Processes

Matched Die Molding

Resin Transfer (RTM) - Option for closed molding. Two finished surfaces. RTM is cost effective over APM or hand lay-up when quantities are sufficient to justify tooling.

Bulk Molding Compound (BMC) - Compression Molding

Sheet Molding Compound (SMC) - Compression Molding

Reaction Injection Molding (RIM) - Injected into a closed mold at low pressure

Open Molding

Vacuum Infusion (VIP) - Open mold. One finished surface. Reinforcement laid up dry inside a mold that has been sprayed with gelcoat and a thin layer of chopped mat skin coat. It is then covered with a layer of peel-ply, atop of which is placed an airtight membrane that is sealed at the edges. A vacuum manifold is fitted along one edge of the mold and a resin supply manifold is fitted along the other edge. Less resin and more fiber reinforcement per unit of volume is achieved which leads to greater strength in relation to weight.

                               

Materials

Resin systems: Thermoset polyester resins, urethane resins, and vinyl ester resin systems.

Reinforcement materials:  The primary function of reinforcement material is used to enhance properties of the resins.  Many types of fibers can be used for composites, including but not limited to, carbon, several types of glass (E, C, S or R, S2 or A), Kevlar ®, and natural fibers.   These are available in mats and strands known as rovings or twisted into yarns.  The fibers may be stitched or woven into various 2-D or 3-D architectures. See examples of  RTM reinforcement.

Core Materials: Foam, balsa Wood and Honeycomb cores and many more.

Colors: In mold color.

With an engineered, oriented composite structure, a crack will not propagate in the same manner as metal; the fibers act as "crack arrestors" and the loads find alternate resolution paths through adjoining fibers.
