Break resistant composite stringer system

A sports board comprising:

• a. a sports board front end, and a sports board rear end;
• b. a break resistant composite stringer system including:
• i. an elongated stringer body having a stringer top surface, a stringer bottom surface, a stringer left surface and a stringer right surface, and;
• ii. an upper fibrous channel formed as an upper U channel, wherein the upper U channel is fibrous and includes an upper U channel right flange and an upper U channel left flange, wherein the upper U channel right flange is vertically oriented and wherein the upper U channel left flange is vertically oriented, wherein an inside surface of the upper U channel is bonded to the stringer right surface, the stringer top surface, and the stringer left surface;
• and
• iii. a lower fibrous channel formed as a lower U channel, wherein the lower U channel is fibrous and includes a lower U channel right flange and a lower U channel left flange, wherein the lower U channel right flange is vertically oriented and wherein the lower U channel left flange is vertically oriented, wherein an inside surface of the lower U channel is bonded to the stringer right surface, the stringer bottom surface, and the stringer left surface;
• c. a foam core, wherein the foam core covers the break resistant composite stringer system;
• and
• d. a foam skin, wherein the foam skin covers the foam core, wherein the upper fibrous channel and the lower fibrous channel both have a web thickness in the range of 0.5 mm to 5 mm, a flange thickness in the range of 0.5 mm to 6 mm, a web width in the range of 5 mm to 30 mm and a flange height in the range of 3 mm to 30 mm, wherein the upper fibrous channel and the lower fibrous channel are made in multiple layers including an upper channel layer and a lower channel layer.
