Product Details

Description

USA: width 19.69", weight 2.9 oz/yd²

UNIPREG® is a unidirectional epoxy carbon fibre prepreg that can be used wherever excellent mechanical and physical properties are required.

Pre-impregnated semi-finished products, so-called prepregs, offer maximum performance and a very wide range of applications, especially for complex components. Compared to other manufacturing processes, they anticipate a decisive step in the production of composite materials: the uniform impregnation of the fibre by the matrix. This achieves maximum mechanical performance on the one hand, and very efficient component production on the other. In addition, the user is spared the time-consuming impregnation process with resins.

The epoxy resin provides the best possible adhesion between the fibre and the matrix in the composite.

  • All filaments lie absolutely parallel (no thread grid) and are therefore optimally aligned
  • The thickness of the prepreg is constant across the width
  • All physical parameters have a very strict tolerance

Application: Excellent suitability for structural components.

Processing:
The prepreg is slightly sticky when uncured. It is therefore provided with protective covers on both sides to prevent the layers from sticking together unintentionally. The prepreg consists of silicone paper (white in the picture) and an embossed polyester film (blue in the picture).
Cut the prepreg to size for processing. Only then peel off the white silicone paper and place the prepreg into the mould with the sticky side down. As soon as it lies correctly, the embossed blue foil is peeled off the backside. In this way, several prepreg layers can be glued together as a "stack".
Curing then takes place under pressure (vacuum presses with foils) and heat (see below, "UNIPREG Technical Data Sheet").
