Abstract
A composite material shell having a base plate made of thermoplastic resin and reinforcing fibers and multiple decorative pieces. Each of the multiple decorative pieces is made of a composite material containing thermoplastic resin and reinforcing fibers. An area of each of the multiple decorative pieces is smaller than an area of the base plate, wherein the multiple decorative pieces are non-directionally arranged, are overlapped, and are welded on the base plate whereby the composite material shell provides unique reflection and depth variations of visual effect.
Claims8
A composite material shell comprising:
- a base plate made of thermoplastic resin and reinforcing fibers;
- and multiple decorative pieces, wherein each of the decorative pieces is made of a composite material containing thermoplastic resin and parallel reinforcing fibers, an area of each one of the multiple decorative pieces being smaller than an area of the base plate, wherein the multiple decorative pieces are non-directionally arranged such that the reinforcing fibers of each decorative piece extend in a non-parallel alignment with the reinforcing fibers of the other decorative pieces, wherein the multiple decorative pieces are overlapped and are welded on the base plate;
- wherein the composite material shell is in a configuration capable of enclosing at least a portion of an electronic device.
A manufacturing method for a composite material shell comprising:
- a base plate preparation step:
- laminating prepreg sheets made of thermoplastic resin and reinforcing fibers to form a base plate;
- a decorative pieces manufacturing step:
- preparing multiple decorative pieces made of thermoplastic resin and reinforcing fibers, wherein each decorative piece comprises parallel reinforcing fibers, an area of each one of the multiple decorative pieces being smaller than an area of the base plate;
- a decorative pieces paving step:
- paving the multiple decorative pieces on the base plate, the multiple decorative pieces being overlapped, wherein the multiple decorative pieces are non-directionally arranged such that the reinforcing fibers of each decorative piece extend in a non-parallel alignment with the reinforcing fibers of the other decorative pieces;
- and a hot compression step:
- heating the base plate and the multiple decorative pieces and compressing the base plate and the multiple decorative pieces thereafter such that the multiple decorative pieces are welded on the base plate and the resulting composite material shell is in a configuration capable of enclosing at least a portion of an electronic device.
