The Types segmentation distinguishes between thermoset and thermoplastic carbon‑fiber composites, each with distinct processing routes and performance profiles. Thermoset matrices—primarily epoxy‑based—dominate the market, contributing approximately 70 % of total spend, because of their superior fatigue resistance, proven aerospace heritage, and established certification pathways. Within thermosets, prepreg and resin transfer molding (RTM) are the principal sub‑types, with prepreg favored for high‑precision, low‑volume parts and RTM for larger, structurally critical components. Thermoplastic composites, accounting for the remaining 30 %, are gaining traction due to their recyclability, faster cycle times, and impact resistance; they are typically processed via autoclave‑free consolidation or injection molding. Sub‑types include polyetheretherketone (PEEK) and polyphenylene sulfide (PPS) systems, which are increasingly selected for engine‑bay and high‑temperature applications. This type‑based market taxonomy elucidates the material‑choice dynamics that shape investment, R&D focus, and ultimately the scale of the Carbon Fiber Composites in Aerospace market.
