laminatedplussic

Laminatedplussic is a term used to describe a laminated composite material that integrates silicon carbide (SiC)–containing interlayers or SiC-reinforced sheets within a multilayer laminate. The concept aims to combine the favorable properties of polymer or resin-based laminates with the high hardness, thermal stability, and electrical characteristics of SiC. The naming convention is not universally standardized and may vary between research groups.

Composition and variants: A typical laminatedplussic stack consists of alternating layers of a polymeric or resin matrix film (such as epoxy, polyimide, or polyester prepregs) and SiC-containing interlayers or ceramic sheets. Variants may use particulate-filled interlayers, continuous SiC foils, or SiC whisker-reinforced layers. The overall design targets a balance of stiffness, toughness, and thermal management.

Manufacturing: Production commonly involves laminate stacking followed by hot-pressing or autoclave curing, with vacuum bagging to remove air. Some approaches incorporate low-temperature lamination to limit interfacial diffusion; others use high-temperature sintering to densify ceramic layers. Interfacial bonding and residual stresses are important considerations.

Properties and applications: Laminatedplussic materials may exhibit enhanced in-plane thermal conductivity, high hardness, improved wear resistance, and tailored coefficient of thermal expansion. Potential applications include electronics cooling substrates, lightweight aerospace components, and protective panels where combined stiffness and thermal performance are valued. Real-world performance depends on interfacial adhesion and layer architecture.

Advantages and limitations: Advantages include tunable mechanical and thermal properties, corrosion resistance, and potential for damage tolerance through layer design. Limitations involve higher material and processing costs, potential brittleness of ceramic layers, moisture sensitivity at interfaces, and challenges in large-scale manufacturing.
