Hybrid composites are made by incorporating two or more different types of fillers in a single matrix that is highly tailorable. Carbon fiber (CF) reinforced composites have been well developed for certain industries such as aerospace and sporting goods. However, the high cost of carbon fiber, as well as lack of cost effective processing technologies for mass production, prevents its penetration to many different markets. Wood fiber (WF), an environmentally sustainable bio‐fiber, has been used widely in making wood/plastic composites (WPCs) for building products and automotive applications, due to its low cost and lightweight. Nevertheless, WPCs have very limited structural applications where strong mechanical properties are required. Incorporating CF and WF into a polymer matrix to make hybrid composites through injection molding, would be a path to expanded applications for both. This paper investigated the injection molding of CF‐WF/polypropylene hybrid composites and their mechanical properties. The effects of fiber content and hybridization on the mechanical properties were studied. POLYM. COMPOS., 39:3329–3335, 2018. © 2017 Society of Plastics Engineers
