Abstract
This disclosure provides methods for the chemical modification of microbial derived triglyceride oils, use thereof in polyurethane chemistries, and incorporation thereof as a core material alone or as part of a wood core composite in the production of sporting goods equipment, including, for example, alpine skis, touring skis, cross country skis, approach skis, split boards, snowboards, and water skis.
Claims22
An elongate composite article comprising:
- a plurality of elongate polyurethane foam layers;
- a plurality of elongate wood layers, wherein each elongate polyurethane foam layer of the plurality of elongate polyurethane foam layers is laminated to one or more elongate wood layers of the plurality of elongate wood layers;
- an upper surface formed from both the plurality of elongate polyurethane foam layers and the plurality of elongate wood layers;
- and
- a lower surface formed from both the plurality of elongate polyurethane foam layers and the plurality of elongate wood layers, wherein the distance between the upper surface and the lower surface is less than 20 mm,
- wherein the article has a specific strength at yield of about 0.5 MPa/kg·m3 to about 2 MPa/kg·m3 as assessed by three-point bend flexural testing, wherein a load is applied downward to the upper surface of the article.
