    Hand Lay-Up The hand lay-up process involves manually placing layers of reinforcing fibers onto a mold and saturating them with resin. It is a popular method for producing simple composite parts with low tooling costs. Simple and cost-effective, ideal for small-scale production, allows for easy customization of parts.
    Resin Transfer Molding (RTM) RTM is a closed-mold process where dry fibers are placed into a closed mold, and a liquid resin is injected under pressure. This method ensures consistent fiber distribution and produces high-quality, void-free composite parts. Excellent control over fiber orientation, high strength-to-weight ratio, ideal for complex shapes and large-scale production.
    Autoclave The autoclave process involves placing pre-impregnated composite materials into a vacuum-sealed bag and subjecting them to high temperature and pressure in an autoclave. This method ensures proper consolidation and curing of the composite, resulting in superior mechanical properties. Exceptional strength and stiffness, excellent surface finish, suitable for aerospace applications, precise control over part dimensions.
    Pultrusion Pultrusion is a continuous process where reinforcing fibers are pulled through a resin bath, then into a heated die to cure the composite. This method allows for the production of long, constant cross-section profiles with high fiber volume fractions. Highly efficient process, excellent strength and stiffness, low material waste, ideal for producing rods, tubes, and structural shapes.
