Abstract
A board includes fibers and thermoplastic resin and has a first surface and a second surface that is opposite from the first surface. The board includes a flat body member having edges, a bent portion, a hole, and a filling portion that is made of thermoplastic resin and in the hole. The bent portion extends from one of the edges of the flat body member and includes an edge of the board. The bent portion includes an angled portion that extends along the one of the edges of the flat body member and the bent portion extends from the angled portion at an inclination angle with respect to the flat body member such that the first surface of the angled portion is stretched. The hole is in the first surface of the angled portion.
Claims18
A board including fibers and thermoplastic resin and having a first surface and a second surface that is opposite from the first surface, the board comprising:
- a flat body member having edges;
- a bent portion that extends from one of the edges of the flat body member and includes an edge of the board, the bent portion including an angled portion that extends along the one of the edges of the flat body member, the bent portion extending from the angled portion at an inclination angle with respect to the flat body member such that the first surface of the angled portion is stretched;
- a hole that is in the first surface of the angled portion;
- and
- a filling portion that is made of thermoplastic resin and in the hole.
A method of producing a board, the method comprising:
- forming a preboard by heating and pressing a mat with a pressing die, the mat including fibers and thermoplastic resin;
- cutting the preboard to form a hole on a first surface of the preboard such that an opening of the hole is on the first surface;
- pressing the preboard having the hole at a temperature at which the thermoplastic resin is not molten to bend the preboard along the hole such that the first surface is stretched to enlarge the opening of the hole, and obtaining a board base member;
- and
- supplying the thermoplastic resin into the hole having an enlarged opening.
