Abstract
The present invention is a contoured press molded article comprising: a soy-based resin and a plant-based sheet, wherein the article is manufactured from the process comprising the steps of: impregnating the sheet with soy-based resin; precuring the sheet to remove water to form a premolded article wherein at least one region of a premolded article is reinforced with at least one additional layer of impregnated soy-based resin; pressing the premolded article into a contoured molded article, wherein the contoured molded article has a flexural strength that is greater than 20 MPas.

A contoured press molded article comprising:
- a soy-based resin and a plant-based sheet, wherein the article is manufactured from the process comprising the steps of:
- impregnating the sheet with soy-based resin;
- precuring the sheet to remove water to form a premolded article, wherein at least one region of the premolded article is reinforced with at least one additional layer of impregnated soy-based resin to provide said region with properties of greater strength or stiffness;
- pressing the contoured premolded article into a contoured molded article, wherein the contoured molded article has a flexural strength that is greater than 20 MPas.
A method of making a contoured press molded article comprising:
- impregnating a plant-based sheet with a soy-based resin;
- precuring the sheet to remove water and form a premolded article, wherein a region of the premolded article is reinforced with at least one sheet to impart greater strength or stiffness to the region.
- pressing the premolded article into a contoured molded article that has three-dimensional contours, wherein the precured article has a flexural strength that is greater than 20 MPas.
