    Mike, how many layers of fiberglass cloth did you use?

    found epoxy to be the best when using with SMC

    also use rope to act as extra reinforcement makes repair rock solid

    this one was a bit messy but will never break

    it's works like steel reinforcement in concrete

    seen fiberglass still expand even after a heap of layers the rope stops any chance of expansion or flex

    THE FUNDAMENTALS OF FIBERGLASS

    A typical thermosetting epoxy resin has a tensile strength below 10,000 psi and is quite brittle. When such a resin is reinforced with glass fibers the resulting composite can have a tensile strength between 45,000-50,000 psi. It also becomes extremely resistant to impact damage. This high strength for the relatively low weight is the fundamental reason that fiberglass composites are popular. Another significant reason is their tailorability. Since the reinforcement can be added in any direction, layers can be built up which are perfectly oriented with the stress the part is to encounter. This saves additional weight by removing unnecessary material from areas with little stress. Other reasons for composite popularity are how easily these materials can be formed into complex shapes, that they have superior resistance to most environments and they can be used by most individuals without a major investment in equipment.

    Fiberglass is only one type of reinforcement. Other common types are carbon fiber and Kevlar® . These can be explained shortly in greater detail where their importance and variety can be covered adequately in the link below.

    Here is an EXCELLENT link over fiberglass
    It also touches upon Kevlar and Carbon Fiber.
