For the sustainable boat production, a new composite material consisting of
PLA and wood was introduced in the study. Wood, yellow pine from the forests of the
Mediterranean region of Turkey, was in two form in the study: (1) 8% in weight in the
composite and (2) solid wood. From the both kind of the material, specimens were produced by additive manufacturing technique in two (parallel and cross) printing directions and after that, the specimens were subjected to accelerated aging processes representing long-term effects of marine environmental agents such as humidity, salt and
temperature in four conditions namely: (1) without, (2) one-week, (3) two weeks and (4)
four weeks aging. Tensile and compressive testing were performed for all the samples
and the results were given comparatively. A scanning electron microscope (SEM) analysis and thermal analysis were also performed to appreciate the bonding performance of
the materials and the environmental effects on the composite. According to the results,
newly introduced PLA/wood composite material was found usable for the interior design
elements whose the complex form and the limited exposure to the marine environment.
