, Are; Sole, Aditya Suneel; Grammatikos, Sotirios (Peer reviewed; Journal article, 2023)As a result of the associated costs and environmental impacts, Material Jetting (MJT) plays a limited role in Additive Manufacturing (AM). Research on the durability and long-term performance of MJT objects by evaluating ... -
On the Response to Hygrothermal Ageing of Fully Recyclable Flax and Glass Fibre Reinforced Polymer Composites
Das, Subrata Chandra; Srivastava, Chaman; Goutianos, Stergios; La Rosa, Angela Daniela; Grammatikos, Sotirios (Peer reviewed; Journal article, 2023)The present work studies the response to hygrothermal ageing of natural fibre composites (NFCs) against synthetic fibre composites when using three different types of polymers as matrices. For ageing, coupons were fully ... -
Theoretical and Experimental Determination of Thermomechanical Properties of Epoxy-SiO2 Nanocomposites
Adnan, Mohammed Mostafa; Kroyan, Arpenik; Srivastava, Chaman; Grammatikos, Sotirios; Glaum, Julia; Ese, Marit-Helen Glomm; Schnell, Sondre Kvalvåg; Einarsrud, Mari-Ann (Peer reviewed; Journal article, 2023)Improvements in the thermomechanicalproperties of epoxy upon inclusion of well-dispersed SiO2nanoparticles have been demonstrated both experimentally and through molecular dynamics simulations.The SiO2was represented by ... -
Three-Dimensional Analysis of Porosity in As-Manufactured Glass Fiber/Vinyl Ester Filament Winded Composites Using X-Ray Micro-Computed Tomography
Srivastava, Chaman; Agostino, Pietro; Stamopoulos, Antonios G.; Alcock, Benjamin; Strandlie, Are; Grammatikos, Sotirios (Peer reviewed; Journal article, 2023)Filament winding is a technique to manufacture tubular composite structures and, therefore, is among the most appealing techniques for fabricating critical structures such as hollow tubes. Despite the recent advances, these ...
