CA Composites offers two cryogenic prepreg variants — a Unidirectional (UD) and a Plain Weave — both built on the same toughened cryogenic epoxy resin system. Both grades deliver outstanding mechanical performance and exceptional resistance to extreme cold, qualified for continuous service down to −269 °C (liquid helium). They can be processed via autoclave, vacuum bag, or compression moulding, curing between 90–150 °C.
CAG6132U0-200
E-glass UD prepreg optimised for maximum axial stiffness and strength. Ideal where load is predominantly uniaxial — pressure vessels, structural tubes, and long-beam applications. Tensile strength up to 912 MPa.
CAG6133P1-200
E-glass 1×1 plain weave prepreg offering balanced biaxial properties and excellent drapeability. Well suited to complex geometries, tanks, and multi-axis loading. Flexural strength 478 MPa with easy lay-up.
