Abstract
The rigid hollow protection casing (30) includes a first rigid layer (10) composed of a matrix of a first thermoplastic material (11) including in its interior at least one long-fibre fabric layer (12) selected from fibreglass, carbon fibre and/or aramid fibre and comprising between 45% and 65% of the total weight of the first layer (10); a second overlapping rigid layer (20) exterior to the first layer (10), the second layer (20) being entirely composed of a matrix thereof or of a second thermoplastic material (21), the second layer (20) comprising between 2% and 10% of the total weight of the casing (30).
Claims11
A rigid hollow protection casing comprising
- a first layer, which is rigid, composed of a matrix of a first thermoplastic material;
- and
- a second layer, which is rigid and composed of a matrix of a second thermoplastic material, is externally overlapped to the first layer;
- the matrix of first thermoplastic material comprises at least one layer of long-fibre fabrics embedded in its interior, long fibres are selected from fibreglass, carbon fibre and/or aramid fibre and comprise between 45% and 65% in total weight of the first layer;
- the second layer coats completely one exterior side of the first layer, comprises between 2% and 10% of the total weight of the casing and is entirely composed of the second thermoplastic material lacking long-fibre fabrics, providing a smooth finish to the casing, and
- the first thermoplastic plastic material has a lower melting point than the second thermoplastic plastic material and the first thermoplastic plastic material has intrusions penetrated within the second thermoplastic plastic material;
- or the second thermoplastic plastic material has a lower melting point than the first thermoplastic plastic material and the second thermoplastic plastic material has intrusions penetrated within the first thermoplastic plastic material;
- the first and second thermoplastic plastic materials being interwoven through the intrusions, thereby producing a monolithic and resistant assembly.
