Multilayer thermoset polymer matrix and structures made therefrom

A composite thermoset polymer matrix structure comprising:

• a) a metal substrate;
• b) a first layer comprising a first thermoset polymer resin, said first layer being cured such that said first layer is substantially solid and is disposed around said metal substrate;
• and
• c) a second layer comprising a second thermoset polymer resin and a first additive agent heterogeneously disposed but substantially evenly mixed within said second thermoset polymer resin, said second layer being cured such that said second layer is substantially a solid and is homogeneously bonded to said first layer and disposed around said first layer.

A tubular structure, comprising:

• a) a first layer comprising a suspension of a first thermoset polymer resin and a first additive agent heterogeneously disposed but substantially evenly mixed within said first thermoset polymer resin, said first layer being cured such that said first layer is substantially a solid;
• and
• b) a second layer comprising a second thermoset polymer resin, said second layer being cured such that said second layer is substantially a solid and is homogeneously bonded to said first layer,
• wherein said first and second layers together define a freestanding tubular structure having an open lumen.

An adhesive sheet structure, comprising:

• a) a first layer comprising a suspension of a first thermoset polymer resin and a first additive agent heterogeneously disposed but substantially evenly mixed within said first thermoset polymer resin, said first layer being cured such that said first layer is substantially a solid;
• b) a second layer comprising a second thermoset polymer resin, said second layer being cured such that said second layer is substantially a solid and is homogeneously bonded to said first layer;
• and
• c) an adhesive layer disposed on one of said first and second layers.
