Wood waste is commonly treated as waste, and there is a problem for its disposal. Currently, fibers are used to produce paper, building material, and bioplastics, although wood-plastic composite materials have previously been developed, there are no reports of one with a polycaprolactone matrix. During this research, polycaprolactone-poplar wood composite materials were developed that were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, biodegradation, water uptake test, three-point bending mechanical properties, and temperature sweeping. Scanning electron microscopy images showed composite materials in a uniform matrix, spectroscopy showed the interaction of the carbonyl group of polycaprolactone and the stretch bond O-C-O with the OH groups of wood. Composite materials are resistant to hydrolytic degradation even under the effects of UV rays. According to the results, an appropriate material was obtained for product design, so a design proposal for it was eventually generated.
