Processing instructions
Always wear protective gloves and eye protection for grinding or rework.
To avoid any new soiling the repair should be completed shortly after cleaning the damaged area.
Do not use any waxed mixing beakers for mixing the resin and hardener. Use non-paraffined paper cups, polyethylene-coated paper cups or polystyrol cups, that should also have a smooth wall and a level base, for the mixing vessel.
Always observe manufacturer's specifications regarding storage, mixing and processing.
Care must be taken to ensure that the container (resin, hardener) does not have the second component inadvertently added to it through putty or a mixed-up cap.
For small quantities of resin/hardener the hardener should be weighed first and then the resin added.
In the opposite instance, i.e. resin is added first, any excess addition of hardener may result in premature hardening of the mixture.
Resin / hardener mixtures have a limited processing time. It is therefore absolutely necessary to complete all preparations for gluing/laminating before starting to mix the resin/hardener.
The mixing ratio of resin/hardener is 100:18 parts by weight.
Adding additional hardener does not result in more rapid curing, but rather only poorer characteristics!
Mixtures of approx. 50 g should preferably be measured using a digital scale or letter balance. Measuring cups may also be used as an alternative.
Technical terms
ABS
Acrylonitrile-butadiene-styrene.
Mixed polymer is similar to PVC, thermo-stable and temperature-resistant up to 70 °C.
CRP
Carbon-fiber-reinforced plastic.
CFRP
Carbon reinforced plastic.
Delamination
Removal of fibrous material (fabric) from matrix material (resin).
FC
Fiber composite.
FRP
Fiber reinforced plastic.
GRP
Glass fiber reinforced plastic.
Hardener
Hardener (VE2896) is the second chemical components for triggering the cross-linking reaction of the prepolymers of thermoset plastics or elastomers (resin/hardener mixture).
Laminate
Material composed of several layers; here several layers of fiber fabric that are baked together by amatrix material, in this instance epoxy resin, to form a stable component.
Surface repair (Stage 1)
Repair in areas that do not exert any influence on the component rigidity and strength or on existing fastening points such as, e.g. hinges.
The damage is superficial only, e.g. scratches, notches, abrasion and it does not fully penetrate the component.
Tapered overlap, butt-joints
Butt joints are understood to refer to the beveled grinding of a component. Starting from an edge area the material erosion decreases continuously so that a slope is created.
The butt joint length l is taken from the butt joint ratio, which is generally 1:20. With a material thickness of 2 mm, the butt joint length is: l = 2 mm x 20 = 40 mm
Repair that penetrates the laminate (Stage 2 and 3)
Repair in permitted, specified areas that influences the strength and function of a component or the entire system (e.g. cab).
Damage that penetrates the laminate is, e.g. cracks, holes, fractures that fully penetrate the laminate.
Matrix material
Material that combines the fibers (e.g. epoxy resin and hardener).
Pot life
Time period in which a resin/hardener mixture becomes usable after all the components have been mixed together for an application.
The pot life may not be exceeded.
Actual magnitude of damage
The magnitude/expansion of the actual damage may be greater than the visible extent of the damage. Impact of collisions or strikes on the fiber composite components can lead to delaminations, which are invisible from the outside.
