Real Carbon Fiber Composite Plate 2×2 Twill 3M Adhesive Backing 35.4" x 19.7". Carbon Fiber Plate With Epoxy and 3M Adhesive Backing. Cross-plied layup will yield a panel with higher structural integrity, which many applications may require. Laminate stacking and ply orientation can be adjusted for specific applications; for example, if you require greater panel strength in a particular direction, you want to avoid increasing the weight with additional plies. The detailed lay-ups and fabric stack list can be requested for each of our panels. Please specify the panel model number when inquiring. Epoxy: All panels are made with a high-performance epoxy resin that offers excellent mechanical functions, clarity, and improved UV stability. An elevated post-cure temperature is applied to increase the mechanical strength of the panel, resulting in a higher Tg and enhancing the inter-laminar shear strength.
