These are the figures for a Cure at 130 °C for 60 minutes on the press with 3 b ar pressure
Properties Test method Measure unit Typical values
Flexural strength EN2562 Mpa 850
Flexural modulus EN2562 Gpa 59
Tensile strength ISO 527 Mpa 650
Tensile modulus ISO 527 Gpa 59
Short Beam Shear EN2563 Mpa 65
TG (DSC) 20°C/min °C 140
That is from the manufacturers data.
However the data is only useful and valid if you use the same conditions and cure cycle - and there in is the problem with technical data for pre-pregs and to a lesser extent composites in general. This is why often manufacturers of the resins and fabrics only have available fibre specification and data for the resin. The professional designers will usually be doing the complex maths and CAD necessary to get the necessary figures for thier applications.
To answer the original question, can it be used for structural purposes - in many cases yes. Depends what you are making. When you compare it to the top level pre-pregs used in say Formula 1, parts made will be thicker and heavier with the varipreg. Obviously certain applications will need the extreme properties only the best pre-pregs can provide.
