Abstract There is a global acceleration in the employment of inorganic fiber-reinforced wood– plastic composites in various fields. The durability of composites is challenged by hot and humid environments, where their service life is greatly shortened compared to that in normal environments. Therefore, it is rare to adding basalt fibers (BF) for wood plastic composites, to extend the actual applications; how to better improve the service life is important issue. So, the physical, mechanical, and thermal properties of composites are deeply investigated for durability. In this study, BF, which is a relatively stable fiber, is selected as the research object. The results indicate that the physical, mechanical, and thermal properties of composites improved by BF. The mechanical properties of composites are optimal when the content of BF reached 10%. Water resistance of the impregnated composites improves more than that of non-impregnated composites. The physical and mechanical properties of composites were observed by scanning electron microcopy. Good interfacial adhesion limits the mobility of polymer chains lead to good performance. Additionally, the thermal properties are enhanced owing to the addition of BF, especially the low linear coefficient of thermal expansion and the high thermal decomposition temperature. BF has a positive effect in reinforced composites. Keywords Inorganic fiber · Composites · Expansion coefficient · Interfacial adhesion · Decomposition temperature

Introduction As one of the new composite materials developed in the twenty-first century, wood–plastic composites (WPCs) have an important role in different fields, owing to their good mechanical and thermal properties [1–3]. The amount of WPCs sold has risen up to one million tons, achieving a growth rate of 13% each year [4]. WPCs combine fiber and plastic at different ratios, thus reducing pure wood fiber with plastic [5, 6]. The advantages of plastic present in the wood–plastic composites expand the application of WPCs, which is already widely developed [7–9]. WPCs suffer from sunlight and hygrothermal damage from the environment extensively [10]. The long-term corrosion and aging damage of the properties of WPCs should be reduced in order to improve the physical [11], mechanical [12], and thermal properties [13] of these types of materials, which will improve not only the material quality but also its service life [14, 15]. Many domestic and foreign experts and scholars have conducted extensive res
