Abstract
Certain configurations of composite articles including a functional film layer are described. The functional film layer can be used to bond a skin layer to an underlying core layer to prevent delamination of the skin layer from the core layer. The core layer can be a cellulose based material or can be a non-cellulose based material. The composite articles can be used in vehicle load floors and vehicle headliners that can resist delamination over wider temperature ranges and/or more extreme environmental conditions than existing articles.
Claims21
A composite article comprising:
- a core layer;
- a first skin;
- and
- a first functional film disposed on a first surface of the core layer and between the core layer and the first skin, wherein the first functional film is effective to bond the first skin to the core layer after environmental cycling of the composite article over a temperature range of −40 degrees Celsius to +85 degrees Celsius without delamination of the first skin from the core layer.
