CRTM™ (continuous resin transfer molding) panels are high quality composite sandwich panels with tailored, multi-axial fiber reinforcements, high-fiber volume contents and very low void content. These custom-engineered products are available with a wide variety of core materials, including end-grain balsa, foam or engineered woods. Laminate skin face-sheets are also available with continuous fiberglass and/or carbon fiber reinforced polyester, vinyl ester and epoxy or custom resins.
CRTM panels are specifically designed for applications needing a high stiffness-to-weight ratio. 面板经过定制设计以满足客户需求，通过改变芯材厚度来影响刚度，改变芯材材料来影响重量，改变纤维来改变刚度重量比，改变树脂材料来影响强度。
While similar to pultrusion, the CRTM production method offers more consistent quality throughout the panel. This is possible because, unlike a pultrusion process where the resin is applied to the fiber before it enters the die, with CRTM the resin is injected directly into the die for better control of fiber alignment and resin kinetics. This process yields high performance, constant cross-section composite structures that offer superior quality and are more efficient than hand lay-up processes. And unlike typical wet bath pultrusion processes, Glasforms’ injection process effectively minimizes volatile organic compounds (V.O.C.) emissions.
