Abstract
An uncured fiber reinforced assembly that includes a reinforcement layer containing a fibrous material and at least one highly reactive curing agent. A matrix film layer is applied to the reinforcement layer so that it does not substantially impregnate the reinforcement layer. The matrix film layer includes at least one uncured epoxy resin and at least one latent epoxy curing agent. The assembly is designed for use in making snowboards and skis.
Claims8
A method for making an uncured composite structure comprising the steps of:
- A) providing a reinforcement layer having a first surface and a second surface that define the thickness of said reinforcement layer, said reinforcement layer consisting of a fibrous material and at least one highly reactive curing agent;
- and
- B) applying a matrix film layer to at least part of said first or second reinforcement layer surfaces wherein said matrix film layer consists essentially of at least one uncured epoxy resin and at least one latent epoxy curing agent wherein said matrix film layer does not substantially impregnate said reinforcement layer.
